What is a process through which new species can arise?
Natural selection that leads to a great enough change in allele frequency over time in a population of organisms, evolution, and helped by environmental changes to create sub-populations of these organisms that can no longer breed among themselves and then are accounted new species.
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.
Compare coevolution and symbiosis?
A coevolution is the reciprocal changes in two or more populations and a symbiosis is when two different organisms live in close associations with each other! HOPE THAT ANSWERED EVERYONE'S QUESTION!!!! :)
Changes in genes occur when organisms produce?
changes occure when organisms produce are called fertile offspring.
What is the name for the study of the changes in the sizes of populations?
Population dynamicstion…
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.
If Organisms are able to adapt recurring environmental what changes would be likely to?
reproduce
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.
What allows more and more organisms to live in an ecosystem?
changes in climate, rate of erosion, and populations
What is a process through which new species can arise?
Natural selection that leads to a great enough change in allele frequency over time in a population of organisms, evolution, and helped by environmental changes to create sub-populations of these organisms that can no longer breed among themselves and then are accounted new species.
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
Can you give me ecology in a sentence?
ecology may be defined as influence of environmental changes on the living organisms
What changes did humans make that affected local environments?
They change the food we eat , and the populations unprecedented rate grew.
Gradual change in populations of organisms that occurs when the environment changes?
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.
Natural selection causes changes in populations of organisms not individual organisms because?
differential reproductive success caused by genetic variation is necessary for the process of natural selection.
What environmental factor has been most recently affected by changes in carbon dioxide in the atmosphere?
The temperature of the atmosphere (it has risen).
What is the particular development behavior or physiological change in a population of organisms in response to changes in the populations?
Phenotypic plasticity and adaptation are two ways a population changes in response to changes outside the population. This is how evolution works.
