Biology semester 1 final review

Front

What is an apex predator?

Back

An apex predator is a predator at the top of a food chain, with no natural predators of its own. Example: Hawk.

Front

What is the approximate efficiency of energy transfer between trophic levels?

Back

The efficiency of energy transfer from one trophic level to the next is roughly 10%.

Front

Which trophic level has the most energy?

Back

The 1st level - producers have the most amount of energy in a food chain.

Front

What should you do if you break glass in the lab?

Back

You should tell the teacher immediately.

Front

What is an abiotic factor?

Back

An abiotic factor is a non-living component of an ecosystem. Example: Water.

Front

Define producers in an ecosystem.

Back

Producers are organisms that produce their own food through photosynthesis or chemosynthesis. Example: Plants.

Front

What are primary consumers?

Back

Primary consumers are organisms that eat producers. Example: Herbivores like rabbits.

Front

What are secondary consumers?

Back

Secondary consumers are organisms that eat primary consumers. Example: Carnivores like snakes.

Front

What are tertiary consumers?

Back

Tertiary consumers are organisms that eat secondary consumers. Example: Apex predators like hawks.

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.
