growth and reproduction of all organisms have a limited quantity on earth at any one time‚ other than the occasional meteor that brings with it new matter. It is therefore important that the recycling of these chemical elements is efficient. Autotrophs are the basis of almost all ecosystems. The rate that autotrophs produce and transfer energy is vital to the capacity of organisms that can inhabit these ecosystems. To understand the rates in which certain species’ leaves decay and release the energy

What is the Marine Ecosystem? Marine ecosystems are among the largest of Earth’s aquatic ecosystems. It covers almost 70% of the earth’s surface. They include oceans‚ salt marsh and intertidal ecology‚ estuaries and lagoons‚ mangroves and coral reefs‚ the deep sea and the sea floor. They can be contrasted with freshwater ecosystems‚ which have a lower salt content. Why is the Marine Ecosystem important? Marine ecosystems are very important in to the overall health of both marine and terrestrial

These components affect living organisms in many ways. Some of the soluble components and emulsions are poisonous‚ particularly to small organisms that do not have protective coverings or shells- Fish larvae‚ single celled algae and many kinds of plankton are vulnerable and these are the basic foundation of the marine food chain. In shallow water these toxic substances may directly kill algae‚ coral and sea grasses. These components may also be passed in the food chain or directly ingested or absorbed

Human activities that may affect water ecosystems such as oceans FISHING Reducing the fish communities in rivers and oceans‚ destructive fishing techniques can also cause water pollution and damage to coral and other aquatic life. Destructive fishing techniques involve the use of dynamite or cyanide; trawling in coral-rich ecosystems; bottom trawls that are dragged along the ocean floor‚ also disrupt and damage critical habitats.

The period of 1492-1750 opened up new worlds and old worlds to a world of growing interdependence and connectivity. This era was home to the discovery and subsequent European colonization of the Americas and the African slave trade (the diaspora) both being remarkable and profound events in world history. The interactions focused on three regions: Western Europe‚ Africa‚ and the Americas. The communication expanded the economies of all three regions while damaging social structures of Africa and
