Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences. … Variation within species affects how organisms interact with each other and their surrounding environment.
What role does variation play in biodiversity?
Variation within species affects how organisms interact with each other and their surrounding environment. For example, the size of a fish’s mouth, known as its gape, varies and determines the size of prey it can eat. … “Traditionally, ecologists have focused on the ecological importance of biodiversity among species.
What is variation in biodiversity?
Biological diversity, often shortened to biodiversity, is the variation of life at all levels of biological organization, referring not only to the sum total of life forms across an area, but also to the range of differences between those forms.
Why is variation of a species and diversity of life important?
Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment.
Why is variation between species important?
Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. … Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
What is a variation in a species?
variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).
How does variation within a species contribute to the health of the species of an ecosystem?
How does variation within a species contribute to the health of the species? … The more variation the healthier the species as a whole. If environment changes then there is a chance that a gene will become advantageous and the species may survive.
Why is biodiversity and variation important to ecosystems?
Biodiversity is far most important for the existence of the species. It also facilitates variation among the organisms interacting. Biodiversity facilitates the storage of nutrient, pollution break down etc. … These are the reasons to why biodiversity is important for the ecosystem and the humans.
Biodiversity is a complex term that includes not only the variety of different animals (species diversity) but also the difference between animals of the same species (genetic diversity) and between ecosystems (ecosystem diversity).
What is variation and its importance?
Variations improve the chances of survival of a particular species on the onset of unfavorable conditions. … Variation is the major source of species and environmental evolution wherein the more fit organisms replace the less fit organism from the environment they were earlier sharing.
Why do you think biodiversity is important in the survival of the species?
Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.
What do you think is the role of genetic species and ecosystem diversity in the environment?
The whole area of agricultural productivity and development depend on genetic diversity. The plant as well as animal genetic resources play important role in the economy of a country. Genetic diversity is the whole basis for a sustainable life system in the earth.
What is difference between ecosystem and biodiversity?
Biodiversity is the biological variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level. An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact.
Does variation increase biodiversity?
They found that an increased genetic variation and the rate of generation of new species had little effect on general biodiversity.
Why is variation important for a species Class 10?
Variations are important as they ensure the survival of species over time and with the changing conditions. The niches and the environmental conditions change with time, the variations in the species helps them to adjust, adapt and survive the changes.
How does the new species are produced due to variation?
How do new species arise? New species arise through a process called speciation. In speciation, an ancestral species splits into two or more descendant species that are genetically different from one another and can no longer interbreed. Darwin envisioned speciation as a branching event.
