Envirothon Wildlife

Front 1

abiotic

Back 1

Non-living factor in an environment; for example, light, water, temperature, or rocks.

Front 2

acid rain

Back 2

Rain, snow, or other forms of water that are made more acid by the waste gases that come mainly from the burning of coal
and oil products. The gases (usually sulfur dioxide and oxides of nitrogen) mix with water and other materials in the air. Acid
rain falls on the land and water, and can affect wildlife, plants, soil, and building materials.

acorn

Back 3

the fruit of an oak tree; single seeded; popular wildlife food

Front 4

adapted, adaptation

Back 4

The process of making adjustments to the environment. For example, plants grow only where soil types, moisture, and
sunlight are balanced to the proper degree. Desert plants have adapted so they live under intense sunlight, on poor quality
soils, and with a much reduced water supply.

Front 5

aerate, aeration

Back 5

To supply with air or oxygen; to loosen the soil to add air space to it; to supply running water with additional oxygen, as when
a stream runs over falls or rapids or when wind creates waves on a lake.
