Full Answer

Ecosystems are based upon the interactions between groups of species, the individuals within them and the processes of their respective lives. Ecosystems involved the interaction of everything from the simplest plants to the complex human world. After ecosystems comes organisms, and this includes every living thing from bacteria to animals. Next are the organ systems, which are the various systems that make it possible for living things to undergo the processes they need to live, such as the reproductive system. Next come organs, which are the individual parts of the organ systems. In descending order of size we then have cells, molecules and then atoms.

    What are some major dynamic processes that can take place in ecosystems?

    A:

    Some of the dynamic processes that can occur within an ecosystem are flooding, temperature changes, vegetation growth, invasions by non-native species and human intervention. In riparian ecosystems, such as floodplains, the role of human intervention can be significant as man-made structures such as levees, dikes and dams alter the course of water flows and flood pulses. Hydrologic alterations are an example of how changes made to an ecosystem carry the potential to disrupt critical nutrient cycling, change seed dispersal patterns and hamper the establishment and growth of vital plant communities.
