Question

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

Explanation:

Since the great hornbill and toucan eat the same food and live in the same habitat (rainforest), they compete for resources. Competition for limited resources can restrict the growth of the toucan population. Overlapping breeding seasons may not directly limit the population as much as resource - related factors. Bill coloration is more of an adaptation for survival rather than a limiting factor. Genetic variability is important for long - term survival but not a direct limiting factor in this context.

Answer:

D. competition
