When there is limited food.

What is the third step in natural selection?
There are really no steps in natural selection - just conditions required for it to occur.
Why would natural selection not occur in this poplutation?
What population? Perhaps you mean if there were no variation for natural selection to select from.
How is genetic diversity important to the concept of natural selection?
Without genetic diversity, natural selection cannot occur
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
What are the pressures of natural selection?
Everything from available food to climate will cause the changes we see in natural selection. Random mutations occur constantly and when those mutations are beneficial for life, the genetic code is more likely to be passed on to future generations.

what causes natural selection to occur?
the presence of predators
Why would natural selection not occur in this population?
Natural selection may not occur in a population if there is no variation in traits among individuals, if all traits are selectively neutral, or if the environment is stable and consistently favors all individuals equally. Additionally, if all individuals are equally successful in reproducing and passing on their genes, natural selection may not be operating in that population.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
What term is defined as natural change that occur in communities over time?
Natural selection
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
What are the 4 mechanisms by which evolution can occur?
genetic drift, mutation, natural selection, and migration
Which tends to occur more quickly natural selection or artificial selection?
Artificial selection tends to occur more quickly than natural selection because it involves intentional breeding by humans to promote desired traits in organisms. This focused approach can lead to rapid changes in specific characteristics over a few generations. In contrast, natural selection operates through environmental pressures and can take much longer for significant changes to occur, as it relies on random genetic variations and survival advantages over time.
What requires natural selection to occur in a population?
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.
