Semester Recap and Review

Front

What is an energy pyramid?

Back

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

Front

What percentage of energy is typically transferred from one trophic level to the next?

Back

About 10 percent of energy is transferred from one trophic level to the next in an energy pyramid.

Front

What are producers in an ecosystem?

Back

Producers are organisms, like plants, that create their own food through photosynthesis and form the base of the energy pyramid.

Front

What role do herbivores play in an energy pyramid?

Back

Herbivores are primary consumers that eat producers and are the second level in the energy pyramid.

Front

What are carnivores in an energy pyramid?

Back

Carnivores are secondary or tertiary consumers that eat herbivores or other carnivores, occupying higher levels in the energy pyramid.

Front

What is a top predator?

Back

A top predator is an organism at the top of the food chain that has no natural predators and typically has the least amount of energy available.

Front

How does a decrease in abiotic resources affect an ecosystem?

Back

A decrease in abiotic resources, like water, typically leads to a decrease in population size within an ecosystem.

Front

What are variations in a species?

Back

Variations are the differences among individuals of the same species, such as different traits like bird beaks.

Front

What is a predator?

Back

A predator is an organism that hunts and eats other organisms (prey) for energy.

Front

What is prey?

Back

Prey is an organism that is hunted and eaten by predators.
