The great hornbill and the toucan both eat the same fruit, insects, and nuts. they both live in the rainforest. their large bills function to get food and also as warning coloration. which of the following is a limiting factor to the toucan population? overlapping breeding seasons bill coloration genetic variability competition

A limiting factor to the toucan population is competition.

Competition is an interaction between organisms in which the organisms contend emulously for the same resource such as food and territory. From the question, the great hornbill and the toucan have the same adaptation (large bills to get food and warning coloration), eat the same food (fruit, insects, and nuts), and they both live in the same habitat (rainforest). Competition would be a limiting factor to the toucan population as the two organisms will compete for food and habitat.
