What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how energy and nutrients flow between different organisms.

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients move from one organism to another in an ecosystem, typically starting with a producer.

What is a producer in a food web?

Back

A producer is an organism, usually a plant, that can make its own food through photosynthesis and serves as the base of the food web.

What is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants) and is the first level of consumers in a food chain.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers and is the second level of consumers in a food chain.

Front

What role do decomposers play in a food web?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for producers.

Front

What happens to energy as it moves up the food chain?

Back

As energy moves up the food chain, it decreases at each trophic level due to energy loss through metabolic processes.

Front

What is the original source of energy in an ecosystem?

Back

The original source of energy in an ecosystem is the Sun, which provides energy for photosynthesis in plants.

Front

What might happen if a top predator is removed from a food web?

Back

If a top predator is removed, the population of primary and secondary consumers may increase, potentially leading to overgrazing of plants.

Front

What is an example of a primary consumer?

Back

An example of a primary consumer is a caterpillar, which eats plants.
