Immigration, diseases, different movements, reform or otherwise,a harsh winter storm can kill many plants and animals.
Most of the times chemicals from factories are dumped in rivers due to this fishes die and when fish die pelicans or any bird dependant on fishes survives.

Huh? ^^ That Makes NO Sense .

∙ 13y agoWell animals mate or have babys and they grow up and do the same
Wiki User
∙ 13y agowell animals need 2 a male and a female those two can make varying numbers of babies depending on species so that makes 1 to 12 once a gen depending on species

Are wildlife populations static (stay the same) or do they fluctuate (change) as part of an overall balance?
They change over time in response to factors in the environment such as weather and food supplies.
What is a change of a species over time called?
Evolution is a change in species over time.
Do species always change over time?
Species not always change over time such sponges :D
How can populations change in size?
the populations can change in size because there could be more of the offspring.
How did Darwin observe that all species populations have the reproduction potential to increase exponentially over time?
He didnt, someone told him
What is the process by which populations change over time?
Populations change over time due to the process of?
What is a process in which populations gradually change over time?
Evolution i think
How did the plant populations in the community change over time?
by plants moving
What is the definition elevution?
Change over time in populations of organisms. Or, more formally; the change in allele frequency over time in a population of organisms.
What happens to a populations alleles as they change one time?
Evolution is the change in the frequency of alleles of a population of organisms over time.
What do scientist think happens as populations change over time?
new species form.
What is the scientific theory of the states that populations change over time in response to changes in the environment?
it is evolution
The change in the inherited traits of populations of organisms over time is known as?
It is called genetic drift.
Can populations evolve?
Evolution is the change in allele frequency over time in a population of organisms.Short answer, populations are the only thing that evolves. Individuals die. Traits are passed on to progeny that make up the variations in the populations that evolve.
How is a hybrid zone most likely to change over time if hybrid offspring have higher fitness than both parental populations?
If hybrid offspring have higher fitness than both parental populations, the hybrid zone is likely to expand over time as hybrids outcompete the parental populations. This can result in genetic swamping, where the hybrid gene pool replaces that of the parental species. Over time, this can lead to the eventual fusion of the two parental populations into a single hybrid population.
Are wildlife populations static (stay the same) or do they fluctuate (change) as part of an overall balance?
They change over time in response to factors in the environment such as weather and food supplies.
