Carrying capacity of the environment
Life span of the species
Level at which extinction is reached
Level of maximum biodiversity of the species
Resources in the environment are limited.
More organisms migrated into the population than out of the population.
The birthrate gradually became greater than the death rate.
The final population size is greater than the carrying capacity.
The population has reached the carrying capacity of its environment.
Energy is used for interbreeding between members of different species.
A predator recycles the remains of dead organisms.
Competition does not occur between members of different species in the same habitat.
All the insects in the box are the same age.
The insects hibernated from January to April.
The population has carnivorous members.
The population reached carrying capacity by January.
The carrying capacity of the environment
The lack of natural predators
Cycling of energy
Increased numbers of decomposers
Heat energy released by carnivores
Carbon dioxide in the atmosphere
Decomposers in the soil
Autotrophs in the habitat
