There are many changes that can occur in an environment, such as natural disasters like droughts and floods, or diseases. These changes can affect living organisms in different ways - some are able to migrate to find a new habitat, others can adjust to survive, but some cannot adapt and end up dying. Common natural disasters that can degrade habitats include droughts, which dry rivers and soil, and floods, which can wash away plants and soil.

some organisms:
1- Move to find a new habitat.
Elephants migrate in search for water & g

8. 2- Adjust to survive.
Some predators hunt other
things.
Some frogs & fish burrow
“make a small hole & stay in
it” themselves when their
environment becomes dry.

9. 3- Cannot adjust or migrate so
they die.

10. Diseases
Examples:
Molds Bacteria Mildew

11. Population
They are a group of living
organisms of the same kind
living together in the same
place.

12. Community
All the population in an
ecosystem make a community.

13. - When there are only a few living members of
an organism left “animal or plant”, it becomes
endangered.
- Examples
- Bengal tiger Saharan cypress
