What are the processes involved in the movement of elements and compounds that make up nutrients within ecosystems?

Choose the correct option:

a) Biogeochemical cycles

b) Food chains

c) Both a and b

Answer:

Both a and b

Elements and compounds that make up nutrients move within ecosystems through biogeochemical cycles and food chains.

Biogeochemical cycles involve the recycling of elements such as carbon, nitrogen, and phosphorus between living organisms, the atmosphere, bodies of water, and the soil. For example, carbon dioxide is taken up by plants during photosynthesis and passed along the food chain as organisms consume one another.

Food chains play a crucial role in transferring nutrients from one organism to another as they are consumed. For instance, plants absorb nutrients from the soil, herbivores consume the plants, and then carnivores consume the herbivores, transferring nutrients along the chain.
