For example if a whole bunch of grasshoppers come hopping in your front yard it can be helpful because other animals can eat them. But if the grasshoppers eat other insects that will be harmful.
how changes in the environment affect a community of 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.

organisms respond to the changes of weather and seasons.
They Began to Adapt to the changes over a certain period of time
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.

evolution
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.
