Restoration of the Everglades Everglades or, ‘the river of grasses’, are a vast expanse of freshwater marshes which extends from Lake Okeechobee South to the tip of Florida. There are various forms of habitat that exist on the marshland-open water sloughs, open water sloughs, cypress swamps, hard wood hammocks, mangrove swamps and pinelands. It is also home to many species such as the black bears, panthers, alligators some of which are on the verge of extinction (Ichthyology, n.d). The flora

be damaging to the external environment. Natural sources, which emit sulfur dioxide, are volcanoes, sea spray, rotting vegetation and plankton. Acid rain is destroying the world’s lakes, air and ecosystem. Acid rain affects every single aspect of the ecosystem. Acid rain is devastating to aquatic life, crops and forests, and human life. People exposed to sulfur dioxide in the air often have reduced lung function. The growth of forestlands also shows the effects of acid rain. Acidic rain damages

Daphnia are small planktonic crustaceans that belong to the Phyllopoda (sometimes called Branchiopoda), which are characterized by flattened leaf-like legs used to produce a water current for the filtering apparatus. Within the branchiopods, Daphnia belong to the Cladocera, whose bodies are enclosed by an uncalcified shell known as the carapace. It has a double wall, between which hemolymph flows and which is part of the body cavity. The carapace is largely made of chitin, a polysaccharide. Cladocera

labs. Lab Alternatives – Computer Based p. 113 Exercise 1 – Phylum Porifera – Sponges Given that all sponges are filter feeders, why does it follow that all sponges are aquatic? Filter feeding is the filtering of nutrients and plankton suspended in water therefore for sponges to feed effectively they must be aquatic Would mobility improve the ability of sponges to capture food? Explain. Mobility would improve the action of the sponge, help it to capture food because it has a hard thing
