Food Web vs. Food Chain

Food Web

Food Chain

Biotic factors

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






Abiotic factors

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







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.


Endangered species

Threatened species

Indicator species

Ecological succession

Primary succession

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

Secondary succession


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



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

Non-point source


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


food waste



tree and brush debris

Inorganic pollutants


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

Nonrenewable resource


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.



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