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. Much of the time, traits like fish gape are adaptive; they help organisms live in a changing world.
Why is having variation in an ecosystem important?
Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.
What determines the health of an ecosystem?
A commonly cited broad definition states that a healthy ecosystem has three attributes: productivity, resilience, and. “organization” (including biodiversity).
What is the importance of variation between members of a species?
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.
What is an example of variation within a species?
For example, humans have different coloured eyes, and dogs have different length tails. This means that no two members of a species are identical. The differences between the individuals in a species is called variation.
What is an indicator of the health of an ecosystem by the variation of life that exists in it known as?
Biodiversity, n. The variability among living organisms on the earth, including the variability within and between species and within and between ecosystems. … Greater biodiversity in ecosystems, species, and individuals leads to greater stability.
What does indicator species tell us about the health of an ecosystem?
Indicator species (IS) are animals, plants, or microorganism used to monitor changes in our environment. For example, they can tell us about the impact of pollution on an ecosystem, or how well an impaired environment is being managed or restored.
What makes an ecosystem healthy and maintained?
We propose that a healthy ecosystem is one that is sustainable – that is, it has the ability to maintain its structure (organization) and function (vigor) over time in the face of external stress (resilience). … A three-dimensional plot of system vigor, organization, and resilience.
How does variation help a species survive?
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 variation and importance of variation?
Hint: Variations refer to the development of changes in the gene pool of a population of the genotype of a particular organism in due course of time, giving it better adaptability in the changing environment. … Variations enable better adaptation of an organism in the changing environmental condition.
What are variations how do they help organisms?
Answer : Variation can be defined as the differences among individuals within a same species which develops due to the mixing and assortment of genes of the parents that is passed onto the offspring’s. This helps in the individualism of any organism from the other organisms of same species or within a community.
