name the main nitrogen-containing compound found both in plants and in animals​

Answers

Answer:

Soil contains nitrifying bacteria that are crucial in converting nitrogenous wastes of dead and decaying matter of plants and animals to ammonia.

The most redox potential of soil nitrogen, ammonia, is transformed into its most oxidized form, nitrate, by nitrifying bacteria. By preventing soil nitrogen losses from leaching and nitrate denitrification, this is crucial for the function of the soil ecosystem.

What nitrogen compound found in plants and animals​?

The nitrifying bacteria found in soil are essential for producing ammonia from the nitrogenous waste products of dead and decaying plants and animals. The ammonia is subsequently changed into compounds that include ammonium. This is how the formation of ammonium compounds is aided by animals and plants.

Nitrification, which turns ammonia into nitrite and then nitrate, is a vital stage in the worldwide nitrogen cycle. Only prokaryotes perform aerobic nitrification, which makes up the majority of the process.

Therefore, The nitrifying bacteria found in soil are essential for producing ammonia from the nitrogenous waste products of dead and decaying plants and animals.

I think the height of the ramp affects the distance that the ball can go, but the size doesn't affect it

and as you decrease th height of the ramp it will look like straight thing, when it look like that the ball might need a little force in order to get speed also to go far

but in this condition the size can affect the ball distance it also depends on how much you give to it

Rocks , soil trees water air and life .How do all the parts affect each other? Give some
examples

Answers

Explanation:

Answer:

For the complete encyclopedic entry with media resources, visit: http://www.nationalgeographic.org/encyclopedia/weathering/

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.

For example, certain kinds of air pollution increase the rate of weathering. Burning coal, natural gas, and petroleum releases chemicals such as nitrogen oxide and sulfur dioxide into the atmosphere. When these chemicals combine with sunlight and moisture, they change into acids. They then fall back to Earth as acid rain.
