Which statement best explains the ecological role of vultures?

Correct answer: They clean by feeding on dead animals

The direct answer is D: They clean the environment by feeding on dead animals. Vultures are scavenging birds. They usually feed on carcasses rather than hunting healthy animals or producing food. Their feeding removes dead organic matter quickly, reduces the spread of some disease-causing organisms and returns nutrients to the ecosystem through decomposition. Option D is correct because it identifies this cleaning and recycling role. Option A is wrong because pollination is mainly performed by insects, birds, bats and other pollinators, not the defining role of vultures. Option B is wrong because vultures do not graze on grass like herbivores. Option C is wrong because producers are green plants and some other organisms that make food, whereas vultures are consumers. Vultures are scavengers, not top producers; “top” also does not make sense for food-making organisms. Memory cue: vulture means scavenger—dead animals become nutrients instead of remaining as dangerous waste.
