The vegetation of grasslands is primarily composed of grasses and other herbaceous plants. Dominant grass species include buffalo grass, blue grama, and western wheatgrass. Other common plants include wildflowers, sedges, and rushes.
Wildlife
Grasslands support a diverse array of wildlife. Large herbivores such as bison, pronghorn, and elk graze on the grasses, while smaller mammals like prairie dogs, ground squirrels, and rabbits inhabit the burrows and tunnels they create in the soil.
Grasslands are also home to a variety of birds, including meadowlarks, sparrows, and hawks. Raptors such as eagles and falcons hunt over the open grasslands, while owls roost in trees and hunt at night.
Desert Biome
Deserts are arid regions that receive less than 25 centimeters of precipitation annually. They are characterized by extreme temperatures, sparse vegetation, and unique wildlife adaptations. Deserts cover about one-third of the Earth’s land surface and are found on all continents except Antarctica.
The climate of deserts is characterized by high temperatures and low humidity. During the day, temperatures can soar to over 50 degrees Celsius (122 degrees Fahrenheit), while at night, they can drop to below freezing. The lack of humidity means that deserts experience very little rainfall.
In some deserts, it may not rain for years at a time.
Vegetation, Biomes of north america pdf
The vegetation of deserts is adapted to the harsh conditions. Plants have deep roots to reach water deep in the ground. They also have thick, waxy leaves to reduce water loss through evaporation. Some desert plants, such as cacti, have spines to protect themselves from animals.
Wildlife
The wildlife of deserts is also adapted to the harsh conditions. Animals are active at night when temperatures are cooler. They have long legs to help them move quickly across the sand. Some desert animals, such as camels, have humps that store fat to help them survive during long periods without food.
Ecological Importance
Deserts play an important ecological role. They are home to a variety of unique plants and animals. Deserts also help to regulate the Earth’s climate by absorbing carbon dioxide and releasing oxygen.

Tundra Biome
The tundra biome is a vast, treeless expanse found in the Arctic and subarctic regions of North America. This cold, harsh environment is characterized by permafrost, a layer of soil that remains frozen throughout the year. The tundra is home to a unique assemblage of plants and animals that have adapted to the extreme conditions.
Climate
The tundra biome is characterized by a cold, dry climate. Temperatures can drop below -40 degrees Fahrenheit in the winter, and the average annual temperature is below freezing. The tundra receives very little precipitation, with most of it falling as snow.
The long, cold winters and short, cool summers make the tundra a challenging environment for life.
Vegetation, Biomes of north america pdf
The vegetation of the tundra is low-growing and sparse. The most common plants are lichens, mosses, and sedges. These plants are able to survive in the harsh conditions of the tundra because they have adapted to the cold, dry climate and the nutrient-poor soil.
Trees are absent from the tundra, except for a few stunted willows and alders that grow in the southernmost regions.
