negative effects of forest fires
- habitats being destroyed
-plants and animals being killed
positive effects of forest fires
- clears space for new plant growth
- ashes provide nutrients for soil
- pinecones open to let seeds out
ways water can affect the environment
erosion, flooding, and drought
What organism thrives in floods?
mold
How can people change the environment?
using resources
How do animals and plants change the environment?
naturally through living and eating in the area
Can all organisms survive in areas that are flooded or where there are droughts?
No, they either die or move to new locations
What happens if nonliving things cause the ecosystem to change?
the living things will be affected
