Unit 1 - Cycling of Ecological Energy REVIEW

Front

What is a population in ecology?

Back

A population refers to several members of the same species living in a given area.

Front

What is the primary source of energy for most ecosystems?

Back

The primary source of energy for most ecosystems is the sun.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem.

Front

What role do producers play in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

What is a consumer in an ecological context?

Back

A consumer is an organism that obtains energy by feeding on other organisms.

Front

What is the difference between herbivores, carnivores, and omnivores?

Back

Herbivores eat plants, carnivores eat other animals, and omnivores eat both plants and animals.

Front

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

Back

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

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment.

Front

How does an increase in prey population affect predator populations?

Back

An increase in prey population typically leads to an increase in predator populations due to more available food.
