What is population
100
organism that eats away at a dead organic matter
What is decomposers
100
largest number of individuals of a particular species that can survive over long periods of time in a given enviroment, this level depends on the effect of the limiting factors

What is biotic
200
interrelate group of different species in a common location
What is community

is the gradual growth of an ecosystem from bare rock.
What is primary succession
200

environmental factor or environmental factors that limit the growth, abundance, or distribution of a population of organisms in an ecosystem.
What is limiting factor
300
hanges that occur as a previously damaged ecosystem recovers
What is secondary succession
300
is a type of forest characterized by trees that seasonally shed their leaves this include forests which produce nuts and winged seeds, Marple, beech and oak.
What is temperate deciduous forest
400
increase the average temperature of the Earth's surface, enough to cause climatic change.
What is global warming
400
organism that does not synthesise its own food and as such depends upon other complex organic substances for nutrition
What is consumers

What is taiga
400
growththe growth of bacterial cells increases by a multiplicative factor per unit of time.
What is exponential growth
400
A type of natural resource that cannot be replenished or takes time for nature to produce or replenish in order to sustain the rate of consumption.
What is nonrenewable resources

What is savanna
500
a plant community of drought-adapted shrubs, usually found in rocky and rapidly drained shallow soils. Dense vegetation consisting of stunted trees or bushes.
What is chapparal
500
number of individuals in a population relative to space.
What is population density
500
is the kind of population growth where the growth rate constantly decreases with the increasing number of individuals.
