AP BIOLOGY

Detailed explanation-1: -Change in an organism’s environment forces the organism to adapt to fit the new environment, eventually causing it to evolve into a new species.

Detailed explanation-2: -Food shortage as the lands become barren and the oceans become fishless. Loss of biodiversity as whole species of living things disappear due to deforestation. Pollution will eventually become unmanageable and affect our health. Rising temperatures may be too much for all living things on the planet.

Detailed explanation-3: -If one organism forms food for different organisms in the ecosystem, there will be a lot of competition among those organisms for food. Competition may lead to extinction of any group of organisms who are dependent for food on one particular organism.

Detailed explanation-4: -Some disruptions can be devastating for an individual species and may even cause an entire species to permanently disappear in a process called extinction. As species become extinct, the variety of species in the biosphere decreases, which decreases biodiversity, or the variety of life.
