Trophic Levels

Producers

Lowest on the trophic pyramid. All energy is from them.

Primary Consumers

Low on the pyramid. They arent very dominant and they dont eat much.

Secondary Consumers

In the middle they are usually carnivores and have only few predators.

Tertiary Consumers

They are the main consumers in the pyramid. They eat a lot and are top on a food chain.

Decomposers

These are an on the side group they dont do much but decompose. Ex.(a worm)

Biomes

Desert

Forest

Tundra

Grassland/Savannah

wetlands

Desiduous Forest

Rain Forest

Temperate Desiduous Forest

Coniferous forest

Freshwater

Marine

Abiotic Factors

Something that is non-living and never has been living.

Biotic Factors

Something that is living was once living or is part of something living or part of something that was living at one time.

Organism

A living object.

Live in a community, and the number of them is known as their population. We are organisms as well as all other living things around us.

Ecosystem

A system formed by the interaction of a community of organisms with their environment.

Food Chain

A chain of organisms related by their eating habits. Producers are lowest on the chain and tertiary consumers are on the top of the chain.

Food Web

A series of organisms linked by predator and prey and consumer/resource interactions.

Hot Spots

Hot spots are regions with the greatest concentrations of species. They cover 2% of the earths land mass.

Biodiversity

diversity among plant and animal species, genetics, and ecosystems. (the variety).

Genetic Biodiversity

Species Biodiversity

Ecosystem Biodiversity

Endangered Species

a species at risk of extinction because of human activity

Threatened Species

A species likely to become endangered because of humans overexploiting their population.

Ecological Succession

Ecological sucession is the way in which a ecosystem matures. It could be primary sucessino or secondary sucession. Primary starts from scratch, and secondary is rebuilding.

Population growth

It is the births minus the death in a population.

Population Growth rate is the rate at which a population is growing over a period of time.

Pioneer Species

These are the species that start off an ecosystem, when they are rebuilding or just starting. They are very delicate.As are indicator species.

Climax Community

This is when a community reaches full/ is at it's climax. For example when an empty lot turns into a full forest.

Limiting Factors

Limiting factors are factors that keep a population from reaching it's carrying capacity(when a population is at its kept height).

Carrying capacity

The biggest number of organisms that an ecosystem can support. When an ecosystem is full.

Exponential Growth

development at an increasingly rapid rate in proportion to the growing total number or size.

J-curve

A graph when you have a upward increase that is continuing.

S-curve

A graph that has an upward increase and then lavels off at a point. Many populations level off when they reach carrying capacity.

Water Pollution

Water pollution is everywhere throughout the U.S. from trash, to chemicals and toxins. Many of our waterways are polluted.

Aquifier

An aquifier is something used to clean water that is not pure.

Desalination

Desalination means to take the salt out of something such as saltwater.

Water Purification

Means to purify unpure water.

Watershed

A watershed is a basin where all the used water from an area goes. for example a lake or a river.

Impermiable

A surface where water cannot be soaked into.

Erosion

Erosion is when water eats the land away when it does not have proper nutrients.

Runoff

Runoff is water that comes off of impermiable surfaces, usually roads where the water drains into sewers.

Wetlands

land that has a wet and spongy soil, as a marsh, swamp, or bog. Absorbs a lot of water.

Urbanization

When an area becomes urban. Lots of construction is involved.

Point source and non point source.

Point source comes from a specific location and is easy to pinpoint. non point source is from an unknown source and is hard to pinpoint.

Organic and inorganic pollution

Disposal of organic or inorganic wastes as pollution. ex. dog waste and toxins.

natural, renewable and non renewable resources

all materials humans use.
