Lesson 16: Energy Flow

Front

What are producers in an energy pyramid?

Back

Producers are organisms that create their own energy through photosynthesis, such as plants. They form the base of the energy pyramid.

Front

What is the primary source of energy for all life on Earth?

Back

The primary source of energy for all life on Earth is the Sun.

Front

What percentage of energy is typically passed on to the next trophic level?

Back

Only about ten percent of the energy stored in an organism can be passed on to the next trophic level.

Front

What happens to the remaining energy that is not passed on to the next trophic level?

Back

The remaining energy is typically converted to heat and lost.

Front

What is a tertiary consumer?

Back

A tertiary consumer is an organism that eats secondary consumers. They are typically at the top of the food chain.

Front

Give an example of a primary consumer.

Back

An example of a primary consumer is a herbivore, such as a rabbit, that eats plants.

Front

What role do carnivores play in an energy pyramid?

Back

Carnivores are consumers that eat other animals and are typically found at higher trophic levels in the energy pyramid.

Front

How do herbivores obtain energy?

Back

Herbivores obtain energy by consuming plants, which are producers.

Front

What is the energy flow in a food web?

Back

Energy flows from producers to primary consumers, then to secondary consumers, and finally to tertiary consumers.

Front

What is the significance of the energy pyramid?

Back

The energy pyramid illustrates the distribution of energy among trophic levels in an ecosystem.
