What is evaporation?

Back

Evaporation is the process by which water is heated and transformed from a liquid state into water vapor, typically due to heat from the sun.

What role does runoff play in the phosphorus cycle?

Back

Runoff brings phosphorus from land into waterways, contributing to the phosphorus cycle and affecting aquatic ecosystems.

Front

Why is the phosphorus cycle important?

Back

The phosphorus cycle is crucial because phosphorus is a key component of DNA, which is essential for all living organisms.

Front

What processes release carbon dioxide into the atmosphere?

Back

Cellular respiration and burning fossil fuels are two primary processes that release carbon dioxide into the atmosphere.

Front

How do animals obtain nitrogen for proteins and nucleic acids?

Back

Animals obtain nitrogen by consuming other living organisms, as they cannot create it themselves.

Front

Define biogeochemical processes.

Back

Biogeochemical processes are natural cycles that involve the movement of elements and compounds through biological, geological, and chemical systems.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water through evaporation, condensation, precipitation, and runoff.

Front

Explain the carbon cycle.

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms, involving processes like photosynthesis and respiration.

Front

What is transpiration?

Back

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

Front

What is the significance of nitrogen fixation?

Back

Nitrogen fixation is the process of converting atmospheric nitrogen into a form that plants can use, which is essential for plant growth and the nitrogen cycle.
