which of the following are false about ecosystems?

Question

1) chemical nutrients cycle within an ecosystem's structural web
b) the web of relationships within an ecosystem includes the nonliving components of the environment
c) in the process of energy conversions, energy is eventually converted to heat
d)bacteria and fungi recycle energy within an ecosystem
e)plant and other photosynthetic organisms are producers

Answer 1

False: B The food web deals with who eats whom.
D Energy is not recycled. Most of it goes off as useless heat. They recycle matter.

Answer 2

B. The ecosystem is about life. Except to the extent that the physical geography determines the rainfall, which helps to define the ecosystem (e.g., desert, rain forest, savannah, etc.), the nonliving components are not part of the ecosystem.

Answer 3

B.
C is not false because some of the energy is lost as heat, some enters into animals through plants, and then decomposers.

Answer 4

I have to say B.
Energy is eventually converted to heat because mammals use the energy to keep themselves warm.
