Which statement is an example of competition? a. egrets eat insects that are unearthed after livestock graze. b. wasps lay eggs inside hornworms so that after hatching the wasp larvae can feed on the hornworm. c. lions and hyenas, which both live in a savanna ecosystem, eat the same prey, antelope. d. otters contribute to a high level of diversity in their ecosystem as they eat urchins, allowing kelp to grow. e. ladybugs consume insects such as aphids, mealyworms, and spider mites

The correct answer would be option C.

Competition is a type of ecological interaction between organisms of the same or different species in which they compete with each other for the same resources.  

Examples of same resources may include territory, water, food (such as same prey), et cetera.

Similarly, in option C, lions and hyenas live in the same ecosystem and consume the same prey. Thus, the interaction between lion and hyenas is competition.
