Shivani's Environmental Science Vocab Project--- Period 5

Categories of Species

Endangered species

A species at risk of extinction.

Indicator species

Certain types of species who can show the overall health of the ecosystem by either of their presence or absence because these species are very fragile.

Pioneer species

Species that establishes itself at the start of succession.

Threatened species

A species in the near future, most likelyto become an endangered species.

Levels of Organization

Organism

A living thing.

Population

How many of a living organism.

Community

A group of different organisms interacting with each other.

Ecosystem

A place where abiotic and biotic factors are interacting.

Biome

The geopraphic area with many ecosystem based on climate and elevation.

Biomes

Coniferous forest

Most of Canada is in this biome.

Desert

The Sahara Desert is the largest desert in the world.

Freshwater biome

Most of the freshwater in the world are in glaciers.

Grassland/ savannah

The middle of the United States is grassland.

Marine biome

Largest biome in the world.

Rainforest

Has the most biodiversity.

Temperate deciduous forest

The biome we live in.

Tundra

Has the least biodiversity.

Food System

Decomposer

An organism which breaks down other dead organisms.

Food chain

The transfer of energy from one organism to another in a one line chain.

Food web

The transfer of energy from one organism to another in a web like format.

Primary consumer

An animal that feeds on plants.

Producer

An organism which can produces its own food.

Secondary consumer

An animal which feeds on primary consumer.

Tertiary consumer

An animal which feeds on secondary consumers.

Trophic level

The class of organisms in a food chain or web.

Biodiversity

Abiotic factors

Are non- living things that never was living or will live.

Biotic factors

Living things that were once living or a piece of a living (or once living) thing.

Ecosystem biodiversity

The differences in ecosystems.

Genetic biodiversity

The differences in genes in the ecosystem.

Hotspots

Places on earth that are VERY biodiverse.

Species biodiversity

The difference in the plants and animals (organisms).

Categories of Succession

Ecological succession

It is the process in which communities of an ecosystem change over time.

Primary succession

When ecological succession takes place where an ecosystem NEVER existed., A climax community is the final stage of succession. The stage in which the ecosystem becomes stable (until disturbed.

Secondary succession

When ecological succession takes place where an ecosystem was disturbed., A climax community is the final stage of succession. The stage in which the ecosystem becomes stable (until disturbed.

Population

Carrying capacity

The number of individuals of a species that an ecosystem can support.

Exponential growth

A sudden explosion of population growth.

J-curve

Limiting factors

Events that help control population growth.

Population growth

How much the population has grown.

Population growth rate

How much the population will continue to grow in the years to come.

S-curve

Water pollution

Aquifier

An underground bed or layer of permeable rock, sediment, or soil that helps clean the water.

Desalination

Taking the salt out of saltwater and making it freshwater.

Erosion

The gradual wearing away of land.

Impermeable

Water can't get in it.

Inorganic pollutant

Example of these are heavy metals, ammoniea, and acidity.

Non-point source

Pollution that can not be pin pointed out and the pollution doesn't go directly into the water.

Organic pollutant

Example of these are: oil, degerant, and cosemetics.

Point Source

Pollution that can be pin pointed out and the polluion does go directly into the water.

Urbanization

To make an area more city-like.

Water pollution

"Damage" or "disturbance" in the Earth's water.

Water purification

A process to clean out the water or get rid of the pollution in the water.

Watershed

A drainage basin.

Wetlands

Areas like swamps, which are biodiverse and help a lot to purify our water.

Resources

Natural resources

Natural resources are natural things that people use from earth.

Non-renewable resources

Any material or energy source which can not be replaced within a human life span.

Renewable resources

Any material or energy source which can be replaced within a human life span.
