Quick Answer: When Dead Plants Decompose And Nitrogen Is Returned To The Soil The Interaction Is Between Which Two Spheres?

Explanation: When nitrogen is returned to the soil when dead plants decompose, the interaction is between geosphere and biosphere.

Which nitrogen is returned to the soil when dead plants decompose?

The plant may be eaten by an animal, and its biomass used to produce animal protein. Decomposers break down the bodies of dead organisms, urine and faeces resulting in nitrogen being returned to the soil as ammonia. This ammonia is converted to nitrates by nitrifying bacteria.

When plants draw nutrients from the soil the interaction is between which two spheres *?

Correct answer: Plants (biosphere) draw water (hydrosphere) and nutrients from the soil and release water vapor into the atmosphere. Explanation: Four spheres are all independent parts of a system.

When plants take carbon dioxide from the air which two spheres are interacting?

1. The pot plant ( biosphere ) absorbs water (hydrosphere) through its roots and uses it for photosynthesis. 2. The plant (biosphere) uses carbon dioxide (atmosphere) and gives off oxygen (atmosphere) during photosynthesis.

When nitrogen is returned to the soil?

Nitrogen is returned to the atmosphere by the activity of organisms known as decomposers. Some bacteria are decomposers and break down the complex nitrogen compounds in dead organisms and animal wastes. This returns simple nitrogen compounds to the soil where they can be used by plants to produce more nitrates.

Are dead plants part of the biosphere?

The biosphere benefits from this food web. The remains of dead plants and animals release nutrients into the soil and ocean. These nutrients are re-absorbed by growing plants. This exchange of food and energy makes the biosphere a self-supporting and self-regulating system.

How biosphere is formed?

The biosphere is postulated to have evolved, beginning with a process of biopoiesis (life created naturally from non-living matter, such as simple organic compounds) or biogenesis (life created from living matter), at least some 3.5 billion years ago.

When plants draw nutrients from the soil?

Plants draw water and dissolved nutrients up from the soil through their roots, and control where they go throughout the plant by opening and closing those tiny stomata. The sticky nature of water molecules moves nutrients throughout the plant, but plants cannot live on air and water alone.

What is the interaction between biosphere and atmosphere?

Biosphere-Atmosphere Interactions focuses on the sources and sinks of greenhouse gases (GHGs), air pollutants, particulate matter, water, and energy between the Earth’s surface and the atmosphere.

What is the interaction between atmosphere and hydrosphere?

All the spheres interact with other spheres. For example, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere).

How does biosphere depend on the atmosphere and hydrosphere to survive?

For instance, plants (biosphere) grow in the ground (geosphere), but to survive they absorb water (hydrosphere) and carbon dioxide (atmosphere). Nor are plants merely absorbing: they also give back oxygen to the atmosphere, and by providing nutrition to animals, they contribute to the biosphere.

What are the 4 spheres of the earth?

These four subsystems are called “spheres.” Specifically, they are the “lithosphere” (land), “hydrosphere” (water), “biosphere” (living things), and “atmosphere” (air). Each of these four spheres can be further divided into sub-spheres.

When plants take in carbon dioxide the interaction is between the atmosphere and what?

One of the first things taught in biology class is that animals breathe in oxygen and exhale CO2, while plants take in CO2 during the day and release oxygen. In a process called “photosynthesis,” plants use the energy in sunlight to convert CO2 and water to sugar and oxygen.

When plants absorb and incorporate nitrogen into the soil?

Plants take up nitrogen compounds through their roots. Animals obtain these compounds when they eat the plants. When plants and animals die or when animals excrete wastes, the nitrogen compounds in the organic matter re-enter the soil where they are broken down by microorganisms, known as decomposers.

How do plants get nitrogen from the soil?

Plants cannot themselves obtain their nitrogen from the air but rely mainly on the supply of combined nitrogen in the form of ammonia, or nitrates, resulting from nitrogen fixation by free-living bacteria in the soil or bacteria living symbiotically in nodules on the roots of legumes.

How do plants use nitrogen?

Nitrogen in Plants Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins.
