ECOLOGY
Ecology is the study of ecosystems and how organisms live, survive, and interact with each other and their environment. Their are a virtiety of ecosystems on earth. These ecosystems, areas that contain interacting population; including abotic components, are determined by . Bioshpheres are living parts of the earth that could sustain life and these are broken down into biomes. Biomes are determined by the climate related with latitude and the equator. Biomes consist of tropical rainforest, desert, savanna, temperate forest, taiga, and tundra. In a tropical rainforest there are Venus fly traps, pitcher plants, toucans, monkeys and frogs. In a deset there are cactus, camels, and armadillos. In a savanna there is grass,hyena, graffis and elephants. In a temparate forest there are maple tress, sunflowers oak trees, deer, and fox. In a taiga there are maple trees, pine trees, wolfs, fox, moose, rabbits , and pigeons. In tundra there are no plants, however, there are polar bears, seals, penguins, and walrus.
Community interaction occurs in an ecosystem. Predator/Prey relationship consist of a predator, like a cheetah, which is an organism that captures and feeds on another organism. A prey is an organism like a gazelle that is capture and eaten Symbiosis is any relationship in which two organisms live closely together. The three main classes are mutualism, commensalism, and parasitism. In mutualism both organism benefit. In commensalism one organism benefits where as the other is not harmed nor helped. In parasitism one benefits where the other is harmed or does not benefit. A competition is also a community interaction. In a competition organisms same or different attempt to use an ecological resource in the same place at the same place at the same time. The competition exclusive principle states that no species can occupy the same niche in the same habitat at the same time. For example, in a forest an oak tree and a hickory may compete for sunlight by spreading their leaves.

The Atlantic Sturgeon
The Atlantic Sturgeon prefers estuaries and rivers during spawning season. They spend most of their lives in estaurines and marine water. They spawn in moderately flowing water, 46- 76 cm/s in large rivers. Their eggs are adhesive and are deposited on hard surfaces like cobble. The eggs need cold, clean water to develop properly in their larval stage.One one larvae begins to migrate, they use benithic structures such as gravel matrices as refuge, while Atlantic Sturgeons in their juvenile stage stay in estaurines for many months and even years[2]. When the adults are not spawning the remain in coastal water and estuarines that are shallow, 10-50 miles in depth, that are filled with gravel and sand [2].
The Atlantic Sturgeon is a bottom dwelling aquatic organism that feeds on mollusks, worms, snails, crustaceans, small fish and other invertebrates[1]. The Atlantic Sturgeon can be at any tropic level. They consume Mollusk which are herbivores on the 2nd tropic, small fish that are in the 3rd tropic level, and crustaceans on the 4th tropic levels. Due to their scutes, the Atlantic Sturgeon has no predators other than humans.
A niche is an organism purpose, job, role, or place in a habitat. The Atlantic Sturgeons niche in their ecosystem is to eat plants and animals in the water. Their waste also fertilizes the plants growing at the bottom of rivers and estaurines. The Atlantic Sturgeon also provides food for humans and even their eggs are used for caviar. There is very little documentation of the Atlantic Sturgeons interaction with other organisms. However, the Atlantic Sturgeon is a bottom-feeding organism, making it possible for the Atlantic Sturgeon to compete with other bottom-feeding organisms for bottom-dwelling species as food[3].
