SC.912.L.17.9 -- Food Webs, Energy Pyramids, and Energy Flow

Front

What is a decomposer?

Back

A decomposer is an organism that breaks down dead organic material, returning nutrients to the ecosystem. Common examples include bacteria and fungi.

Front

What do the arrows in a food chain represent?

Back

The arrows in a food chain represent the flow of energy from one organism to another.

Front

Which level of the energy pyramid contains the most energy?

Back

The producer level contains the most energy.

Front

What are producers in an ecosystem?

Back

Producers are organisms that create their own food through photosynthesis, such as plants.

Front

What is the role of herbivores in a food web?

Back

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

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 energy flow in an ecosystem?

Back

Energy flow refers to the transfer of energy from one trophic level to another in an ecosystem, starting from producers to various consumers.

Front

Define commensalism.

Back

Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers recycle nutrients back into the soil, making them available for producers and maintaining ecosystem health.

Front

What are carnivores?

Back

Carnivores are organisms that primarily eat other animals and are typically found at higher trophic levels in a food web.
