Lesson 16: Energy Flow

Front

What is an energy pyramid?

Back

An energy pyramid represents the amount of energy available to the next 'feeder' in a food web.

Front

What are producers in a food web?

Back

Producers are organisms that create their own food, typically through photosynthesis, such as phytoplankton and seaweed.

Front

What is the primary source of energy for most ecosystems?

Back

The primary source of energy for most ecosystems is sunlight.

Front

How much energy is typically lost as heat or used by organisms at each trophic level?

Back

Typically, 90% of energy is lost as heat or used by organisms at each trophic level.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy from one level to the next.

Front

Which organisms have the most energy available in an energy pyramid?

Back

Producers have the most energy available in an energy pyramid.

Front

What is the role of herbivores in a food web?

Back

Herbivores are organisms that eat plants and are primary consumers in a food web.

Front

What is the difference between carnivores and herbivores?

Back

Carnivores eat other animals, while herbivores eat plants.

Front

What happens to energy as it moves up the food chain?

Back

As energy moves up the food chain, it decreases due to energy loss at each trophic level.

Front

What is the significance of the base of the energy pyramid?

Back

The base of the energy pyramid consists of producers, which capture energy from the sun and provide it to the rest of the ecosystem.
