Question

The kelp forest ecosystem is full of interactions among organisms. Large heterotrophs such as sea otters feed on small heterotrophs such as sea urchins. The sea urchins feed on large algae called giant kelp, which are autotrophs.
Which living thing in the kelp forest ecosystem releases oxygen through photosynthesis?
Sea Urchins
Kelp
Sea Otters
Small Heterotrophs

Answer 1

In the kelp forest ecosystem, the living thing that releases oxygen through photosynthesis is **kelp**. Kelp, being an autotroph, photosynthesizes and produces oxygen as a byproduct of this process.
