Solution:
TYPES OF ECOSYSTEM:
Ecosystem varies greatly in size from a small pond to a large forest or a sea. Many ecologies regard the entire biosphere as a global ecosystem as a composite of all local ecosystem on earth. Since this system is too much big and complex to be studied at one time, so to make the study easier, it is broadly divided into two basic categories. i) Terrestrial Ecosystem: It occurs over land e.g., forest, grassland, desert. ii) Aquatic Ecosystem: It occurs in water bodies e.g., pond, lake, river (freshwater), wetland, sea, estuaries (salt water).
Similarly, w.r.t. human interference the ecosystems are of two types: i) Natural ecosystem: It develops in nature without human support or interference e.g., forests, marine ecosystem. ii) Anthropogenic ecosystem or man-made ecosystem: It is the one which is created and maintained by human beings e.g., crop fields, garden, aquarium, Agro ecosystem or agriculture is the largest manmade ecosystem.
