What is a food web?

Back

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

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms where each one is eaten by the next in the chain, showing the flow of energy.

Front

What are producers?

Back

Producers are organisms, like plants, that create their own food using sunlight through a process called photosynthesis.

Front

What are consumers?

Back

Consumers are organisms that cannot produce their own food and must eat other organisms for energy.

Front

What are decomposers?

Back

Decomposers are organisms, like fungi and bacteria, that break down dead plants and animals, returning nutrients to the soil.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose (food) and oxygen.

Front

How do animals get energy?

Back

Animals get energy by consuming other organisms, either plants (herbivores) or other animals (carnivores).

Front

What happens if a key species is removed from a food web?

Back

If a key species is removed, it can disrupt the balance of the ecosystem, leading to population decreases or increases in other species.

Front

What role do herbivores play in a food web?

Back

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

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with each other and their physical environment.
