Give four categories of consumers in an ecosystem and the role that each plays

What will be an ideal response?


Consumers can be divided into primary consumers (herbivores), omnivores, secondary consumers (carnivores), higher orders of consumers, and parasites. Primary consumers "feed directly on producers." "Animals that feed on primary consumers are called secondary consumers." Each level of consumer feeds on the level before. Higher-level consumers (like humans) may be found in several levels at the same time. Parasites may become "associated with another plant or animal and feed on it over an extended period of time." Each organism has a place in the food web, and such predator-prey relationships help to keep the ecosystem in balance.
