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, starting with a primary producer and ending with a top predator.

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.

What are primary producers?

Back

Primary producers are organisms, such as plants and algae, that can make their own food through photosynthesis, forming the base of the food chain.

Front

What are consumers?

What is an autotroph?

Back

An autotroph is an organism that can produce its own food from inorganic substances, typically through photosynthesis or chemosynthesis.

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and must consume other organisms for energy.

What is an invasive species?

Back

An invasive species is a non-native organism that, when introduced to a new ecosystem, disrupts the local environment and can outcompete native species.
