What natural factors can change a population?
parasites predation weather and clement are four ways natural factors can change a populations size.
Which factors affect a populations growth regardless of the populations size?
density - dependent limited factors
Factors in the environment that limit the size of populations are known as?
predation
Which of these is the study of human populations size and the factors that influence it?
demography
What factors contribute to changes in populations?
parasites predation weather and clement are four ways natural factors can change a populations size.
How can populations change in size?
Populations can change in size due to factors such as birth rates, death rates, immigration, and emigration. If the birth rate is higher than the death rate and there is more immigration than emigration, the population will increase. Conversely, if the death rate is higher than the birth rate and there is more emigration than immigration, the population will decrease.
Predators are abiotic factors that limit the size of prey populations true or false?
False. Predators are biotic factors that influence the size of prey populations by consuming them. Abiotic factors are non-living elements like temperature, water, and sunlight that can also affect population size but are not predators.
Which factors affect a populations growth regardless of the population size?
The basic needs like food, shelter are some of the factors that affect the population's growth regardless of the size.
How do seasonal variations affect population and ecosystem?
Yes. Seasons can change the size of populations
What do scientists think happens is population change over time?
Scientists believe that populations can fluctuate in size over time due to factors such as birth rates, death rates, immigration, and emigration. These changes can be influenced by various factors like available resources, competition, predation, disease, and environmental conditions. Over time, populations may reach a stable size (carrying capacity) or experience boom-and-bust cycles depending on these factors.
What are the 3 reasons why populations change over time?
One reason is because of the economy in the community. Others reasons may include because of the schools and because of culture changes.
Does natural selection require small population size?
No. Natural selection works in all populations. However, new alleles spread more slowly in large populations; the large size has a stabilizing effect. So one should expect large populations to change more slowly than smaller populations.
