How can biotic and abiotic factors affect the size of a population? Give an example of a biotic and an abiotic factor that could affect a population of snakes living in a prairie?
Biotic and abiotic factors affects the size of a population in different ways in such a way that the biotic factors include factors such as presence of plants and animals that threatens the population which could be a predator-prey contest and such would have a direct effect on their population while the abiotic factor also has direct effect on size of population such as presence of extreme temperature in an environment which would make some animals to migrate to a new environment where they seems to thrive better. example that suits both biotic and abiotic factors that could affect the size of a population is predator-prey contest e.g hunting of snakes by humans affect the size of population and increase in temperature which is an abiotic factor allow snakes to migrate to a new environment that suits them
Biotic factors:- are living factors that can affect living organisms in an environment. If a species doesn't have any natural predators it can be regulated by things like disease.
Abiotic factors:- are non-living factors that can affect living organisms in an environment. Population size here can be regulated through natural disasters like floods, tornadoes, etc or things that affect climate like rain and temperature.
Hypotonic solutions are those with less solute (again read as higher water potential). Isotonic solutions have equal (iso-) concentrations of substances. Water potentials are thus equal, although there will still be equal amounts of water movement in and out of the cell, the net flow is zero.
