Lesson Over Short and Long Term Changes 8.11B

Environmental Changes

Short and Long Term Changes

​Changes in the environment affect all organisms that make a specific ecosystem their home. These changes affect both current and subsequent populations.

​Environmental Change: is a change or disturbance of the environment caused by human influences, natural disasters, or ecological processes.

Multiple Choice

environmental change is described as

• breeding of organisms

• a disturbance in the environment

• changes in genetic material

​
Short term Changes: Affect the survival of population immediately, but don't necessarily affect genetics. Organisms do not have time to adapt.




Long Term Changes: Occur over long periods of time. Organisms may adapt to change.

Multiple Choice

Affects organism immediately

• Short term impact
• Long term impact

Multiple Choice

Due to several days of downpours the rivers have overflowed their banks causing localized flooding.

• This is a long term impact.

• This is a short term impact.

Multiple Choice

Causes changes in DNA of the organism causing adaptations.

• Short term impact

• Long term impact

Multiple Choice

The environmental impact of mining includes erosion, loss of biodiversity,contamination of soil and water

• This is a short term impact.
• This is a long term impact.

Multiple Choice

When an environment changes, some organisms are better adapted to deal with the change. What will these organisms do?

• They will survive and reproduce, passing on their genetic traits.

• They will survive but they will not reproduce.

• They will not be able to pass on their genetic traits.

• None of the above

Multiple Choice

Changes to an environment may make it more difficult for an organism to find-

• food.

• shelter.

• water.

• all of the above

Multiple Choice

When changes to an environment happen, animals-

• move.

• perish.

• adapt.

• all of the above

Organisms adapt to the conditions of the ecosystem they live in. Two kinds of adaptations that can occur in response to changes are structural and behavioral

​

Adaptations

These actions that the organism takes to survive.

These adaptations are learned.

Behavioral

These are Physical adaptations.

They are inherited genetically.

Structural
