There are a couple different types of biomes. There are six major groups of biomes which are; freshwater‚ marine‚ desert‚ forest‚ grassland‚ tundra. Then these six groups are broken down a bit father. In this paper we will discuss part of the marine biome which is the ocean biome. When one thinks of very large bodies of water such as the ocean‚ we are talking about marine biomes. Instead of freshwater it contains saltwater. They also include the coral reefs and estuaries. The ocean biome is the

For instance‚ sea water intrusion into our islands is causing our crops to die and our freshwater to be contaminated. Slowly and surely we are losing our food and our freshwater. Inch by inch‚ centimeter by centimeter our islands are being washed away by the rising tide. It is for the urgent addressing of these serious threats that the upcoming Mauritius International Meeting on the

Ocean‚ each species has a unique appearance and has different habitats but they share many characteristics. Salmon are also a very unique species‚ they are anadromous‚ meaning that their eggs are laid and hatch in freshwater‚ and their youth spend some of their early lives there in freshwater before swimming to the ocean to grow and mature. Pacific salmon spawn only once and dies within days of digging their nest and mating. Their bodies will float down the stream and decompose‚ filling the water will

As in other species in the genus Diodon‚ this swelling causes the erection of the long movable spines covering the body.

Johnny Izaguirre Professor Orshan ENC1101 June 19‚ 2013 Eat less Meat As reported in 2007‚ 275 million tons of meat were produced worldwide. This is enough meat to supply everyone with 92 pounds of meat. What does this statistic really mean? We will find that the mass consumption of animals is a primary reason why humans are hungry‚ overweight‚ or sick. Also a leading cause of the depletion‚ and pollution of water‚ the degradation and deforestation of natural forest. While causing extinction of species

• Forests Forests is not just made of trees but also animals and micro-organism. Throw into the mix the non-living‚ abiotic components like soil‚ climate and water‚ and take in the complex interrelationships among the organisms and the environment‚ and we are closer to an actual understanding of this ecosystem. With one third of the Earth’s surface is covered with forests it is no surprise that they are among the most notable storehouses of biological diversity on the planet. Forests have a

River pollution also leads to decrease in freshwater resources because rivers are among most important sources of freshwater in the world. This means that the excessive river pollution could easily lead to global water shortage. Excessive river pollution could also lead to many waterborne diseases. Pollution can be in a variety of
