2. • An ecosystem is a geographic area where plants, animals, and other
organisms, as well as weather and landscape, work together to form
a bubble of life. Ecosystems contain biotic or living, parts, as well as
abiotic factors, or nonliving parts. Biotic factors include plants,
animals, and other organisms.

3. The different types of the ecosystem include:
•Terrestrial ecosystem. Forest ecosystem. Grassland
ecosystem. Desert ecosystem. Tundra ecosystem.
•Aquatic ecosystem. Freshwater ecosystem. Marine
ecosystem.

4. A terrestrial ecosystem is a land-based community of organisms and
the interactions of biotic and abiotic components in a given area.
Examples of terrestrial ecosystems include the tundra, taigas,
temperate deciduous forests, tropical rainforests, grasslands, and
deserts.

5. • What is a forest ecosystem? Forest ecosystems are areas of
the landscape that are dominated by trees and consist of
biologically integrated communities of plants, animals and
microbes, together with the local soils (substrates) and
atmospheres (climates) with which they interact.

6. • Grassland Ecosystem is an area where the vegetation is
dominated by grasses and other herbaceous (non-woody)
plants. It is also called transitional landscape because
grassland ecosystems are dominated by the grass with few or
no trees in the area where there is not enough for a forest and
too much of a forest

7. • An aquatic ecosystem includes freshwater habitats like lakes,
ponds, rivers, oceans and streams, wetlands, swamp,
etc. and marine habitats include oceans, intertidal zone,
reefs, seabed and so on. The aquatic ecosystem is the habitat
for water-dependent living species including animals, plants,
and microbes.

8. • Deserts are barren areas of land characterised by extremely
high or low temperatures, with low rainfall and scarce or no
vegetation. Deserts are examples of terrestrial ecosystems,
which are found throughout the world.

9. • Tundra ecosystems are treeless regions found in the Arctic
and on the tops of mountains, where the climate is cold and
windy, and rainfall is scant. Tundra lands are covered with snow
for much of the year, but summer brings bursts of wildflowers
