9. 7. Why is variation beneficial
species but not necessarily for the individual ?
Answers
Answer:
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.
Example:
A population of heat resistant bacteria in the temperature of the water survives if the temperature of water increases by global warming but most other bacteria would die.
