What process often begins by a portion of a population becoming physically or geographically separated?
Zane Pint
This is known as evolution. Evolution is the gradual change in the heritable characteristics of biological populations over successive generations due to factors such as natural selection, genetic drift, and mutations. It occurs in response to changes in the environment and can result in the adaptation of organisms to better survive and reproduce in their environment.

All of the populations in an ecosystem?
All the populations in an ecosystem refer to the various species of organisms living and interacting within a specific environment. These populations may include plants, animals, fungi, and microorganisms that are interdependent and contribute to the overall functioning of the ecosystem. Changes in one population can have ripple effects on other populations within the ecosystem.
What is the process by which populations accumulate inherited changes over time?
The process by which populations accumulate inherited changes over time is called evolution. Evolution occurs through mechanisms such as natural selection, genetic drift, mutation, and gene flow, leading to the gradual change and diversification of species. These inherited changes can result in adaptations that increase the fitness of individuals within a population.
What is meant by the statement Populations evolve individuals don't?
This statement refers to the fact that evolution occurs at the level of populations over generations, with changes in allele frequencies leading to evolution. It emphasizes that individual organisms do not evolve within their lifetimes, as they do not change genetically, but rather it is the population as a whole that evolves.
Why was game scarce in the region of the Mackenzie and Yukon river basins?
Game was scarce in the region of the Mackenzie and Yukon river basins due to overhunting by European fur traders, as well as changes in the environment such as deforestation and habitat destruction. This led to a decline in the animal populations that Indigenous peoples relied on for food and resources.
What is ecology How do population dynamics affect ecology?
Ecology is the study of interactions between organisms and their environment. Population dynamics, the study of changes in population size and composition, have a direct impact on ecology as they influence factors such as competition for resources, predator-prey relationships, and species diversity. Changes in population size can lead to shifts in ecosystem structure and function, affecting the overall balance of the ecosystem.
What is a indicator organisms?
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.
What is organic indicator?
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.
How changes in the environment affect a community of organisms?
how changes in the environment affect a community of organisms
How is variation beneficial to a population of organisms?
If that variation is selected on the basis of survivability and reproductive success then the populations gene pool allele frequency changes and the population becomes better adapted to the immediate environment, or adapted to a new and changing environment.
When organisms adapt to changes in the environment it its called?
evolution
What is the modern definition of evolution based on population genetics?
The modern definition of evolution works at the level of genes, phenotypes and populations whereas Darwinism was mainly concerned with organisms, speciation and individuals. According to the modern definition of evolution, the populations evolve by changes in gene frequency brought about by random genetic drift, gene flow and natural selection. This change is gradual.
How may the snowy owl change the environment?
the snowy owl changes the environment by keeping control of their populations of their prey
What do you call the gradual changes in the genetic make up of a population as a result of emigration and immigration of organisms?
Gene flow.
What is an outer environment?
organisms respond to the changes of weather and seasons.
What allows more and more organisms to live in an ecosystem?
changes in climate, rate of erosion, and populations
What is a gradual change in the kinds of organisms living in an ecosystem?
Succession refers to the normal, gradual changes that occur in the types of species that live in an area.
Whats the relationship between balance and change among living things?
So if there is a same amount of populations of different types of organisms, and they are consumers and decomposers, it balances the populations of organisms because they eat other plants and animals. Wheras if you take a population of organisms out that changes organisms
