Question

Parrotfish live in the ocean and eat plantlike organisms called algae. Sunlight is shining

on the fish and the algae.
is carbon moving into the living things, moving out of the living things, or both?
Carbon is moving into and out of the living things, at the same time.
Carbon is only moving into the living things; it is not moving out of them.
Carbon is only moving out of the living things, it is not moving into them.
There is no way to know for sure, with this information.
