Introduction Mangroves are ecologically and economically important as a natural renewable resource (Field 1995). They are considered productive ecosystems and important source and sink of carbon within the tropical coastal zone (Twilley et al. 1992; Ong 1993; Alongi 1998). The ecological processes in mangroves (productivity‚ nutrient cycling‚ litter dynamics‚ succession and sedimentation) make them most productive ecosystems in the coastal region (Clough & Attiwill 1982; Hutchings & Saenger

Aquatic plants: Fixed plants Fixed plants are held in place by their roots which grow in the water-bed. The Water Lily and Lotus are such plants. Their stems are long‚ hollow and light. These stems reach the surface of the water. The leaves and flowers‚ which grow from the top end of the stems‚ float upon the water. The leaves are broad with stomata on the top surface so that the water does not block them. Lotus The roots of lotus are planted in the soil of the pond or river bottom‚ while

Pollination is service provided by insects and other small animals. Also Honey-bees distribute pollen among plants of the same species. This function of ecosystem could not be imitated by any jet invented technology. Plants

------------------------------------------------- Aquatic animal From Wikipedia‚ the free encyclopedia An aquatic animal is an animal‚ either vertebrate or invertebrate‚ which lives in water for most or all of its life.[1] Some examples of invertebrates are coelenterates. This phylum consists of jellyfish‚ anemones‚ corals‚ and hydras. Another type of invertebrate aquatic animal is the annelids which are segmented worms. There are three different classes they are polychaetes‚ oligochaetes‚ and

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

Veterinarians help to maintain the health of animals and work to recover their health. They diagnose and treat medical conditions of pets and other animals. Veterinarians can specialize in many different areas. Marine-life‚ or aquatic veterinarians specialize in the health of aquatic animals. Some animals they work with include fish‚ sea turtles‚ dolphins‚ stingrays‚ whales and in some cases sharks. Veterinarians must be very skillful in many different areas. The most important skill a vet needs is a passion

together in a setting” (Simon‚ Reece‚ and Dickey‚ 2010). There are two main types of aquatic ecosystems‚ freshwater and marine. The main difference between them is that marine ecosystems contain salt‚ which causes them to be undrinkable without substantial alterations. Freshwater systems contain nearly no salt and provide a majority of the Earths’ drinking water‚ with little alterations. Freshwater ecosystems are aquatic systems that include both abiotic and biotic components. Abiotic components are

Aquatic Invasive Species Two thirds of the forty freshwater fish extinctions are known to have been caused by invasive species. The extinctions could have been caused by any one of the four thousand three hundred known invasive species in the United States. In Minnesota‚ the land of ten thousand lakes‚ thirty-five percent of all recreational waters are known to hold at least one invasive species (Invasive species of aquatic plants and wild animals in Minnesota: Annual report).
