Ecosystem

WHAT IS ECOSYSTEM An ecosystem consists of the biological community that occurs in some locale, and the physical and chemical factors that make up its non-living or abiotic environment. There are many examples of ecosystems -- a pond, a forest, an estuary, grassland.  The study of ecosystems mainly consists of the study of certain processes that link the living, or biotic, components to the non-living, or abiotic, components. Energy transformations and ecosystem components are the two main topics...

 Environmental Impacts on Ecosystems Introduction An ecosystem is a community of living organisms (plants, animals and microbes) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. Ecosystems are controlled both by external and internal factors. Once outside factors affect these...

Ecosystems

Ecosystems – Grassland vs. Mountains Every single day, we breathe in air and take a look at the green grass, we taste the blue water, we subconsciously analyze the soil, feel grey rocks, look down on small insects, watch the growing trees, the flying birds, and even ourselves, the people. But all of these elements do not exist just to be there, they have a further important meaning interacting with organisms. We are talking about a biological community of interacting organisms and their physical...

Ecosystems and their functioning

Ecosystems at Risk Ecosystems and their functioning What is an ecosystem? Ecology – the science that examines the interactions between organisms and their living (biotic) and non-living (abiotic) environment. Groups of organisms and their biophysical environment interact and exchange matter and energy. Ecosystem – the dynamic complex of plant, animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are dynamic; constantly changing and adapting...

marine ecosystem

Marine Ecosystems are the largest systems on the planet, covering over 70 percent of the Earth's surface and constituting over 99 percent of the living space on the planet (area x depth). These vast ecosystems are composed of many different habitats which extend from the near shore regions to continental shelves and the deep ocean. They are home to millions of species and provide food, income, protection, and many other vital ecosystem services to billions of people around the world. ECOLOGICAL...

Ecosystem Succession

they may even vanish from the ecosystem altogether. Similarly, over some time interval, other species within the community may become more abundant, or new species may even invade into the community from adjacent ecosystems. This observed change over time in what is living in a particular ecosystem is "ecological succession". why it occurs Every species has a set of environmental conditions under which it will grow and reproduce most optimally. In a given ecosystem, and under that ecosystem's...

Ecosystems at Risk

the functioning of TWO different ecosystems at risk.’ An ecosystem is the dynamic complex of plant, animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are systems through which incoming solar energy is captured and channelled through a hierarchy of life forms. Each ecosystem has its own characteristic plant and animal community. Nature of change refers to the natural or human induced change towards an ecosystem. Humans play a role in maintaining...
