Which is one way that the movement of matter through an ecosystem is different from the transfer of energy? A. Only the movement of matter involves living things.
B. Only the movement of matter flows in one direction only.
C. Only the movement of matter occurs in an unending cycle.
D. Only the movement of matter involves feeding relationships.

C. Only the movement of matter occurs in an unending cycle.

Explanation:

Living organisms require both energy and matter for their growth and development. Nutrients are the nonliving matter of an ecosystem. Matter in form of nutrients moves from the soil to the plants, which absorb them using their roots. Matter moves to organisms called consumers when they feed on the plants and themselves consecutively.

When these organisms die, the matter goes back to the soil and the cycle starts again. Energy, on the contrary, moves in one direction. However, only the movement of matter occurs in an unending cycle.

thinking it would be d not too sure but i think it's right

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
