Question

What resource are pioneer species denied when other plants begin to crowd them out?

a - space
b - water
c - sunlight
d - oxygen

Answer 1

I think it’s
B: Water
Since common Pioneer species are bacteria, fungi, and lichens. Pioneer species usually have the ability to live in harsh environments where other species could not. Fungi can survive without sunlight or oxygen. I was searching up for the space one, but then it says that Fungi couldn’t survive without water, so I think that’s the answer.
