Unit 1 - Ecology - Semester Review

Front

What are consumers in an ecosystem?

Back

Consumers are organisms that cannot produce their own food and must eat other organisms for energy.

Front

What is the role of producers in a food chain?

Back

Producers are the first organisms in a food chain that create their own food through photosynthesis, such as plants.

Front

What is the primary source of energy for all ecosystems?

Back

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

Front

What are decomposers and why are they important?

Back

Decomposers are organisms that break down dead material and recycle nutrients back into the ecosystem.

Front

What process do plants use to make their own food?

Back

Plants use the process of photosynthesis to convert sunlight into energy.

Front

Define 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 the difference between a food chain and a food web?

Back

A food chain is a simple linear path of energy flow, while a food web is a complex network of interconnected food chains.

Front

What are primary consumers?

Back

Primary consumers are organisms that eat producers; they are typically herbivores.

Front

What is the significance of trophic levels in an ecosystem?

Back

Trophic levels represent the different stages in a food chain, indicating the flow of energy and nutrients from producers to various levels of consumers.

Front

What role do scavengers play in an ecosystem?

Back

Scavengers are organisms that consume dead animals, helping to clean up the environment and recycle nutrients.
