Nutrients in the soil are essential to the proper growth of a land plant. This tutorial deals with the properties of soil and the factors (i.e. climate, parent material, local topography, vegetation, living organisms, and time) that brought soil to what it is today. ..
Animals living in aquatic habitats have diversified and evolved through time. They eventually occupy ecological niches available in the ecosystem. Three regions exist in a freshwater environment: profundal, pelagic, and benthic. Get more information on each of these regions and how these regions led to the varying niches that freshwater animals eventually occupied...
The water cycle (also referred to as the hydrological cycle) is a system of continuous transfer of water from the air, sea land, and water in a cycle. This tutorial explains in brief what occurs in the water cycle. Also, it delineates what is groundwater and surface run-off. This is an essential background as to how the water moves in an ecosystem both geologically and biologically...
This tutorial noted some of the physical and chemical factors that provide the framework of a running water community in which organisms in their favored ecological niches occupy. Learn how each of these factors affects lotic communities in this tutorial...
If New Zealand has lots of unique animals, it's also got a whole lot of unique plants. Find out more about some of them, and the roles they play in different natural ecosystems...
Learn about community patterns and the ecological factors influencing these patterns. Revisit some of the ecosystems you've learned about earlier to learn more about the possible impacts of natural and human-induced environmental changes...
