There are three different types of ecosystems: natural ecosystems, man-made ecosystems, and micro-ecosystems. This article describes the characteristics of an ecosystem, subcategories for each type of ecosystem, and examples with illustrations.
Surface structure and size of the objects were other factors which determined substrate selection by these organisms. Leeches more readily inhabited rough surfaces and the surfaces of smaller-sized objects. The species composition of leech assemblages on analysed artificial substrates was dominated by ...
The forest's moisture loving animals include the giant flatworms. They glide across damp soil blanketed with leaves, where leeches cling in wait for passing animals. South America's bird-eating spider and Hercules beetle are among the largest creatures of their kind. Stick insects, crickets, bu...

The ocean is recorded to cover about 70% of the earth’s surface and 97% of the water used on earth. Oceans are quite vital for life on earth as they control the various weather patterns ass well as the earth’s climate. They also serve as a habitat for over 230,000 species within...
In recent decades, there has been a decrease in the diversity of aquatic taxa, leading to increasingly uniform communities. Many species have become rare, vulnerable, or endangered, and their distribution has been drastically changed. Local extinctions of indigenous taxa sensitive to changes in enviro...
