Aquatic Biomes An aquatic biome is an ecological community dominated by water. This biome can be broken down into two categories: o Freshwater‚ which includes rivers‚ streams‚ ponds‚ lakes and freshwater wetland. o Marine or saltwater‚ which includes oceans‚ seas‚ estuaries‚ coral reefs and saltwater wetland. Each of these aquatic ecosystems can be defined by variables such as temperature‚ the presence or absence of light‚ and the availability of nutrients. Aquatic biomes cover almost all the

An aquatic animal is an animal‚ either vertebrate or invertebrate‚ which lives in water for most or all of its life.[1] It may breathe air or extract its oxygen from that dissolved in water through specialised organs called gills‚ or directly through its skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land). Animals that move readily from water to land and vice versa are often referred to as amphibious. The term aquatic can in theory

Rachel Harrison presents… The Aquatic Ape Theory! The aquatic ape theory is an alternative explanation of human evolution that suggests modern man spent some time adapting to a semi-aquatic environment before taking on its current form. This idea was first proposed in 1942‚ and its greatest proponent since that time has been Elaine Morgan. The aquatic ape theory‚ although compelling‚ has failed to become accepted within the scientific community. Max Westenhofer first published an account of

living in an aqueous environment compared to a terrestrial one? Introduction: Plants are commonly classified to two main types: aquatic plant and land plant. They have different features to adapt the living environment. What by meant is that they require different adaptions to stay alive in their respective environment such as humidity and structure of leaves. Aquatic plants referred to as hydrophytes or macrophytes. They need a special adaptation to live in water or at water surfaces and the most

These plants may be totally submerged beneath the lake surface‚ floating‚ or growing along the shoreline. They provide food and shelter for bugs‚ fish and other organisms‚ prevent shoreline erosion‚ filter pollutants from adjacent shoreline activities‚ and

You will be graded on how accurate your information is as well as neatness." Sponges (Porifera): Poriferans don’t have mouths; instead‚ they have tiny pores in their outer walls through which water is drawn. Cells in the sponge walls filter nutrients from the water as the water is carried through the body

Imagine‚ being an animal locked in a to small cage‚ poisoned with cancer‚ drugged‚ and wishing you were dead. Animals being tested on have all these bad things happening to them and much‚ much‚ more. Many products such as cosmetics‚ chemicals and even bath products are tested on animals. Sometimes it gets in their eyes and can harm them enough to make them lose hair or even their lives. On the other side of the debate‚ people will argue that people should be allowed to experiment on animals because it helps
