Trophic Levels and Energy Pyramids

Front

What does biomass refer to?

Back

Amount of living tissue at the trophic level.

Front

If there is 1000 Kcal available in the producers in trophic level 1, how much energy is available in the herbivores in trophic level 2?

Back

100 Kcal.

Front

Which animal is considered the apex predator?

Back

Hawk.

Front

In a marine food pyramid, between which two levels is the greatest amount of energy transferred?

Back

U and T.

Front

Which animal is a predator to a mouse but not an apex predator?

Back

Snake.

Front

Define trophic level.

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and nutrients.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation showing the flow of energy at each trophic level in an ecosystem.

Front

What is the primary source of energy for producers?

Back

Sunlight.

Front

Explain the concept of energy transfer in trophic levels.

Back

Energy transfer between trophic levels is inefficient, with only about 10% of energy being passed to the next level.

Front

What role do herbivores play in an ecosystem?

Back

Herbivores are primary consumers that feed on producers, transferring energy from plants to higher trophic levels.
