What is a Trophic Level?

Back

A trophic level is a position in a food chain or food web that indicates the feeding relationships among organisms. It shows how energy and nutrients flow through an ecosystem.

What is a Producer?

Back

A producer is an organism that can make its own food through photosynthesis or chemosynthesis, typically plants and some bacteria.

Front

What is a Consumer?

Back

A consumer is an organism that eats other organisms for food. Consumers can be classified into primary, secondary, and tertiary consumers based on their position in the food chain.

Front

What is a Primary Consumer?

Back

A primary consumer is an organism that eats producers. They are usually herbivores, such as rabbits and deer.

Front

What is a Secondary Consumer?

Back

A secondary consumer is an organism that eats primary consumers. They can be carnivores or omnivores, such as foxes and some birds.

Front

What is a Tertiary Consumer?

Back

A tertiary consumer is an organism that eats secondary consumers. They are often at the top of the food chain, such as hawks and large cats.

Front

What is a Decomposer?

Back

A decomposer is an organism that breaks down dead or decaying organisms, returning nutrients to the soil. Examples include fungi and bacteria.

Front

What role do Herbivores play in an ecosystem?

Back

Herbivores are primary consumers that feed on plants (producers), playing a crucial role in transferring energy from producers to higher trophic levels.

Front

What role do Carnivores play in an ecosystem?

Back

Carnivores are consumers that eat other animals. They can be secondary or tertiary consumers, helping to control the population of other species.

Front

What is a Food Chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.
