What is a indicator organisms?
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.
What is organic indicator?

What is an outer environment?
organisms respond to the changes of weather and seasons.
What are advantages of variation?
Advantage- On the species level, variation allows a population to maintain a healthy diversity, allowing it to cope with changing circumstances.Disadvantage- On the individual level, variation may lead to detrimental changes as well as neutral and beneficial changes.
Increased genetic variation often helps organisms withstand changes in the?
Environment
When is variation most important in evolution?
When the immediate environment changes and stress is put on organisms. Then those who have the variation that will become beneficial in this environment will be reproductively more successful.

How is variation beneficial to a population of organisms?
If that variation is selected on the basis of survivability and reproductive success then the populations gene pool allele frequency changes and the population becomes better adapted to the immediate environment, or adapted to a new and changing environment.
What might be the evoluntionary significance of the swicth from asexual to sexual reproduction when the environment changes?
Environmental changes almost demand variation in organisms so that the best fitted to the changing environment survive and reproduce in a greater number. Asexual reproduction produces clones with little to no genetic variation. Good enough for a static environment, but in a challenging environment with no variation that could be more beneficial than cloning the asexual species could find itself selected against.

Why are mutation and recombination important in the process of natural selection and the evolution of organisms?
When a mutation occurs in the replication process, it changes certain features, like maybe better eyesight, and maybe bigger eyes, or bigger claws, and the meaning of evolution is when something changes into a better form.
What life process by which organisms respond to changes in the environment is?
Regulation
