Environmental Science Max Claycomb

Biodiversity

3 types

genetic, make up

species, different types

ecosystem, difference in ecosystems

Hot spots

an area where there is lots of biodiversity. Only 17 left on earth and all are pretty close to the equator.

Biotic and Abiotic

Biotic

is a living thing, was a livin thing, or was a part of a living thing, animals, humans, plants

Abiotic

never living, metals, water, air

Food Web and Food Chain

Food Chain

arrows showing transfer of E

Food Web

shows the connections between food chains better an descirbes a ecosystem.

Trophic Levels

Producer, Gets 100% of the energy

Primary Consumer, Gets 10% of the energy

Secondary Consumer, Gets 1% of the energy

Tertiary Consumer, Gets .1% of the energy

Decomposer

Levels of Organization

Organism

a living thing

Population

a group of the same species living together

Community

different types of organisms that live together and interact

Ecosystem

habitat where different organisms survve and interact

Biomes

geographic area that contains many ecosystems determined by climate, EXAMPLES least to greatest(biodiverse wise), Tundra, Desert, Freshwater, Grassland, Coniferous Forest, Temperate Deciduous, Marine, Rainforest

Species

Indicator species

Species that canonly live in a certain area

Endangered species

A species in danger of extinction throughtout most or all of the area it inhabits

Threatened species

A species likely to become endangered in the near future

Pioneer species

A species that appears early in succession and grows fast, requires few resources, and thrives with little competition.

Climax Community

Large, grow very slowly, and reproduce quickly an dominate in community. Climax Communitites neverchange unless there is a disturbance.

Ecological Succession

the process in which the community of an ecosystem changes over time

Primary Succession

occurs where life never existed before like a new island. seeds come to island and slowly life begins to grow.

Secondary Succession

process that begins in an ecosystem when something occured that destroyed the ntural community. At an abondoned farm or Yellowstone due to fire.

Population Stuff

Limiting factors

Conditions of the environment that limit the growth of a population.(Biotic and Abiotic factors)

Carrying Capacity

Is the number of individuals of a species that an ecosystem can support

Population Growth

The total amount of the species that inhabit the area

Population Growth Rate

The rate at which the species is growing, can be positive and negative

Graph Stuff

J-Curve

Exponetial Growth is at the sudden increase

S-Curve

Is like the J-Curve but then begins tolevel off over time and has NO POINT at which it stops increaing

Water Pollution

the contamination of water bodies

water purification

the process of getting rid of unwanted contaminents from water.

Desalination, any processses that remove minerals from water.

Types of pollution

Point source, pollution that comes from one specific area and can be identified.

Non-point source, pollution that comes from many areas and cannot be identified

Impermeable, not allowing the passage of fluids thrugh a material, Impermeable surfaces lead to RUNOFF, Runoff is water that can't be absorbed by plants and ends up going into some sort of drainage like storm sewers.

Organic pollutant, contaminents in an environment that can be biodegraded by microorganisms

in-organic pollutant, contaminents in an environment that can not be biodegraded by microorganisms

Water Bodies

Aquifer, an undergrounf layer of water bearing permeable rock, from which groundwater can be extracted from.

Watershed, an area of land where all of the water that it drains off of goes to the same place

Wetlands, an area of land whose soil is saturated with moisture either most of the year or all of it, and a habitat for certain types of animals., when wetlands are destroyed, it leads to more erosion, erosion is the process that moves solids in the natural environment and deposits it somewhere else.

Extra Stuff

urbanization

the physical growth of urban areas as a result of global change

Resources

natural resouces

materials that can be found on earth

renewable resources

a material that can be used and replaced before the end of the human life span

non renewabe resources

a material that cannot be replaced before the end of a human life span
