Answer:
The wildflowers grow when there is nothing on the trees because the wildflowers have access to sunlight, but when the biotic trees grow and block the sun the wildflowers don't have access to the sun.
Explanation:
Biotic is all living things, and plants need sun to grow.
Hope this helped!! (also don't copy word for word please)
This was my answer on the test: A limiting factor of wildflowers on the forest floor is the sunlight. This affects the plant because the wildflowers cannot grow without sunlight and when the leaves block the sunlight it cannot grow.
Also... are you doing COA because I had the same question on my test?
