Food Chain, Food Web and Ecological Pyramid

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how different organisms are related through feeding relationships.

Front

What is an ecological pyramid?

Back

An ecological pyramid is a graphical representation that shows the relative amounts of energy or biomass at each trophic level in an ecosystem.

Front

What are producers in an ecosystem?

Back

Producers are organisms, like plants, that produce their own food through photosynthesis and form the base of the food chain.

Front

What are herbivores?

Back

Herbivores are organisms that primarily eat plants and are the primary consumers in a food chain.

Front

What are carnivores?

Back

Carnivores are organisms that primarily eat other animals and can be secondary or tertiary consumers in a food chain.

Front

What are omnivores?

Back

Omnivores are organisms that eat both plants and animals, playing a versatile role in the food web.

Front

What is the 10% rule in energy transfer?

Back

The 10% rule states that only about 10% of the energy from one trophic level is transferred to the next level in a food chain.

Front

What is an apex predator?

Back

An apex predator is a predator at the top of a food chain that has no natural enemies.

Front

What is competition in an ecosystem?

Back

Competition occurs when two or more organisms vie for the same resources, such as food, space, or mates.
