Producers uke this plant take in oxygen and release carbon dioxide during
just like animals and other living things
A) decomposition
B) photosynthesis
C) transformation
D) cellular reconstruction

I think B)

Explanation:

What your asking isn't that clear but if you said 'producers' is a kind of plant that creates their own food and the process is called photosynthesis.

But at the same time your question says "this plant take in oxygen and release carbon dioxide during  just like animals and other living things" Im not sure that plants are the ones to take in oxygen and release carbon dioxide so

I'm sorry if this didn't answer your question.

1. what is the relationship between the shape of an enzyme and the reactions they catalyze?

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )
