Predation can affect biodiversity in two ways. In a positive way, predation allows for the biodiversity in an area to flourish, meaning that certain animals/plants being kept 'in check' will allow for other plants and animals to flourish. In a negative way, however, predation can decimate certain aspects of an area - such as a certain plant or animal, and this can affect the entirety of the food web for the area.

How did natural selection affect peppered moths?
During the industrial revolution, peppered moths with dark coloration had better camouflage on soot-covered trees, allowing them to avoid predation and survive to reproduce. Over time, the frequency of dark-colored moths increased due to their enhanced survival, demonstrating natural selection operating on the population.
How do natural selection and sexual selection differ in their roles in shaping the evolution of species?
Natural selection and sexual selection are both mechanisms of evolution, but they differ in how they shape species. Natural selection acts on traits that affect an organism's survival and ability to reproduce in its environment, leading to adaptations that increase survival and reproduction. Sexual selection, on the other hand, acts on traits that affect an organism's ability to attract mates and reproduce, leading to the development of traits that enhance mating success. In summary, natural selection primarily influences survival and reproductive success in the environment, while sexual selection primarily influences mating success and reproductive opportunities.
What is another word for Darwin's theory of natural selection?
Evolution by natural selection.
How can genetic drift and gene flow affect natural selection?
Genetic drift can reduce genetic variation within a population, making it harder for natural selection to act upon beneficial traits. Gene flow, on the other hand, can introduce new genetic variation into a population, potentially increasing the pool of traits for natural selection to act upon. Overall, both genetic drift and gene flow can influence the effectiveness of natural selection by altering the genetic composition of populations.
Is natural selection the only force that drives biological evolution?
No. Natural selection requires reproductive variation to work on. Besides reproductive variation and natural selection, there are various forces, biochemical as well as population dynamical, that affect the allelic composition of a population.
Is random selection of prey essential in any model of natural selection?
No, many forms of natural selection have no connection to predation.
How predation plays a beneficial role in natural selection?
Poorly adapted organisms are more vulnerable to predation. This is one of the means by which they fail to survive as well as better adapted organisms.
How does selection affect natural selection?
Organisms are affected by Natural Selection because Inherited characteristics affected the likelihood of an organism's survival and reproduction.
How did natural selection affect peppered moths?
During the industrial revolution, peppered moths with dark coloration had better camouflage on soot-covered trees, allowing them to avoid predation and survive to reproduce. Over time, the frequency of dark-colored moths increased due to their enhanced survival, demonstrating natural selection operating on the population.
Which does natural Which does natural selection affect?
natural selection is basiclly only the strong survive which means it effects the weak by killing them but bernifits the strong
How does natural selection affect survival?
Natural selection is the process which determines the shark's evolution. It is humankind that is threatening the sharks' survival.
Which does natural selection affect populations or individuals?
Populations evolve, but individuals are selected. Natural selection affects individual organisms.
What other theories are there except for natural selection?
Evolution by natural selection is currently the only viable theory explaining the diversity of life. However, the mechanism of natural selection is not the only mechanism to affect evolution. There are phenomena such as genetic drift, biased gene conversion, intragenomic conflict, and so on, that aren't exactly the same as natural selection (although they are all intertwined and all affect one another), but do affect the direction of evolution.
How does Evolutionary Trends affect Natural Selection?
Adaptation for stronger shells.
What are the three ways natural selection can affect the distribution of phenotype?
Blah
What happens to unnecessary traits during the process of natural selection?
How does natural selection affect undesirable traits?
Why does natural selection not directly affect genes?
Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this interaction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.
