Why do the cells in all living things need energy?

Ato fuel their chemical reactions
Bto help them decompose
Cto communicate with other cells
Dso they can block sunlight

Verified Answer :

A. to fuel their chemical reactions

How would energy help them decompose? And how would it help them communicate with other cells? Even better, the cell doesn't NEED to communicate to other cells. And they don't need to block sunlight, and in-fact kind of need it. So the only common sense answer I can think of is A.

Answer:

a. to fuel their chemical reactions

Explanation:

Cells aren't meant to decompose things, there's no reason for them to communicate with other cells, and cells blocking sunlight just doesn't make much sense.

I hope this helps! :D
