Answer

Why do plants need air to make food?

The two primary reasons plants need is air to photosynthesize (make food) and to breathe. Plants need to breathe for the same reason people and animals must breathe – they need oxygen to convert food into energy.

What happens to the energy used in agriculture?

A part of the direct, indirect and solar energy used in agriculture is transformed into produce storing it as chemical energy. The rest of the energy is wasted. In the case of direct energy, it is wasted as heat of the machinery used, indirect energy is wasted as fertilizers and pesticides miss their target.

How does farming affect the atmosphere?

Some activities and equipment on farms release pollutants into the atmosphere. The Air Monitoring at Agricultural Operations site explains how EPA works to study these emissions and the federal standards that limit emissions. It also describes common practices that can be used to reduce emissions from crop and animal farms.

How are ambient air emissions from farming practices regulated?

The degree to which ambient air emissions from farming practices — such as prescribed burning — are allowed are location-specific (specific to a geographic area) within each State Implementation Plan. Visibility standards may also apply through the State Implementation Plan.

How is air useful in agriculture?

(b) Air speeds up drying up of agricultural products like grains, pulses fruits etc. Air helps in pollination of flowers and dispersel of seeds.


How is air useful in windmill?

Air helps in pollination of flowers and dispersel of seeds. c Windmills work where there is sufficient movement of air. d Air filled tyres of cars move smoothly on road as there is less friction.


How is air useful to scooters?

Air filled tyres of cars move smoothly on road as there is less friction.


What can wind be used for?

Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity. The terms “wind energy” and “wind power” both describe the process by which the wind is used to generate mechanical power or electricity.


What are 3 advantages of wind power?

Advantages of Wind PowerWind power is cost-effective. … Wind creates jobs. … Wind enables U.S. industry growth and U.S. competitiveness. … It’s a clean fuel source. … Wind is a domestic source of energy. … It’s sustainable. … Wind turbines can be built on existing farms or ranches.


How does air help in the moving of a boat?

The Wind inflates the sail and put pressure on the sail to make it move forward. When wind blows against the boat at an angle, it also inflates the sail, and it forms a foil shape, creating a difference in pressure that pushes the sail perpendicular to the wind direction. Hope this will help you.


What is the moving air called?

windAir is constantly moving around the earth. This moving air is called wind. Winds are created when there are differences in air pressure from one area to another.


How is water Vapour useful to us?

Water vapor is the most prevalent greenhouse gas. It causes roughly half of the warming of the planet. Like other greenhouse gases, it lets almost all of the sunlight reach the earth’s surface but absorbs heat radiated upward from the earth.


How can we reduce the potential for destructive wildfires and thus maintains long-term air quality?

reduce the potential for destructive wildfires and thus maintains long-term air quality. remove logging residues, control insects and disease, improve wildlife habitat and forage production, increase water yield, maintain natural succession of plant communities, reduce the need for pesticides and herbicides.


Who collaborated with farmers on the first-ever nationwide study of air emissions from animal feeding operations (AFOs)?

EPA collaborated with farmers on the first-ever nationwide study of air emissions from animal feeding operations (AFOs).


What is the EPA’s air quality standards?

Pursuant to Title I of the CAA, EPA has established national ambient air quality standards (NAAQSs) to limit levels of “criteria pollutants,” including: carbon monoxide, lead, nitrogen dioxide, particulate matter, ozone, and. sulfur dioxide. EPA calls these pollutants “criteria air pollutants” because the agency has regulated them by first …


Why is sulfur dioxide considered a criteria air pollutants?

EPA calls these pollutants “criteria air pollutants” because the agency has regulated them by first developing health-based criteria (science-based guidelines) as the basis for setting permissible levels. One set of limits (primary standard) protects health; another set of limits …


Is the EPA an active participant in the NAAQS?

The U.S. Department of Agriculture (USDA) has established the Agriculture Air Quality Task Force . EPA is an active participant in the Task Force.


Why do plants need air?

Air is needed for the roots primarily to allow the plants to breathe. If air is not available to the roots, it can cause the roots to fail. Root failure is a very common cause of plant stress, although often goes unnoticed because the roots are not available unless the plant is taken out of its container. Root failure is a major problem …


Why is it important to keep plants clean?

Keeping plant surfaces clean not only keeps them looking good aesthetically but also helps them perform better. In some interior spaces, air movement is highly limited, causing stagnant air to build-up. The lack of fresh air may be insufficient in oxygen or other gases needed by the plant.


What happens when a growing medium is compacted?

When a growing medium is compacted, air pockets are squeezed out and replaced with compacted soil. Soil compaction is common with aged growing mediums. Over time most organic soils decompose and decay, causing them to compact. The compaction squeezes out air from the soil, making sufficient are to the roots unavailable.


Why are roots denied air?

Roots are denied sufficient air when the soil does not allow for air. The two main causes of this are over-watering and soil decay. Soils that are heavily saturated with water have almost no air. When this happens, the roots cannot breathe, causing root failure.


Is air available to plants?

Air is often taken for granted as it is invisible and seems readily available to plants above ground. However, even though air is abundant in our atmosphere, there are factors that can disrupt the availability of fresh air to a plant.


How does the control of frost work?

This process involves flying back and forth in the warm air over the area to be protected and forcing this air down toward the ground. Usually only a small area can be protected because of the limited time available when a frost is occurring.


Can airplanes be used for tobacco?

The use of the airplane for applying various spras, granular or dust materials (predominantly insecticides) is now a common practice among Ontario’s flue-cured tobacco growers. Although the cost of application is often slightly higher than with ground equipment the airplane has been able to compete quite successfully. Possibly this is at least partially due to with which the job can be done as well as the prompt service. In addition, a surprisingly uniform and complete coverage of material can be obtained.
