What are three factors that might kill off less well-adapted individuals struggling to survive in a population?
Competition for resources: Individuals that are less well-adapted may struggle to compete with others in a population for food, shelter, or mates, leading to their decreased survival chances. Predation: Less well-adapted individuals may be more vulnerable to predation by predators, as they may lack defenses or skills to evade or fend off predators. Environmental changes: Changes in the environment, such as temperature fluctuations, natural disasters, or habitat destruction, can pose challenges for less well-adapted individuals to survive and reproduce.
What are three factors that might kill off less well adapted individuals struggling to survive in a population?
Being able to catch prey, Avoid Being eaten, Adapting to their environment.
An organism will survive if it is adapted to its environment. What is the name for this process?
Natural selection
What is the process whereby only the fittest organisms survive and are able to reproduce?
natural selection
Which theory explains that organisms change because of adaptations that help them?
The theory that explains how organisms change due to adaptations that help them survive and reproduce is known as the theory of evolution by natural selection, proposed by Charles Darwin. This theory suggests that individuals with advantageous traits are more likely to survive and pass on their genes to the next generation, leading to gradual changes in the population over time.
How does natural selection and adaptations interrelate?
There is natural selection on individuals, which means the better adapted individuals are more likely to survive and reproduce. Because they pass this strength (as far as it's genetic) on to the next generation, these are also better adapted. So species adapt because the weak individuals get fewer ofsprings.
What do better adapted individuals do?
Survive and reproduce.
Is individuals with variations that make them better adapted to their environment will not survive?
no organisms adapt to the environment to help them survive
How does natural selection require that individuals in a population are adapted to their environment?
Natural selection requires that individuals in a population are adapted to their environment because those with traits that are better suited to survive and reproduce in that environment are more likely to pass on their genes to the next generation. Over time, this process leads to the accumulation of advantageous traits in the population, increasing its overall fitness and ability to thrive in its specific surroundings.
Why do insecticides only work well for a few years?
Insecticides only work well for a few years because the insects undergo natural selection. The insects that are better adapted to survive the insecticide will reproduce and pass down their genes to the next generation and the adapted generation of insects will be unaffected by the insecticides.
Does evolution occur just because an individual organism survives longer in an environment?
No. Evolution occurs because each generation of individuals in a population has slightly different genetics than the one that preceded it and the one that will follow it. There are many different mechanisms that bring these genetic changes about.
What is the process by which individuals are better adapted to their environment will survive?
Natural selection a theory by Charles Darwin
The process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do?
The process by which individuals that have favorable variations and are better adapted to their environment survive and reproduce more successfully than less well adapted individuals is called natural selection. This is part of Darwin's theory.
What is fittest survive?
"Survival of the fittest" is a concept from evolutionary theory that suggests organisms best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to future generations. It reflects the idea that individuals with advantageous traits will be more successful in passing on their genes to the next generation.
What is the process which individuals that are better adapted to their environment are more likely to survive and reproduce is called?
natural selection
What happens to unnecessary traits during the process of natural selection?
During the process of natural selection, unnecessary traits are gradually eliminated from a population because individuals with those traits are less likely to survive and reproduce. Over time, the population becomes more adapted to its environment as only individuals with beneficial traits are more likely to pass on their genes to the next generation.
Natural selection is based on Darwin and observation that individuals most likely to survive and reproduce are those .?
Are those individuals best adapted to their immediate environment.
