My favorite biome

I would have to say, that the most interesting biome i find is the rainforest! It has a large ecosystem supporting a biodiversity of plants and animals! Not only that, but many of these plants contain medicines that we could use. Also, the amount of rainfall in the forest is enourmous! About 68-78 inches of rain a year! What many people don't know, is that their are two types of rainforests. The tropical rainforest that we all think about, and the temperate rainforest. Tropical rainforests are said to be the Earths lungs, but its found that that tropical rainforests contribute little net oxygen to the atmosphere through photosynthesis. And despite the amount of rainfall, soil quality is quite poor! Yet the rainforests can sustain more then half of the worlds species of plants and animals! This is why i find that the rainforests are so interesting!

River habitats

A river is a body of flowing water that goes into a sea, lake, or ocean. The crenon is the uppermost zone at the source of the river. It is further divided into the eucrenon (spring or boil zone) and the hypocrenon (brook or headstream zone). These areas are characterized by low temperatures, reduced oxygen content and slow moving water. The rhithron is the upstream portion of the river that follows the crenon. It is characterized by relatively cool temperatures, high oxygen levels, and fast, turbulent flow. The potamon is the remaining downstream stretch of river. It is characterized by warmer temperatures, lower oxygen levels, slow flow and sandier bottoms. The chemistry of the water has a large impact on the ecology of that water for both plants and animals and it also affects the uses that may be made of the river water. Flooding is a natural part of a river's cycle also. 

Semester 2: Relationships between organisms

Their are many organisms that help each other in the act of survival. One example that happen on campus is below the soil. Their are worms in the soil, that eat the dirt, and their poop thus gives nutrients to the soil. This leads to my next example, which is plants and trees take nutrients from the dirt and make food with that such as fruit. This fruit feed herbivores or omnivores such as the rats or opossum in the school. Not only do the plants and trees feed them, but we humans also give them our left over trash. This attracts carnivores, for example, the hawk that circles over ricks. This hawk hunts the rats and opossums that live in our school. Our school is able to support many animals and creates a variety of relationships between organisms that support their survival.
