Biology Unit 3 - Energy Flow (Concepts 1-3)

Front

What are trophic levels?

Back

Trophic levels are the hierarchical levels in an ecosystem, representing the flow of energy and nutrients from producers to various levels of consumers.

Front

How many trophic levels are there in a typical ecosystem?

Back

There are typically 5 trophic levels: producers, primary consumers, secondary consumers, tertiary consumers, and quaternary consumers.

Front

Which group has the smallest number of organisms in a food chain?

Back

The quaternary consumers have the smallest number of organisms in a food chain.

Front

What are anabolic reactions?

Back

Anabolic reactions are metabolic processes that build larger molecules from smaller ones and require energy.

Front

What is an example of an exothermic reaction?

Back

Combustion of fuels is an example of an exothermic reaction, where energy is released.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings.

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is an energy-carrying molecule that stores and transports chemical energy within cells.

Front

What role do producers play in an ecosystem?

Back

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

Front

What are primary consumers?

Back

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

Front

What are secondary consumers?

Back

Secondary consumers are organisms that eat primary consumers; they can be carnivores or omnivores.
