Ecology Review for Summative Assessment

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy at different trophic levels in an ecosystem, illustrating how energy decreases as it moves from producers to top predators.

Front

What are producers in an ecosystem?

Back

Producers are organisms, primarily plants and phytoplankton, that convert sunlight into energy through photosynthesis, forming the base of the energy pyramid.

Front

What role do herbivores play in an energy pyramid?

Back

Herbivores are primary consumers that eat producers. They obtain energy by consuming plants and are located above producers in the energy pyramid.

Front

What are carnivores in the context of an energy pyramid?

Back

Carnivores are secondary or tertiary consumers that eat herbivores or other carnivores, obtaining energy from the organisms they consume.

Front

What is the significance of the top predator in an energy pyramid?

Back

The top predator is at the highest trophic level in the energy pyramid and has the least amount of energy available, as energy diminishes at each level.

Front

How does energy flow in an ecosystem?

Back

Energy flows in one direction, starting from the sun to producers, and then to various levels of consumers, without being recycled.

Front

What is biomass in an energy pyramid?

Back

Biomass refers to the total mass of living organisms at each trophic level, with the greatest biomass typically found at the producer level.

Front

What is the original source of energy for an energy pyramid?

Back

The original source of energy for the energy pyramid is the sun, which provides the energy necessary for photosynthesis.

Front

Why are phytoplankton important in aquatic ecosystems?

Back

Phytoplankton are crucial as they are primary producers in aquatic ecosystems, forming the base of the food web and contributing to the energy pyramid.

Front

What happens to energy as it moves up the energy pyramid?

Back

As energy moves up the energy pyramid, it decreases due to energy loss at each trophic level, primarily through metabolic processes.
