layers and long days that extent 24 hours for months on end‚ the Arctic Ocean is very fruitful. This productivity starts as phytoplankton‚ microscopic fast growing and reproducing plants that live in the top layer of the ocean. These are eaten by zooplankton. Then so on and so forth which feeds the fish that then feeds the mammals. Most artic mammals are warm blooded animals‚ known as endotherms‚ and they maintain similar internal body temperatures to warm blooded animals in any other climate zone

provides a conservation area for mammals‚ insects‚ amphibians‚ reptiles and over 380 species of birds‚ some of which are highly endangered. During the field trip‚ we visited five different habitats‚ including fishponds‚ mangroves‚ reedbeds‚ freshwater ponds‚ gei wai(tidal shrimp ponds) and mudflat. The trip not only helped us understand more on how organisms interdependent and interact with their physical environment to form an ecosystem‚ but also allowed us learn about how sustainability and

County. Intrusion of saltwater occurs when the demand or increase in the pumping of freshwater wells is higher than the rate at which freshwater naturally produces. The production rate for freshwater takes time and depends on a few factors such as the climate‚ precipitation‚ surface runoff‚ and temperatures affect the rate at which freshwater accumulates. When over pumping occurs and the underground freshwater process is slow‚ ocean water replaces the absent ground water and thus areas suffer saltwater

Herbivores: Level 2 of the trophic chain consists of organisms that consume primary producers. Such species are often termed herbivores. Herbivores may be very small organisms such as zooplankton that graze on microscopic plants such as phytoplankton; however‚ herbivores also include many enormous mammals such as rhinoceri and elephants. If significant numbers of the herbivore trophic level are removed‚ plant growth may exceed the balance found in the previous natural environment. For example the

Increasing demands from agriculture‚ industry‚ and an expanding population have resulted in important habitats across the world left to deteriorate. “On March 20‚ 2000‚ a crowd of monkeys‚ driven mad from thirst‚ came into conflict with desperate villagers over drinking water in a small station located in a sparse population

salt water freezes later than freshwater. The exact measurement of how they impact each other is this: every 5 psu increase‚ the freezing point decreases by 28%.. In an ocean‚ there is frazil and brine. Frazil are ice crystals suspended in water‚ and they are made of nearly pure freshwater. Frazil is the first stages of the growth of sea ice. Brine are salt droplets. Sometime brine can get trapped in frazil. Since all salt pools together for brine and all freshwater accumulates for frazil‚ frazil

Temperature and precipitation shifts directly affect biota‚ and scientists think that as the climate continues to change‚ the biodiversity in Northern Canada is particularly at risk. Because global warming can result in the decreasing of marine‚ freshwater and terrestrial communities‚ climate change has negative influences on biodiversity in Northern Canada. In order to conserve the biodiversity and improve the global warming‚ Canadian governments and schools have devoted to take actions on climate
