Front 1

Succession

Back 1

A somewhat predictable series of changes over time in a community.

Front 2

Primary Succession

Back 2

The somewhat predictable series of changes in a community that follows a disturbance severe that no vegetation of soil life remains.

Front 3

Secondary Succession

Back 3

The somewhat predictable series of changes in a community that follows a disturbance that dramatically alters the community but does not destroy all vegetation or soil life.

Front 4

Pioneer Species

Back 4

One of the first species to colonize newly exposed land.

Front 5

Carrying Capsity

Back 5

The largest population a given environment can support.

Front 6

Population density

Back 6

The number of individuals in a population per unit of area.

Front 7

Population Distribution

Back 7

How organisms are arranged within an area; sometimes called "population dispersion".

Front 8

Age Structure Diagram

Back 8

A chart that shows the age distribution of a population; also called "age distribution".

Front 9

Biome

Back 9

A grouping of ecosystems with similar abiotic and biotic conditions.

Front 10

Climatograph

Back 10

A diagram that's shows an area's average temperature and precipitation.

Front 11

Net-Primary Production

Back 11

The organic matter, or biomass, that remains after cellular respiration.

Front 12

Tropic Rain Forest

Back 12

A tropical woodland with an annual rainfall of at least 100 inches, and marked by lofty broad-leaved evergreen trees forming a continuous canopy.

Front 13

Tropic Dry Forest

Back 13

Diverse ecosystem consisting of deciduous trees which shed foliage in dry season.

Front 14

Deciduous

Back 14

A tree that loses its leaves and stops photosynthesis during part of the year.

Front 15

Savanna

Back 15

A grassy plain in Tropical and Subtropical regions with few trees.

Front 16

Desert

Back 16

A dry landscape that form regions that receive no precipitation.

Front 17

Temperate Rain Forest

Back 17

Woodland of a usually rather mild climate area with the temperature zone that receives heavy rainfall, including trees.

Front 18

Coniferous

Back 18

Tree bearing cones that typically do not lose its leaves.

Front 19

Temperate Forests

Back 19

Occur in areas where precipitation is spread relatively evenly throughout the year.

Front 20

Temperate Grassland

Back 20

Occur in areas with moderate seasonal precipitation, but hot enough to support large trees that are common to these forests.

Front 21

Chaparral

Back 21

Succulent thicknent-grasses and short fleshy plants, one of the earths major Biome.

Front 22

Boreal Forest

Back 22

A forest that grows in regions of the northern hemisphere with cold temperatures.

Front 23

Tundra

Back 23

A cold, treeless, Iceland area of far northern regions.

Front 24

Permafrost

Back 24

Thick subsurface layer of soil that femian frozen throughout the year, occurring in polar regions.

Front 25

Climate

Back 25

Weather conditions prevailing in and area generally, or over a long period of time.

Front 26

Weather

Back 26

The state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
