BIOGEOCHEMICAL CYCLES

Front

What are Green House gases?

Back

Gases such as carbon dioxide that trap heat in the Earth's atmosphere, contributing to global warming.

Front

Why do living things need nitrogen?

Back

To make proteins and amino acids.

Front

What is transpiration?

Back

The process of plants losing water through their leaves.

Front

What happens when one animal consumes another?

Back

Energy is transferred through the food chain.

Front

What is photosynthesis?

Back

The process that takes carbon dioxide from the air and converts it into a form of carbon used by living things.

Front

What is the water cycle?

Back

The continuous movement of water on, above, and below the surface of the Earth.

Front

Define biogeochemical cycles.

Back

Natural processes that recycle nutrients in various chemical forms from the non-living environment to living organisms and back.

Front

What role do decomposers play in biogeochemical cycles?

Back

Decomposers break down dead organic matter, returning nutrients to the soil.

Front

What is nitrogen fixation?

Back

The process of converting nitrogen gas from the atmosphere into ammonia, which can be used by plants.

Front

Explain the carbon cycle.

Back

The series of processes by which carbon compounds are interconverted in the environment, including photosynthesis and respiration.
