Which of the following describes a facultative predator?
A lion hunting in a pride
A shark swimming in the ocean
A spider capturing insects in a web
A bear eating berries in the forest
Correct option (d)
A facultative predator is an organism that can shift from predator to non-predator based on food availability. A bear eating berries in the forest is an example of a facultative predator in this scenario because bears are omnivores and may feed on both plants and animals.
If the bear is unable to find enough berries, it may resort to hunting small creatures such as rats or fish.
A lion hunting in pride, on the other hand, is an example of an obligatory predator, as they must hunt and consume flesh to survive.
A shark in the ocean is also an obligatory predator because it feeds mostly on other species. Finally, a spider collecting insects in its web is an example of an obligatory predator, as it is a predator that needs on hunting prey to survive.
