In natural selection why do animals die?
Why do some animals die while others thrive?
Why do phenotypes of a population change?
it is because each animals have a certain stage that it will die ,e.g old age.
it is because each animals have a certain stage that it will live ,e.g old age can cause the animals death
Availability of food and vulnerability to predators. Natural mutations might make changes in phenotypes that help in dealing with the two factors above. Those would then tend to reproduce.
In natural selection, animals die for various reasons, but it all relates to the fundamental idea of adaptation. Natural selection is the process through which certain traits become more or less common in a population over successive generations.
Animals die primarily due to factors like predation, disease, competition for resources, or environmental conditions that they are not well-suited to survive in. These factors create selective pressures that determine which individuals will survive and reproduce.
Regarding why some animals die while others thrive, it comes down to how well-suited an animal is to its environment and the specific challenges it faces. Animals with traits that increase their chances of survival, such as better camouflage, speed, or defensive mechanisms, are more likely to thrive and pass on their genes to future generations. On the other hand, animals with traits that make them less successful in survival and reproduction are more likely to die out.
The phenotypes of a population change because phenotypes are the physical expressions of an organism's genetic makeup. Through natural selection, individuals with advantageous or beneficial phenotypes are more likely to survive and reproduce, passing on their traits to the next generation. Over time, this leads to a change in the phenotypic composition of a population as certain traits become more or less common.
To understand these concepts further, it can be helpful to study specific examples of natural selection in action, such as the peppered moth's color change during the industrial revolution or the beak adaptations of Galapagos finches. Additionally, learning about genetics and how traits are inherited can provide a deeper understanding of how natural selection shapes populations over time.
