Animals are a more complex life form than plants. What did plants do that allowed for animal life to develop? * plants make oxygen which animals use to breathe
plants make carbon dioxide which animals use to breathe
plants make water which animals use to swim in
plants make sunlight which animals use to make vitamin D

I'm not sire if it's a single question answer but it looks like it's "A"

humans and animals make carbon dioxide which plants take in

plants don't make water, the water cycle "makes" it

and plants don't make vitamin D or sunlight

materials water oxygen those are the things i can think of in this moment.

doctors i believe if i'm wrong sorry
