What is energy flow in an ecosystem?

Back

Energy flow refers to the transfer of energy from one organism to another through food chains and food webs, starting from producers to various levels of consumers.

What role do herbivores play in a food web?

Back

Herbivores are primary consumers that eat producers (plants) and transfer energy from the producers to higher trophic levels.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a linear sequence of organisms where each is eaten by the next, while a food web is a more complex network of interconnected food chains.

Front

What is a trophic level?

Back

A trophic level is a position in a food web or food chain that indicates the organism's role in the flow of energy, such as producers, primary consumers, and secondary consumers.

Front

What is a carnivore?
