Which of the following activities is essential for animal survival?

The consumption of other living organisms is essential for the survival of many animals. As heterotrophic organisms, animals rely on the energy and nutrients they obtain from their food to grow, maintain bodily functions, and reproduce.

While some animals have evolved to consume only plants, others feed on herbivores or carnivores, depending on their adaptations and ecological niche. For example, carnivorous animals possess sharp teeth and claws to capture and consume prey, while herbivorous animals have flat molars to grind down tough plant material.

Omnivorous animals have adapted to consume both plant and animal matter, allowing them to utilize a broader range of food sources. Ultimately, the type of organisms that an animal consumes depends on its physiological adaptations and ecological role within its habitat.
