Introduction of snakes to a new habitat with varied rodent species will likely increase genetic variation in the snake population. The forces of natural selection, genetic drift, and possible mutation will drive this genetic diversity.
The introduction of the snake species to a new habitat with many types of rodents, which constitute their prey, will have an impact on the genetic variation of the snake population. This impact will largely be dictated by the forces of natural selection, genetic drift, and potentially mutation.
For instance, certain traits may favor the survival and reproduction of some snakes over others, depending on the exact nature of the predominant rodent species in the new habitat. This is known as directional selection. If the rodent types in the new environment favor the survival of snakes with certain traits, over time, these traits will become more common among the snake population.
Additionally, genetic drift, which refers to random fluctuations in allele frequencies, may also come into play, especially if the initial snake population in this new environment was relatively small. Over time, these factors, along with potential mutations, can contribute to increased genetic variation within the snake population.

A.Natural selection can influence both predator and prey populations.
B.Nature selects for traits that allow for increased rates of reproduction and survival over traits that don't.
C.Natural selection determines which generations will be influenced by natural selection.
D.One population is not affected by the changes in another population.
Answer:
B
Explanation:
Energy always flows from the sun, to the producer, to the primary consumer, to the secondary consumer, to the tertiary consumer, and so on. Algae has to come after the sun, because it's a producer.
