What biodiverse geographic area is considered the birthplace of agriculture



What is Agri-agricultural biodiversity?

Agricultural biodiversity is a broad term that includes all components of biological diversity of relevance to food and agriculture, and all components of biological diversity that constitute the agricultural ecosystems, also named agro-ecosystems: the variety and variability of animals, plants and micro-organisms,…

Which region has the highest biodiversity?

Generally, the closer a region is to the Equator, the greater the biodiversity. At least 40,000 different plant species live in the Amazon rain forest of South America, one of the most biologically diverse regions on the planet. Only about 2,800 live in Canada’s Quebec province .

What is the definition of biodiversity in geography?

Biodiversity can also refer to the variety of ecosystems—communities of living things and their environments. Ecosystems include deserts, grasslands, and rain forests. The continent of Africa is home to tropical rain forests, alpine mountains, and dry deserts. It enjoys a high level of biodiversity.

How do you measure biodiversity in geography?

A common way to measure biodiversity is to count the total number of species living within a particular area. Tropical regions, areas that are warm year-round, have the most biodiversity. Temperate regions, which have warm summers and cold winters, have less biodiversity.


What geographic area is considered the birthplace of agriculture?

Fed by the waterways of the Euphrates, Tigris, and Nile rivers, the Fertile Crescent has been home to a variety of cultures, rich agriculture, and trade over thousands of years. Named for its rich soils, the Fertile Crescent, often called the “cradle of civilization,” is found in the Middle East.

What is an example of a factor that the genuine progress indicator takes into account that GDP per capita does not?

What is an example of a factor that the Genuine Progress Indicator (GPI) takes into account that GDP per capita does not? Income inequality, costs of environmental degradation, and increased social factors. What are the 5 stages of the demographic transition?

What is an example of population growth?

The early pattern of accelerating population size is called exponential growth. The best example of exponential growth in organisms is seen in bacteria. Bacteria are prokaryotes that reproduce largely by binary fission. This division takes about an hour for many bacterial species.

What is population growth in biology?

When scientists are studying a population that is a group of individuals of a particular species that are in a specific area, one of the things that they are interested in looking at is the population growth. Population growth is the change in the amount of individuals of that species over time.

How do the Genuine Progress Indicator and the Human Development Index differ from GDP as measures of development?

How do the Genuine Progress Indicator (GPI) and the Human Development Index (HDI) differ from GDP as measures of development? The GPI is an alternative to measuring development beyond just the economic focus of GDP. The GPI considers social and sustainability factors along with GDP data.

Why do some people believe that the genuine progress indicator is a better assessment of economic health?

GPI is an alternative metric to GDP but which accounts for externalities such as pollution. As such, GPI is considered to be a better measure of growth from the perspective of green or social economics. Proponents suggest that GPI is a better metric as it provides a full view of the health of a nation.

How are exponential and logistic growth models similar and different?

Exponential growth is a growth in population wherein the number of individuals increases. This happens even when the rate of growth does not change. As a result, it creates an explosion of the population. Logistic growth entails exponential growth in population along with a growth rate which is in a constant state.

What is logistic population growth?

In logistic growth, a population’s per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity ( K).

What is the birthrate in a human population?

Birth rate is the number of individuals born in a population in a given amount of time. Human birth rate is stated as the number of individuals born per year per 1000 in the population. For example, if 35 births occur per year per 1000 individuals, the birth rate is 35.

What is population growth in geography?

Definition: The annual average rate of change of population size, for a given country, territory, or geographic area, during a specified period. It expresses the ratio between the annual increase in the population size and the total population for that year, usually multiplied by 100.

What will happen to the population when the birth rate is larger than the death rate?

Natural increase in a population occurs where Birth rate is greater than death rate. That is, that there are more births than deaths in that population ion a year. Natural decrease occurs when death rate is greater than birth rate.

What is exponential growth Class 12?

(a)Exponential growth occurs normally when resources, i.e. food and space are unlimited. r is an important parameter assessing impacts of any biotic or abiotic factor on population growth. In exponential growth, when N in relation to time (t) is plotted on graph, the curve becomes J-shaped as show in graph.

What is agricultural biodiversity?

