Biochemical Cycles Flashcard

Front

What do all living things need?

Back

Energy

Front

What is evaporation?

Back

The process of changing from a liquid to a gas, usually caused by energy from the sun.

Front

What is the main thing that carries out Nitrogen Fixation?

Back

Bacteria.

Front

What is Nitrogen Fixation?

Back

When nitrogen gas is turned into a form (nitrates) that plants and animals can use.

Front

What is condensation?

Back

The process of changing from a gas to a liquid, such as water vapor changing into water.

Front

What role do bacteria play in the nitrogen cycle?

Back

Bacteria are responsible for nitrogen fixation, converting nitrogen gas into usable forms for plants and animals.

Front

What is the significance of the water cycle in ecosystems?

Back

The water cycle is crucial for maintaining ecosystems, as it regulates water availability for plants and animals.

Front

How does energy from the sun affect evaporation?

Back

Energy from the sun provides the heat necessary for liquid water to change into water vapor during evaporation.

Front

What are nitrates and why are they important for plants?

Back

Nitrates are a form of nitrogen that plants can absorb and use for growth and development.

Front

What is the process of transpiration?

Back

Transpiration is the process by which water is absorbed by plant roots and then released as water vapor through pores in leaves.
