The terrestrial world can be divided into areas called biomes. A biome is a large area of land classified by its plants and animals. A biome is made up of many ecosystems. An ecosystem is the interaction of living and nonliving things in an environment. In this backgrounder, major terrestrial biomes of the world are named based on the Whittaker cla...
The map below shows where each of the eight major terrestrial biomes are located in the world. Canada contains four biomes. These are temperate deciduous forest, grassland, boreal forest/taiga, and tundra. A biome has the same characteristics no matter where in the world it is found. This means that the boreal forests of Canada look like the boreal...
Location
The boreal forest covers about 11% of Earth’s land mass. This makes it the world’s largest terrestrial biome! It is located in the northern hemisphere. It extends from around 50° North latitude to 65° N latitude. The term “boreal forest” tends to refer to the southern part of the biome. The term “taiga” tends to refer to the northern part of the biome. This is where it transitions to the Arctic tundra biome.
Description
This biome has many coniferous forests. It also has a lot of freshwater ecosystems including rivers, streams, ponds, lakes, bogs, fens and marshes. The soil in this biome haslow fertility. This means that it is not very good for plants. Most of the nutrients are only in a thin layer on the surface of the ground. This soil is also acidic. This is mainly due to the breakdown of needles that fall from coniferous trees. The boreal forest has cold winters and warm summers. Typical temperatures ran...
Plants & Animals
Some of the trees found in this biome include conifers such as spruce, fir, hemlock, larch and pine. There are also some deciduoustrees, such as aspen, birch and willow. The mix of trees depends on which part of the world the forest is in. The boreal forest of North America is mostly spruces. Smaller mammals, such as beavers, raccoons and voles also live here. Many species of birds use this biome for their nesting grounds. Lakes and rivers provide a unique habitat for many migratory fish such...
Unlike adult frogs, tadpoles can’t go on land – so they feed on plant material filtered from the water, and tear off tiny chunks of nearby vegetation. The legless, water-bound tadpoles slowly metamorphose into frogs over the next 14 weeks. First, they grow back legs, then front legs too!
Jun 10, 2023 · In most species, the frog life cycle includes eggs, tadpoles, and adults that then lay and fertilize eggs. The frog life cycle involves dramatic transformations – a process known as metamorphosis. Learn about the intricate stages of frog metamorphosis from the egg to tadpole into the adult frog.