Agricultural biodiversity is the outcome of the interactions among genetic resources, the environment and the management systems and practices used by farmers. This is the result of both natural selection and human inventive developed over millennia. The following dimensions of agricultural biodiversity can be identified: 1) Genetic resources …

How is agricultural biodiversity maintained?

Agricultural biodiversity is largely shaped and maintained by human activities and management practices , and a large number of people depend on agricultural biodiversity for sustainable livelihoods.

What are the main units of production in agriculture?

Microbial and fungal genetic resources. These constitute the main units of production in agriculture, and include cultivated and domesticated species, managed wild plants and animals, as well as wild relatives of cultivated and domesticated species. 2) Components of biodiversity that support ecosystem services upon which agriculture is based.

What are the factors that affect agricultural biodiversity?

3) Abiotic factors, such as local climatic and chemical factors and the physical structure and functioning of ecosystems, which have a determining effect on agricultural biodiversity.

What are the genetic resources of plants?

Plant genetic resources, including crops, wild plants harvested and managed for food, trees on farms, pasture and rangeland species, Animal genetic resources , including domesticated animals, wild animals hunted for food, wild and farmed fish and other aquatic organisms, Microbial and fungal genetic resources.

What is biodiversity in biology?

Biodiversity refers to all the different kinds of living organisms within a given area. Biodiversity includes plants, animals, fungi, and other living things. Biodiversity can include everything from towering redwood trees to tiny, single-cell algae that are impossible to see without a microscope. Kinds of Biodiversity.

Which continent has the highest biodiversity?

Ecosystems include deserts, grasslands, and rain forests. The continent of Africa is home to tropical rain forests, alpine mountains, and dry deserts. It enjoys a high level of biodiversity. Antarctica, covered almost entirely by an ice sheet, has low biodiversity.

Why is biodiversity important?

Biodiversity is important to people in many ways. Plants , for instance, help humans by giving off oxygen. They also provide food, shade, construction material, medicines, and fiber for clothing and paper. The root system of plants helps prevent flooding.

What are the protected areas in Montana?

Many national parks, such as Glacier National Park in the U.S. state of Montana, protect biodiversity within the park by restricting extractive activities, such as mining and drilling. Marine protected areas (MPAs) have been established to preserve sea life.

What are the main functions of plants and animals?

Plants, fungi, and animals such as worms keep soil fertile and water clean. As biodiversity decreases, these systems break down. Hundreds of industries rely on plant biodiversity. Agriculture, construction, medical and pharmaceutical, fashion, tourism, and hospitality all depend on plants for their success.

Why are there wilderness areas?

Around the globe, thousands of wilderness areas have been set up to conserve plants, animals, and ecosystems. Local, national, and international organizations are cooperating to preserve the biodiversity of regions threatened by development or natural disasters.

Why is the genetic diversity of animals declining?

The creatures that survive have fewer breeding partners, so genetic diversity declines. Pollution , overfishing, and overhunting have also caused a drop in biodiversity. Global climate change —the latest rise in the average temperature around the globe, linked to human activity—is also a factor.

Which countries have the most biodiversity?

Some areas in the world, such as areas of Mexico, South Africa, Brazil, the southwestern United States, and Madagascar, have more biodiversity than others. Areas with extremely high levels of biodiversity are called hotspots.

What is the definition of biodiversity?

Biodiversity. Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.

Why is manure important to the Earth?

This manure can also be used to fertilize cropland. Many species provide important benefits to humans, including food, clothing, and medicine. Much of the Earth’s biodiversity, however, is in jeopardy due to human consumption and other activities that disturb and even destroy ecosystems.

What is genetic diversity?

genetic diversity. Noun. difference or variety of units of inheritance (genes) in a species. hotspot. Noun. area that contains a significant level of biodiversity and is threatened with destruction. naturalist. Noun. person who studies the natural history or natural development of organisms and the environment.

What are the species that live in grassland?

A single grassland can contain a wide range of species, from beetles to snakes to antelopes. Ecosystems that host the most biodiversity tend to have ideal environmental conditions for plant growth, like the warm and wet climate of tropical regions. Ecosystems can also contain species too small to see with the naked eye.
