Q: Because all animals require an external source of what, they are called heterotrophic? Read this paragraph and choose the correct option from the provided answers: 27.1 | Features of the Animal Kingdom By the end of this section, you will be able to: List the features that distinguish the kingdom Animalia from other kingdoms Explain the processes of animal reproduction and embryonic development Describe the roles that Hox genes play in development Even though members of the animal kingdom are incredibly diverse, most animals share certain features that distinguish them from organisms in other kingdoms. All animals are eukaryotic, multicellular organisms, and almost all animals have a complex tissue structure with differentiated and specialized tissues. Most animals are motile, at least during certain life stages. All animals require a source of food and are therefore heterotrophic, ingesting other living or dead organisms; this feature distinguishes them from autotrophic organisms, such as most plants, which synthesize their own nutrients through photosynthesis. As heterotrophs, animals may be carnivores, herbivores, omnivores, or parasites (Figure 27.2ab). Most animals reproduce sexually, and the offspring pass through a series of developmental stages that establish a determined and fixed body plan. The body plan refers to the morphology of an animal, determined by developmental cues. Choices: - fuel - energy - water - food A:
