What is the science of agriculture?
Agriculture is the art and science of cultivating the soil, growing crops and raising livestock. It includes the preparation of plant and animal products for people to use and their distribution to markets. Agriculture provides most of the world’s food and fabrics. Cotton, wool, and leather are all agricultural products.
How did agriculture help people?
Agriculture enabled people to produce surplus food. They could use this extra food when crops failed or trade it for other goods. Food surpluses allowed people to work at other tasks unrelated to farming. Agriculture kept formerly nomadic people near their fields and led to the development of permanent villages.
How many acres of corn do farmers plant?
U.S. industrial farmers may plant a thousand acres of just corn. The practice of specializing in a single crop is known as monoculture.

How did agriculture contribute to the rise of civilizations?
Start of Agriculture. Over centuries, the growth of agriculture contributed to the rise of civilizations. Before agriculture became widespread, people spent most of their lives searching for food—hunting wild animals and gathering wild plants.
When did farms become electrified?
By 1960, most farms in the U.S. and other developed countries were electrified. Electricity lit farm buildings and powered such machinery as water pumps, milking machines, and feeding equipment. Today, electricity controls entire environments in livestock barns and poultry houses.
Where did agriculture originate?
The earliest civilizations based on intensive agriculture arose near the Tigris and Euphrates Rivers in Mesopotamia (now Iraq and Iran) and along the Nile River in Egypt. Improved Technology. For thousands of years, agricultural development was very slow. One of the earliest agricultural tools was fire.
What is life science?
Life science is an enormous field of study that examines every living thing on earth. From bacteria to begonias to beluga whales, life sciences aim to learn everything about life on this planet. Read on to learn more about this field and everything it encompasses.
How many different branches of life science are there?
Many life science researchers specialize in one class or organism, and some specialties such as zoology have even more subspecialties. There are more than thirty different branches of life sciences, but we’ll review some of the major branches here.
What is the term for the study of how organisms live?
This can include plants, animals, viruses and bacteria, single-celled organisms, and even cells. Life sciences study the biology of how these organisms live, which is why you may hear this group of specialties referred to as biology.
What is the difference between botany and zoology?
Whereas botany focuses on the plant kingdom, zoology looks at the animal kingdom. It looks at characteristics of different animals, including their behavior, breeding, migration patterns, habitats, and more. It also works to identify new species; of the estimated 8.7 million animal species on earth, we only know about 1.2 million species.
Why is marine biology important?
It studies different ocean ecosystems, food chains, botany, and more. Part of the reason marine biology is so important is that most current theories say that life on Earth began in our oceans. There are species still swimming that were around in the time of the dinosaurs.
What is the role of ecology in the environment?
Ecology. Ecology looks at the interactions between organisms and their environment. This can include topics like the food chain, parasitic and beneficial relationships, and relationships within species. Ecology also examines things like biodiversity, organism population numbers, and distribution of those organisms.
Why do paleontologists use fossils?
Paleontologists try to use dinosaur fossils to reverse-engineer how they lived, what they looked like, and even how they died.
What is the life science?
The life sciences are the branches of science that study living things. A scientist who works in the life sciences would be interested in learning more about plants, animals, human beings or microscopic organisms.
Why is biology considered a life science?
Because biology covers so many aspects important to life, many scientists consider biology and life sciences to be synonymous terms. In this lesson, you will be introduced to some of the different branches of the life sciences. If you find these fields interesting, you might want to consider one of them as a career.
What are the different branches of life sciences?
In this lesson, we looked at some of the different branches of the life sciences. We learned that zoology is the study of animals. Marine Biology is the study of organisms living in the oceans. Entomology is the study of insects. Botany is the study of plants, and microbiology is the study of microscopic organisms.
What is the study of microscopic organisms called?
This includes living things that are too small to be seen with the naked eye. The study of microscopic organisms is called microbiology . As you can see, the word is made up of ‘micro’ (meaning small) and biology, which is the study of life.
What is the study of bugs?
Are you a bug lover? Then entomology might be more your speed. Entomology is the study of insects. There are billions of bugs, so a career as an entomologist would never get boring. The study of insects is very important. Insects play roles in the transmission of certain diseases and the destruction of crops in farmer’s fields, and we can learn a lot from studying the behaviors of insects, which you already know if you ever owned an ant farm.

What is agricultural science?
Agricultural science is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences used in the practice and understanding of agriculture. It covers topics such as agronomy, plant breeding and genetics, plant pathology, crop modelling, soil science, entomology, production techniques and improvement, study of pests and their management, and study of adverse environmental effects such as soil degradation, waste management, and bioremediation.
Why is agriculture important?
Agriculture is both a cause of and sensitive to environmental degradation, such as biodiversity loss, desertification, soil degradation and global warming, all of which can cause decreases in crop yield. Genetically modified organisms are widely used, although some are banned in certain countries.
What were staple food crops?
Staple food crops were grains such as wheat and barley, alongside industrial crops such as flax and papyrus. In India, wheat, barley and jujube were domesticated by 9,000 BC, soon followed by sheep and goats. Cattle, sheep and goats were domesticated in Mehrgarh culture by 8,000–6,000 BC.
How does industrialized agriculture depend on fossil fuels?
Industrialized agriculture depends on fossil fuels in two fundamental ways: direct consumption on the farm and manufacture of inputs used on the farm. Direct consumption includes the use of lubricants and fuels to operate farm vehicles and machinery. Agriculture and food system share (%) of total energy.
How much of the world’s land is used for livestock production?
Livestock production occupies 70% of all land used for agriculture, or 30% of the land surface of the planet. It is one of the largest sources of greenhouse gases, responsible for 18% of the world’s greenhouse gas emissions as measured in CO 2 equivalents. By comparison, all transportation emits 13.5% of the CO 2.
How does agriculture increase yield?
Agriculture seeks to increase yield and to reduce costs. Yield increases with inputs such as fertilisers and removal of pathogens , predators, and competitors (such as weeds). Costs decrease with increasing scale of farm units, such as making fields larger; this means removing hedges, ditches and other areas of habitat.
How does agriculture affect the environment?
Agriculture is both a cause of and sensitive to environmental degradation, such as biodiversity loss, desertification, soil degradation and global warming, which cause decrease in crop yield. Agriculture is one of the most important drivers of environmental pressures, particularly habitat change, climate change, water use and toxic emissions. Agriculture is the main source of toxins released into the environment, including insecticides, especially those used on cotton. The 2011 UNEP Green Economy report stated that agricultural operations produced some 13 per cent of anthropogenic global greenhouse gas emissions. This includes gases from the use of inorganic fertilizers, agro-chemical pesticides, and herbicides, as well as fossil fuel-energy inputs.
