Question

All animals

Quizplus · Accepted Answer

All animals are heterotrophic, which means they cannot produce their own food and must obtain it from other sources. Option A is incorrect because animals have eukaryotic cells, which are more complex than prokaryotic cells. Option C is incorrect because only certain animals, such as insects and crustaceans, have cell walls made of chitin. Option D is incorrect because not all animals obtain food by absorption; some animals, such as carnivores, obtain food by actively hunting and ingesting prey.
