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

In ecology‚ the competitive exclusion principle‚ sometimes referred to as Gause’s law of competitive exclusion or just Gause’s law‚ is a proposition which states that two species competing for the same resources cannot coexist if other ecological factors are the same. When one species has even the slightest advantage or edge over another‚ then the one with the advantage will dominate in the long term. One of the two competitors will always overcome the other‚ leading to either the extinction

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

A keystone species is defined as one that has a critical role in determining and maintaining the overall relationship of plants and animals within an ecosystem. If a keystone species is removed or declines‚ the nature of the ecosystem will change dramatically. Sea Otters — A Classic Keystone Species The classic tale of a keystone species is that of the sea otter‚ which was once found in abundance along the West Coast of North America. The story goes something like this: 1. European and

observed process of change in the species structure of an ecological community over time. Within any community some species may become less abundant over some time interval‚ or 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".

Communities and Ecosystems 37.1 Multiple Species Interact in Communities ~Communities are composed of coexisting populations of multiple species ~An ecosystem consists of a biotic community plus its abiotic environment ~Each species in a community has a place where it normally lives and a set of resources necessary for its life activities ~Ecologists describe the diversity of a community by measuring species richness and the relative abundance of each species. * Populations interact in many

2013 Foreign Invaders Invasive species are groups of organisms that are unnaturally occurring to an area. When introduced‚ they can cause economic and physical harm to humans and ecosystems. The importing‚ legally and illegally‚ of invasive species into our society is not only harmful to our population and our ecosystem but also the population of plants and animals in their indigenous homeland. To continue‚ the smuggling of plants and animals into new ecosystems is caused by a number of reasons

Since the appeared of the first life on this planet‚ numerous species come and go‚ rendered extinct by natural changes in physical and biological conditions. Because extinction is a natural part of the order‚ if there are many other species still exist‚ some people might wonders why or what so unique about the endangered species that large sum of money and effort is spent in order to save and restore them (Why

Ecosystem Components The Tarkine rainforest is located off Australia‚ on an island known as Tasmania. The Tarkine rainforest is the second largest temperate rainforest in the world. Temperate rainforests are extremely rare. It runs continuous for more than 70 kilometers and contains the Rapid‚ Keith‚ Donaldson‚ and Savage River systems. Globally‚ this is one of the most significant rainforests‚ which is temperate‚ left of the plant. The Tarkine rainforest contains three out four of Tasmania’s
