Question

Check all statements below that are true.

All organisms must compete for survival.

When organisms struggle to survive, they usually mutate to increase chances of reproduction.

Some organisms have phenotypes that make them better competitors than others in their environment.

Animals undergo natural selection, but plants and other organisms generally do not.

Natural selection continues to occur even today.

Phenotypes found in the most successful members of a species become the most prevalent after several generations.

A decrease in food availability will increase the variation in a population.

Answer 1

1,3,5 and also 6 because the organisms can't just mutate on the spot, it takes time and lots of offsprings

Answer 2

All organisms must compete for survival.

Natural selection continues to occur even today.

When organisms struggle to survive, they usually mutate to increase chances of

reproduction

A decrease in food availability will increase the variation in a population

Step-by-step explanation:

According to Charles Darwin in his theory of natural selection, organisms must compete for scarce resources. Only the fittest can survive. The fittest are organisms that have undergone the required genetic changes that increases their chances of survival. They pass on these genetic changes to the next generation or offspring.

When availability of food decreases, organisms begin to change genetically as they struggle for scarce resources thereby leading to variation in a population.
