The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. All other sub-ecosystems fall under these two. Arid and semi-arid systems2. 25% of our coral reefs have disappeared and it is expected that 60% more will be gone in 30 years. If the ecosystem exists in a water body, like an ocean, freshwater, or puddle, it is called an aquatic ecosystem. These are: 1. As these borders are never rigid, ecosystems tend to blend into each other. Desert Ecosystem 6.

It is a medium scale ecosystem such as a forest or a large lake. environmental or the ecological area in which an organism inhabits An ecosystem consists of all the living and non-living things in a specific natural setting. Marine ecosystems can be divided into many zones depending upon water depth and shoreline features. In the world, there are several ecosystems working at macro or micro level. In temperate zones, forest ecosystems may be deciduous, coniferous or oftentimes a mixture of both, in which some trees shed their leaves each fall, while others remain evergreen year-round. Freshwater ecosystems are home to more than just fish: algae, plankton, insects, amphibians and underwater plants also inhabit them. The benthic zone consists of substrates below water where many invertebrates live. The term “tundra” most commonly denotes polar areas, but at lower latitudes, tundra-like communities known as alpine tundra may be found at high elevations. Sunlight affects the ecosystems because it determines what types of plants will grow in that habitat.

Plants, animals, insects, microorganisms, rocks, soil, water and sunlight are major components of many ecosystems. We now have over 2bn iOS and Android devices on earth, and this will grow in the next few years to well over 3bn. Ecosystem ecology studies the processes and dynamics of ecosystems, and the way the flow of matter and energy through them structures natural systems. Ecosystems come in three types. CLICK HERE to see how the tree trunk ecosystem works. Scientists call this blending “ecotone”. Agricultural systems Forest ecosystems are classified according to their climate type as tropical, temperate or boreal. 2. Six major ecosystems of the world are as follows: 1.

Grasslands share the common climactic characteristic of semi-aridity. They are subdivided into two classes: those in which the water is nearly stationary, such as ponds, and those in which the water flows, such as creeks. This ecosystem has variety of life such as flora and fauna. Looking at the world as a whole, there are essentially two major types of ecosystems. Ecosystem boundaries are not marked (separated) by rigid lines. Rain-forest Ecosystem. As with deserts, a harsh environment characterizes ecosystems in the tundra. The Encyclopedia of Global Warming and Climate Change, Volume 1 identifies eight major ecosystems: temperate forest, tropical rain forests, deserts, grasslands, the taiga, the tundra, the chaparral and the ocean.
