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 that illustrates how different organisms in an ecosystem are related through feeding relationships.

Front

What are producers?

Back

Producers, also known as autotrophs, are organisms that can make their own food through photosynthesis or chemosynthesis, forming 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 herbivores, carnivores, or omnivores.

Front

What are decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter, recycling nutrients back into the ecosystem.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the distribution of energy among trophic levels in an ecosystem, with producers at the base and top predators at the top.

Front

What is a trophic level?

Back

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

Front

What is the role of the sun in a food chain?

Back

The sun is the primary source of energy for most food chains, providing the energy that producers use to create food through photosynthesis.

Front

What is the difference between herbivores and carnivores?

Back

Herbivores are animals that eat plants, while carnivores are animals that eat other animals.

Front

What is an omnivore?

Back

An omnivore is an organism that eats both plants and animals, allowing it to occupy multiple trophic levels.
