Final answer:
A type III functional response in predators is a result of factors I and III only. This response is characterized by low prey consumption rates at low prey densities, followed by an exponential increase in consumption rate as prey density increases. At higher prey densities, the consumption rate levels off.
Step-by-step explanation:
A type III functional response in predators is a result of factors I and III only. In this type of functional response, predators exhibit low prey consumption rates at low prey densities, followed by an exponential increase in consumption rate as prey density increases. However, at higher prey densities, the consumption rate levels off due to factors such as handling time or prey saturation. This type of functional response is commonly observed when predators switch from actively searching for prey to more passive foraging behaviors.
