Question

cycling of matter and energy quick check
what is the relationship between matter and energy in an ecosystem? (1 point)
matter and energy can only be modeled through food webs.
matter and energy are cycled through the ecosystem.
there is no relationship between matter and energy in an ecosystem.
matter and energy show the feeding relationships in an ecosystem.

Explanation:

In ecosystems, matter (like nutrients) is recycled through biogeochemical cycles, while energy flows through the system but is also transferred and transformed as part of ecological processes. The correct option reflects this core dynamic. Other options are incorrect: matter/energy can be modeled in other ways besides food webs, they have a clear functional relationship, and feeding relationships are only one aspect of their interaction, not their defining relationship.

Answer:

Matter and energy are cycled through the ecosystem.
