Biology Review Part 2 Fall 2024

Front

What is the role of producers in an energy pyramid?

Back

Producers convert solar energy into chemical energy through photosynthesis.

Front

What are light-dependent reactions in photosynthesis?

Back

The part of photosynthesis when light energy is captured and transferred to a molecule, such as ATP.

Front

What effect does burning fossil fuels have on the carbon cycle?

Back

It adds carbon dioxide to the atmosphere.

Front

Which organisms convert nitrogen gas into a usable form for plants?

Back

Nitrogen-fixing bacteria.

Front

What process takes carbon dioxide out of the atmosphere?

Back

Photosynthesis.

Front

Define photosynthesis.

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is an energy pyramid?

Back

A graphical representation of the energy flow in an ecosystem, showing the energy available at each trophic level.

Front

What is the significance of nitrogen-fixing bacteria?

Back

They convert atmospheric nitrogen into ammonia, which plants can use for growth.

Front

Explain the light-independent reactions of photosynthesis.

Back

These reactions, also known as the Calvin cycle, use ATP and NADPH produced in light-dependent reactions to convert carbon dioxide into glucose.

Front

What is cellular respiration?

Back

The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
