- Introduction to The Sorption of Chemical Constituents in Soils
Soils are dynamic and diverse natural systems that lie at the interface between earth, air, water, and life. They are critical ecosystem service providers for the sustenance of humanity.
In exploring the link between soil and agriculture, this article will highlight 1) our transition from hunter-gatherer to agrarian societies; 2) the major soil properties that contribute to...
- The Terrestrial Biomes
- Distribution of The Earth’s Major Biomes
- Boreal Forest/Taiga
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...
Aug 11, 2022 · Soils in very cold areas with permafrost conditions (such as the arctic tundra) tend to be shallow and weakly developed due to the short growing season. In warm, tropical climates, soils tend to be thicker (but lacking in organic matter), with extensive leaching and mineral alteration.
Oct 19, 2023 · A biome is an area of the planet that can be classified according to the plants and animals that live in it. Temperature, soil, and the amount of light and water help determine what life exists in a biome. A biome is different from an ecosystem. An ecosystem is the interaction of living and non-living things in an environment. A biome is a ...
Sep 6, 2024 · An ecosystem is a geographic area where plants, animals and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living parts, as well as a biotic factors , or nonliving parts.
