During periods of rapid environmental change, what may happen to a species that was well-suited to the former environment?
Hunter-Best [27]

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.
