Front

Abiotic

Back

Non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.

Front

Biotic

Back

Living components of an ecosystem, such as plants and animals.

Front

Cycles of Matter

Back

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

Front

Water Cycle

Back

The continuous movement of water on, above, and below the surface of the Earth, involving processes such as evaporation, transpiration, condensation, and precipitation.

Front

Evaporation

Back

The process by which water changes from a liquid to a gas or vapor.

Front

Transpiration

Back

The process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.

Front

Condensation

Back

The process by which water vapor in the air is changed into liquid water.

Front

Precipitation

Back

Any form of water - liquid or solid - falling from the sky, including rain, sleet, snow, and hail.

Front

Carbon Cycle

Back

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

Front

Photosynthesis

Back

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