Terms to remember
Adaptations are traits that make an animal suited to its environment.
Two Types:
Structural Adaptations are inherited physical features of and organism.
(Ex. White fur on a polar bear
Behavioral Adaptations are things organisms do to survive. (Ex. Migration & hibernation)
Biodiversity-The number of different species of plants and animals in an area
Changes in environmental conditions can affect the survival of individual organisms and
entire species.
Long-term environmental changes, like climate change, can permanently alter an
ecosystem, but over time the change may cause some genetic variations to become more
favorable or less favorable in the new environment. If adaptations to the new
environment are not present or do not develop, populations can become extinct.
Short-term environmental changes, like "floods, don’t give populations time to
adapt to change and force them to move or become extinct. Human activity affects
natural systems through agriculture, resource consumption, and pollution from waste
disposal and energy production.
