how do people impact an ecosystem
-
when people build structures like dams, or develop land on the banks of rivers, it can cause flooding, which can affect the species living there.
-
People can also accidentally start fires, which can destroy entire ecosystems!
-
People can also change ecosystems by cutting down trees and destroying habitats so that they can make room for buildings, houses, farms and roads.
Desert biome -
-
The desert biome is an ecosystem that forms due to the low level of rainfall it receives each year.
-
Deserts cover about 20% of the Earth. There are four major types of desert in this biome - hot and dry, semiarid, coastal, and cold. They are all able to inhabit plant and animal life that are able to survive there
-
Although the daytime temperatures of the desert biome are very hot, they can get very cold at night.
-
The Sahara Desert is the largest desert in the desert biome. It covers over 300 million square miles.
-
The vegetation does not grow very tall so the desert biome can only accommodate small animals, rodents, and reptiles. These animals can escape the harsh Sun by hiding under small scrubs or hiding in burrows.
