Food Chains, Food Webs, & Energy Pyramids 2022

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 in an ecosystem, illustrating how different organisms are related through feeding relationships.

Front

What are producers in an ecosystem?

Back

Producers are organisms, typically plants and algae, that can make their own food through photosynthesis, forming the base of the food chain.

Front

What are primary consumers?

Back

Primary consumers are herbivores that eat producers (plants) and are the second level in a food chain.

Front

What are secondary consumers?

Back

Secondary consumers are carnivores or omnivores that eat primary consumers and are the third level in a food chain.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy at different trophic levels in an ecosystem, illustrating how energy decreases as it moves up the pyramid.

Front

What happens to energy as it moves up trophic levels?

Back

As energy moves up trophic levels, it decreases due to energy loss through metabolic processes, with only about 10% of the energy being transferred to the next level.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and completing the nutrient cycle in an ecosystem.

Front

What is the significance of arrows in a food chain diagram?

Back

The arrows in a food chain indicate the direction of energy flow, showing how energy is transferred from one organism to another.

Front

What might happen if a top predator is removed from an ecosystem?

Back

If a top predator is removed, it can lead to an increase in the population of primary and secondary consumers, which may result in overgrazing or depletion of producers.
