What is the relationship between primary productivity and biodiversity?

Back

Front

What is assimilation in the nitrogen cycle?

Back

Assimilation is the process where plants and animals take nitrogen in and incorporate it into their body.

Front

What factors influence biome distribution?

Back

Biome distribution is influenced by climate, soil type, and geographical features.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and supporting plant growth.

Front

Define ecological succession.
