Food Chains and Food Webs

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, starting from producers to various levels of consumers.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, illustrating how different organisms are related through feeding relationships.

Front

What are producers in a food chain?

Back

Producers are organisms, typically plants, that create their own food through photosynthesis and serve as the base of the food chain.

Front

What are consumers?

Back

Consumers are organisms that cannot produce their own food and rely on consuming other organisms for energy. They can be classified as primary, secondary, or tertiary consumers.

Front

What are decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter, returning nutrients to the soil and completing the nutrient cycle.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers; they are typically herbivores.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers; they can be carnivores or omnivores.

Front

What is a tertiary consumer?

Back

A tertiary consumer is an organism that eats secondary consumers; they are often top predators in the food chain.

Front

What role do herbivores play in a food chain?

Back

Herbivores are primary consumers that feed on plants (producers) and are essential for transferring energy from producers to higher trophic levels.

Front

What role do carnivores play in a food chain?

Back

Carnivores are consumers that eat other animals, playing a crucial role in controlling the population of other species and maintaining ecosystem balance.
