Front

What percentage of energy is typically used by organisms for survival at each trophic level?

Back

Typically, only 10% of the energy is used by organisms for survival at each trophic level.

Front

What is a herbivore?

Back

A herbivore is an organism that primarily eats plants. An example of a herbivore is a cricket.

Front

If there are 1000 Kcal available in the producers, how much energy is available in the herbivores?

Back

If there are 1000 Kcal available in the producers (trophic level 1), then 100 Kcal is available in the herbivores (trophic level 2).

Front

Which organisms provide energy to an owl?

Back

An owl receives energy from organisms such as mice and rabbits.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow.

Front

Define Trophic Level.

Back

Front

What role do Decomposers play in an ecosystem?

Back

Decomposers break down dead organic material, returning nutrients to the soil and making them available for producers.

Front

Explain the concept of an Energy Pyramid.

Back

An energy pyramid illustrates the energy flow in an ecosystem, showing how energy decreases at each trophic level.
