Prime objective of this lecture is to present on how do Changes in the Environment Affect Organisms. The living and non-living environment affects the survival of an organism. The non-living environment has a major influence on the lives of all other living and non-living things that form an ecosystem. Living things are adapted to seasonal changes in their habitat. Example; Wilderbeast migrate; they travel hundreds of miles every winter looking for grass to eat. Grass will only grow where it rains. Some insects spend winter in protective cases called pupua.
