Question

what is the benefit of variety between organisms within a population?
all individuals can use the same food source
genetic variation allows a species to survive environmental changes
fewer individuals will survive as a result of the variety

Explanation:

Genetic variation means that within a population, there are different genetic make - ups among individuals. When the environment changes (such as a change in climate, availability of food sources, or the introduction of a new predator or pathogen), having genetic variation increases the likelihood that at least some individuals in the population will have traits that are well - suited to the new environment. For example, if a disease affects a plant population, some plants with a particular genetic variation may be resistant to the disease. If all individuals could use the same food source (the first option), it might lead to more competition for that single food source, especially if the food source becomes scarce. The third option “fewer individuals will survive as a result of the variety” is incorrect because genetic variation generally increases the chances of population survival, not decreases it.

Answer:

genetic variation allows a species to survive environmental changes
