AP BIOLOGY

Detailed explanation-1: -Top predators, also called apex predators, eat other consumers. Consumers can be carnivores (animals that eat other animals) or omnivores (animals that eat both plants and animals). Omnivores, like people, consume many types of foods. People eat plants, such as vegetables and fruits.

Detailed explanation-2: -A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.

Detailed explanation-3: -It is a way of classifying animals, plants, and fungi that eat other organisms in order to survive. The four levels in this food chain are primary consumers, secondary consumers, tertiary consumers, and finally decomposers or phytoremediators.

Detailed explanation-4: -All of the interconnected and overlapping food chains in an ecosystem make up a food web. Organisms in food webs are grouped into categories called trophic levels. Roughly speaking, these levels are divided into producers (first trophic level), consumers, and decomposers (last trophic level).
