This could be anything, from earthquakes to migration to floods to disease, and so on, and so forth. In nature, population sizes naturally fluctuate even without such events, due to changes in the availability of resources, predation, and so on.

What must occur for a population to grow?
The rate of reproduction must be higher than the mortality rate.
What condition is necessary for genetic drift to have a significant effect on a population A natural disaster must occur. The population needs to be small. Gene flow must occur. A portion of the p?
The population needs to be small is the necessary condition for genetic drift to have a significant effect on populations.
What must occur for a population to diverge?
Reproductive isolation: a decline in interbreeding frequency between two segments of the ancestral population.
What is the one of the conditions for Hardy-Weinberg equilibrium?
All organisms must reproduce.
Which is one of the conditions for Hardy-Weinberg equilibrium?
1.The population must be infinitely large 2. There must be no mutations 3. Breeding amongst the population must be random 4. There must be no Immigration or Immigration There are more conditions so let me know if you need the rest Mutation cannot occur
What must happen for specification to occur?
A population must be isolated in some way
4 Under what conditions might a death phase occur?
when the population decrease rapidly , it is said to crash.
What must occur for a gene pool within a population to change?
A genetic mutation within the population.
What must occur for a population to grow?
The rate of reproduction must be higher than the mortality rate.

The population needs to be small is the necessary condition for genetic drift to have a significant effect on populations.
What must be true for equilibrium to occur?
No disruptive circumstances must be present in random mating in a population for Hardy-Weinberg equilibrium to occur. Mating must happen randomly. No allele can give an advantage
What must occur for a population to diverge?
Reproductive isolation: a decline in interbreeding frequency between two segments of the ancestral population.
What will happen if the plankton population decrease?
The population of zoo plankton would decrease.
How would a decrease in natality change the population?
A decrease in the birth rate will cause a decrease in population over time.
Possible reasons why a rabbit population may decrease?
Death and migration are factors that can decrease hare population.
What must occur for the gene pool within population to change?
natural selection or genetic drift
What is the one of the conditions for Hardy-Weinberg equilibrium?
All organisms must reproduce.
