Detailed explanation-1: -They are micro-organisms which consume the dead matter like fungi and some bacteria which cannot produce their own food and are heterotrophs or saprophytic in nature. Macro consumers are also called phagotrophs as they directly ingest the other animals or plants. They include carnivores, omnivores and herbivores.

Detailed explanation-2: -a. macroconsumers, mainly animals (herbivores, carnivores, and detritivores), which wholly or partly ingest other living organisms or organic particulate matter.

Detailed explanation-3: -Autotrophs are producers which include plants. Phagotrophs or heterotrophs are consumers who depend on plants and animals for their nutrition. Q. Assertion :Herbivores are also called as key industry animals because they convert plant matter into animal matter.

Detailed explanation-4: -Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers-plants or algae-and nothing else. For example, a grasshopper living in the Everglades is a primary consumer.

Detailed explanation-5: -Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.
