North America's humid continental climate region is located in the northeastern and midwestern parts of the continent. It is characterized by distinct seasons with cold winters and warm summers, as well as moderate precipitation throughout the year. The region also experiences a wide range of temperatures, from freezing in winter to hot in summer, with an annual average temperature of around 50°F (10°C).
In this climate region, coniferous and deciduous forests dominate the landscape, with trees such as maple, oak, pine, and spruce being commonly found. The region is also home to various bird species, including the ruby-throated hummingbird and the bald eagle. Mammals such as white-tailed deer, black bears, and gray wolves are also present.
Moving on to the grassland ecosystem, which is found mainly in the central part of North America, some of the plants commonly found include prairie grasses like big bluestem, little bluestem, and switchgrass. These grasses have deep root systems that help them survive in the dry conditions of the grassland. Other plants found in this ecosystem can include wildflowers, such as coneflowers and goldenrods.
Regarding animals, the grassland ecosystem supports various species, including the pronghorn antelope. This mammal is known for its incredible speed, as it is the fastest land mammal in North America. Another animal found in grasslands is the burrowing owl, which makes its nests in abandoned prairie dog burrows. These owls are known for their unique behavior of standing outside their burrows during the day.
