In a study, competition among plants
are normal. Hence, all plants required a few basic elements like the light,
water, nitrogen, or phosphorus, depending upon the species and the location. Evidence
that can conclude that competition do really happen in plants is that some plants
release toxins into the soil, in their dropped leaves which wipe out the competition
for soil nutrients (such as weeds). And when it come an area with many trees in
close proximity such as a forest, height is also indicative of competition for
light.
OK First we need to eliminate 2 answers which would be A and C
that leaves B and D
I believe the correct answer is D
because it explores all of the relationships of the food web as to just one.
hope this helps
