What type of evidence would you look for in a natural setting to indicate that there is competition taking placle among the plan
alexdok [17]

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.
