Types of Ecosystems
Natural Ecosystems
These operate by themselves under natural conditions without any major interference by man. Based upon the particular kind of habitat, these are further divided as:
1. Terrestrial, e.g. forest, grassland, desert
2. Aquatic which is further distinguished as:
a. freshwater which may be Iotic (spring, stream or river) or lentic (lake, pond, pools, ditch, swamp, etc.)
b. Marine, e.g. sea or ocean (deep bodies) and estuary (shallow bodies).
