Food Webs and Energy Pyramids

Front

What is a producer in a food web?

Back

A producer is an organism that can make its own food through photosynthesis or chemosynthesis, serving as the base of the food web.

Front

What is a food web?

Back

A food web is a diagram that shows the interconnected food chains in an ecosystem, illustrating how energy and nutrients flow between organisms.

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 role do primary consumers play in a food web?

Back

Primary consumers are organisms that eat producers (plants) and are the second level in the food web.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers, typically carnivores or omnivores.

Front

What is a top predator?

Back

A top predator is an organism that is at the top of the food chain and has no natural predators.

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 complex network of interconnected food chains.

Front

What is a decomposer?

Back

A decomposer is an organism that breaks down dead organic material, returning nutrients to the soil and completing the cycle of matter.

Front

How does energy transfer in an energy pyramid?

Back

Energy transfer in an energy pyramid decreases as you move up each trophic level, with only about 10% of energy being passed to the next level.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how an organism obtains its energy.
