Insect herbivory is when insects consume plants or parts of a plant as their main food source. Interestingly, this term also applies to those insects who do not harm the plant, but consume the pollen, etc.
However, focusing on harmful insect herbivory, we can assume that in the presence of these insects a plant will have a hard time staying alive or mating effectively due to the damage caused. Therefore, we can assume that <u>the </u><u>plant </u><u>on the </u><u>left </u><u>will not be able to stay </u><u>competitive</u>.
