69 points! Pls tell me where to put the star I will mark brainliest but If ur answer is unrelated I will report u. Place the STAR on the pioneer species.

umm It prolly is the second one since it look like the ones on G00GLE

Explanation:

Don't take my word

I believe it is the moss on the ground because moss can grow quickly and since a pioneer species is the first thing that came, it colonized first, like a pioneer. Have a nice day :)

Explanation:

My guess is that you're wanting the formula for respiration (which is basically the opposite of the formula for photosynthesis)?
So on the left (reactant/inputs) side should be: sugar and oxygen
On the right (products/outputs) side should be:
Carbon dioxide, water, light energy/ATP
