As you travel higher, the air begins to thin out which makes it harder for you to breathe. There is less oxygen as you travel higher.

Because the air gets thinner. The air at higher altitudes is more uncontaminated oxygen, cleaner air, whereas at low altitudes, air is more contaminated by smog and pollution from factories, power plants, etc.

Explain how temperature and amount of precipitation can affect the type of plants and animals found in the grassland biome?

MArishka [77]

Temperature grasslands have hot summers and cold winters. Summer temperatures can be well over 100 degrees Fahrenheit, while winter temperatures can be as low as -40 degrees Fahrenheit. They typically have between 10 and 35 inches of precipitation a year, much of it occurring in the late spring and early summer. As climate conditions shift geographically so will the distributions of many plants and animals. The relatively flat terrain of grasslands increases vulnerability to climate change impacts, because habitats and species must migrate long distances to compensate for temperature shift.
