Question

Why is variation beneficial to the species but not necessarily for the individual?​

Answer 1

Species occupy well-defined spaces in the ecosystem, called niches, by increasing their population through reproduction. These niches in the ecosystem may change upon time, even drastically, which are not in control of these organisms occupying the space. The changes, such as an increase in temperature, may cause a threat to the survival of the species in that niche. If the species have variations within the population, some of the variants might be able to cope with the change, thus having a survival advantage. Thus, these variants will survive, leaving behind the individuals in the population with no desirable variation. Thus, these variants help in the survival of species. But, not all variations are beneficial for individual organisms. 

Answer 2

Explanation:

QUESTION:

Why is variation beneficial to the species but not necessarily for the individual?

SOLUTION:

Variations are important for species survival because variation causes the organism to overcome extreme situations. Organism species occupy well-defined positions in the ecosystem, utilizing their reproductive capacity.

Variation beneficial to the species

Even so, for factors beyond the control of the species, such locations will alter and can even destroy the entire species. If any differences in all of these species were to be found in a few individuals, they would have a chance of surviving.

• Variations can be beneficial or harmful according to the ecological niche of the organism.
• A variation suitable for the particular niche is selected by nature in evolution. Thus, variations are necessary for the survival of the species.
• Variation is important for the evolution of the species.
• Variations are beneficial to the species than individuals because sometimes, survival will be difficult for a species under certain environmental conditions. For example, if the water temperature is increased suddenly, the microorganisms living in the water will die soon, and some percentage will survive due to the heat withstanding capacity. Thus, if variations are not there, all the microorganism would have been destroyed.
