role in global ecology. Each ecosystem consists of important aspects including nutrients cycling‚ biodiversity‚ and energy flow that contribute to the overall state of the ecosystem. However‚ the limited nature of aquatic ecosystems provides distinctions from terrestrial ecosystems (Reece et al. 2010). The limiting nature of light in nutrients of an aquatic ecosystem has an overall effect on biodiversity‚ nutrients cycling‚ and energy flow. Biodiversity plays a major role in aquatic ecosystem success

of clean drinking water and the decomposition of waste. Natural ecosystem services is split into four categories: provisioning‚ such as the production of food and water; regulating‚ such as the control of climate and disease; supporting‚ such as nutrient cycles and crop pollination; and cultural‚ such as spiritual and recreational benefits. 6. An environmentally sustainable society is a community that is in balance with nature; people in the society do actions that are good for the environment.

and transfer of heat energy across the globe. The movement of this heat through local and global ocean currents affects the regulation of local weather conditions and temperature extremes‚ stabilization of global climate patterns‚ cycling of gases‚ and delivery of nutrients and larva to marine ecosystems. Ocean currents are located at the ocean surface and in deep water below 300 meters. They can move water horizontally and vertically and occur on both local and global scales. The ocean has an interconnected

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 1987; Aksornkoae 1993). The uses and values of mangroves are linked to their ecological functions

If there isn’t enough light or water or if the soil doesn’t have the right nutrients‚ the plants will die. If the plants die‚ animals that depend on them will die. If the animals that depend on the plants die‚ any animal that depends on those animals will die. Ecosystems in nature work the same way. All the parts work together to

It can also be defined as Vegetable and livestock production using natural sources of nutrients (such as compost‚ crop residues‚ and manure) and natural methods of crop and weed control‚ instead of using synthetic or inorganic agrochemicals. It is also called low input farming. Many kinds of farm products are produced organically including
