There are two types of rainforest biomes: tropical and temperate. Tropical rainforests are found near the equator and are moist and hot all year round. The climate in this biome is very humid‚ maintaining a high humidity of 77% to 88% all year round‚ due to the frequent rainfall. The rainfall is all year round and receive annual precipitation amounts from 60 to 160 inches. There is little to no seasonal changes in weather. The average temperature in tropical rainforests range from 70 to 85°F (21

Human Impact And Population The negative human impacts on harbor seals are devastating‚ and there are yet to be any major positive impacts. In the 1900s‚ fur traders would hunt harbor seal pups that were less than four weeks old for their fine coats‚ which were highly valued. This led to a decrease in the harbor seal population. Harbor seals were also hunted by salmon fishermen who saw the seals as competitors for the fish. After a while many harbor seal populations had to abandon traditional haul-out

Analyse the human impacts affecting the nature and rate of change of two ecosystems at risk. All ecosystems are placed under levels of stress that must be withstood or overcome in the form of evolution in order to adapt and survive. These attributes determine the resilience and vulnerability of each and every ecosystem. These forms of stress fall under two categories; natural and human induced. In regards to natural stress‚ the term gradual is used as it happens at a slower rate and lesser magnitude

world is currently undergoing changes unlike ever recorded before in human history. Record breaking temperatures are occurring more frequently‚ carbon dioxide (CO2) emissions are at their highest rates since the Jurassic period‚ and a rapidly increasing population‚ fully reliant on our planets natural resources‚ are beginning to push the earth to its limit. On a local level‚ these environmental changes are having a significant impact on California’s environment. If this trend continues‚ California could

Biomes- Marine and Tropical Rainforest The world is full of many different biomes. The ones I am most fascinated by are the tropical rainforest biome and the marine biome. Each is interesting in its own way. I have decided to narrow the marine biome down and focus on the Pacific Ocean. I am interested to see how these two compare and contrast. Although it may seem that our climate does not affect the marine biome‚ it does. During El Nino‚ the trade winds slacken and sometimes even change direction

A Biome is a large natural area on Earth where specific types of plants and vegetation grow. (Kalman‚ 1997). It is a large area where the form of life of climatic vegetation is uniform and also reflects the key features of the climate which also maps out the structural form and nature of the habitat for animals. (Odum‚ 1997). The climate‚ soil-types and animal life are all constituents of a Biome. There can be numerous ecosystems in any single Biome. This is due to the fact that there are many different
