Adhesion

What does water do when it freezes?

Expand

The inward pulling of water molecules at the surface.

Tension

The process by which inorganic materials move from the atmosphere to soil, into living organisms and back again.

Biogeochemical Cycles

T/F During ammonification, bacteria convert nitrogen gas into ammonium compounds.

False

The only way water enters the atmosphere through biotic factors.

Transpriation

The cycle that photosynthesis and respiration are the base for.

Carbon Cycle

Convert nitrogen gas (N2) into ammonium compounds (NH4).

Nitrogen Fixation

The way of life of a species.

niche

The nonliving parts of the environment.

abiotic factors

An ecological unit that includes all the interacting parts of an environment in an area. Ex. a cave, a pond

ecosystem

biotic factors

The portion of Earth that sustains life The portion of Earth that sustains life. It extends from high in the atmosphere to the bottom of the oceans.

biosphere

These are autotrophic organisms that manufacture their own food

producers

This means that it must consume food to get energy.

Heterotroph

These heterotrophs can be classified into two main groups.

Primary and Secondary Consumers

This group of organisms break down dead tissue and animal wastes.
