Food Web vs. Food Chain

Food Web

Factors involved in food chains and webs, Trophic Level, Producer, Dandelion, Primary consumer, Rabbit, Secondary consumer, Fox, Tertiary consumer, Bear, Decomposer, Fungi

Food Chain

Biotic factors

Biotic factors: these are living things. They also could have been living or are pieces of a living thing.

whale

hair

snail

apple

paper

Abiotic factors

Abiotic Factors: these are non-living. They were never living and will never be living.

sand

water

temperature

air

sunlight

Biodiversity

Def. variety of organisms found within a specified geographic region.  

Genetic biodiversity

Def. Is the difference in genes in an ecosystem

Species biodiversity

Def The difference among the plants and animals.

Ecosystem biodiversity

Def. The difference between ecosystem.

Hot Spots

Def . A small region where there is a great biodiversity.

species

Endangered species

This is a species that is on the verge of going extient.

Threatened species

This species is starting to become threatened.

Indicator species

This species is sensitive to pollution or other harmful things in the enviornment. They help show how an ecosystem is doing.

Ecological succession

Primary succession

Pioneer species form at the beginning of succession while climax community is at the end.

Secondary succession

Population

Population growth

This is how the population is growing The population of a country is either rising, sinking or staying the same.

Population growth rate

It is how fast a population is growing. Or how fast they did grow.

Limiting factor

Is a factor that reduces the population in an ecosystem. This can be good if an ecosystem is reaching carrying capcity.

Carrying capacity

It is when an ecosystem reaches the point where it can't carry any more organisms.

Exponential growth

J-curve

S-curve

Water Pollution

Water pollution is very dangerous to aquatic life as well as humans. It can cause illness, kill animals or contaminate the water.

Point source

This is pollution that comes from a direct location. This is easy to pin point and the pollution is usually sent directly intot he river, stream, lake or ocean.

Non-point source

This pollution is hard to stop because it comes for a variety of different locations.

Watershed

This is an area where all the water will drain into one location. The watershed that we are in is the Delaware Basin.

Organic Pollutants

cleaners

food waste

detergents

petroleum

tree and brush debris

Inorganic pollutants

fertilizers

discharges from a power plant

sediment from runoff

acid from metal

Impermeable surface

This is a surface that doesn't allow water to go through it, like sidewalk, roof or blacktop. These surfaces are not good because water easily travels down them, which collects trash and other pollutants.

Natural resources

These are materials or things that come directly from nature. Like trees, oil, water and air.

Renewable resource

This is any material or energy source that will be replaced within a human life time.

Nonrenewable resource

This is any material or energy that will not be replaced during a human life time.

Erosion

Erosion is the process were solids like sediment, rock and are moved and placed in a different location. One major cause is runoff. This is were water moves down a surface into a water source. This moving water will often pick up sediments rocks and trash, which is also a cause of water pollution.

Water purification

Water purification is a process that is used to make water that is not drinkable, drinkable. One method is desalination. This is were we remove salt from ocean water. Ninety eight percent of all the water on earth is in ocean, which are hard to change into drinkable water. Aquifers or under ground water tunnels have the easiest and most drinkable water on earth.

Wetlands

Urbanization

This were there is an increased number of people populating urban areas like cities.
