Density-dependent Limiting Factors

Things that limit a population of organism and are dependent on the number of organism.

Density- independent Limiting factors

Things that limit a population organism and are

not dependent on the number of organism.

Biotic Factors

The parts of a specific environment that are

LIVING.

Abiotic Factors

The parts of a specific environment that are not

NOT LIVING.

Predator/ Prey

Predators are consumer  that eat other animals
(called) Prey.

Parasitism

A density dependent limiting factor where one organisms lives on or in

another organism.

Carrying Capacity

The maximum amount of organisms an enviornment can hold, calculated by using the average maximum.

Linear Growth

Growth where the population increases by the same amount every time period.( 0,2,4,6,8,10,12)

Exponential Growth

Growth where the population increases more and more every time period.( 0,2,4,8,16,32,64, 128)

Biomass

The mass (weight) of living organism.

Nitrogen-Fixing

When N2 (nitrogen gas) is changed into NH4 (ammonia)

Nitrification

When ammonia (NH4)  is changed into Nitrates (NO3) and Nitritres (N02)

Denitrification

When extra Nitrates (NO3) and Nitrites (NO2) are changed back into N2 (nitrogen gases.)

Gas Exchange

When gases like O2 9 (oxygen gas) and CO2 (carbon dioxide) move between producers, consumers, and their environment.

Nitrates,

Nitrites,

Ammonia

These substances with Nitrogen that we can eat and use.
