Answer:
The environment usually refers to all the biotic and the abiotic components that are surrounding us. This environment undergoes changes depending upon various factors which can be natural and/or due to the anthropogenic activities.
When there occur rapid environmental changes, then it directly affects the lives of species, in different ways, such as-
- Those species that are comparatively weaker in adapting according to the environmental changes that occur, will not be able to cope up with the new environment. They may become extinct.
- Some variety of species will be able to adapt to the new environment because of their easily adapting capabilities.
- The traits that will be developed within the species in the new environment will be more successful in terms of reproduction.
- The previously existed traits may have a harmful impact in the newly formed environment.
