Which biogeochemical cycle does not include an atmospheric reservoir?

Back

Phosphorus cycle does not include an atmospheric reservoir.

Front

What is commensalism?

Back

A symbiotic relationship where one organism benefits and the other is neither helped nor harmed, exemplified by moss growing on a tree trunk.

What is an abiotic factor affecting a biotic component?

Back

An abiotic factor is a non-living chemical or physical part of the environment that affects living organisms, such as phosphorous content in soil affecting plant growth.

Front

If gross primary productivity is 5 gC/m²yr, and the producers need 1.5 gC/m²yr for their own respiration, what is the net primary productivity?

Back

3.5 gC/m²yr.

Define the phosphorus cycle.

Back

The biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere, without an atmospheric component.

Front

What is the difference between Gross Primary Production and Net Primary Production?

Back

Gross Primary Production is the total amount of energy captured by photosynthesis, while Net Primary Production is the energy available to consumers after accounting for the energy used by producers for respiration.

Front

What is the significance of abiotic factors in an ecosystem?

Back

Abiotic factors, such as temperature, water, and soil nutrients, influence the types of organisms that can survive and thrive in an ecosystem.
