Soils have been classified according to a system developed by soil scientists and the U.S. Soil Conservation Service. Using this classification system of soil orders, pick two locations on Earth, one in your current area and another area, and describe the order and the conditions that define it. (See Figure 4.12 in the textbook.)…

Taiga: a moist subarctic forest dominated by conifers (as spruce and fir) that begins where the tundra ends. The word taiga is of Russian origin, quite appropriate considering that a large part of the world’s taiga forests are located there. Taigas are also commonly called boreal forests and many of North America’s taigas are referred to as such. Taigas are found in Eurasia and in North America. They are characterized by the abundant presence of coniferous trees and poor soil due to the acidic needles that they drop.…

Jellyfish blooms have many negative effects on the ecology of the ocean and the economy of many places in the world. Seaside countries like Japan and Scotland have reported problems with finding jellyfish clogging water filters in their nuclear power plants. Compton's by Britannica states that a jellyfish's body has no skeleton and that more than nine tenths of it is jelly like. With that being said, one can see how these creatures may wind up obstructing seawater-fed pipes. Aside from the power plants, fishermen are affected as well, as the fish that they would normally catch can be devoured at a devastating rate by one of these blooms. These issues are a huge problem with long-lasting effects and can not be solved on their own without…

Nitrogen is the major component of earth's atmosphere. It enters the food chain by means of nitrogen fixing bacteria and algae in the soil. This nitrogen which has been fixed is now available for plants to absorb. These types of bacteria form a symbiotic relationship with legumes. These types of plants are very useful because the nitrogen fixation enriches the soil and acts as a natural…
Alaska continually amazes with its breathtaking scenery, diverse wildlife, and remarkable people. Alaskans have a wonderful knack for wanting to cherish and preserve the land they call home. Unfortunately, as invasive species have slowly started edging their way into our rivers, fields, and forests, many citizens are lacking the knowledge on how to properly combat this incursion and protect the state they reside in.

The golden mussel threaten one of the world's unique environmental systems. Up to now, it has reached the waters of five nations in South America. The golden mussel is a tiny animal that it does not grow more than 1 inch, and it releases tiny larvae that drift with the current to new areas. The golden mussels frequently stick to hard surfaces such as rocks, manufactured structures. The Golden mussels have already effected South America negatively, and it harmed innate clam species. In Brazil and Argentina, the Larvae and little mussels went into hydroelectric and water treatment plants, in addition, they are blocking channels, so the officials are forced to spend a lot of money to remove the mussels per year, and sometimes they kill the mussels…
