There are four major types of ecosystems: grassland, forest, aquatic, and desert. Each ecosystem is defined by its biotic and abiotic factors. Biotic factors include living organisms, while abiotic factors include non-living elements like air, soil, water, and sunlight. Ecosystems are classified based on these factors and provide important functions such as purifying water, recycling nutrients, and supporting biodiversity.

• Ecosystem
• Major four types
• Grassland Ecosystem
• Aquatic Ecosystem
• Forest Ecosystem
• Desert Ecosystem

3. Ecosystem
• An ecosystem is a biological environment
consisting of all the living organisms or Biotic
component, in a particular area, and the
nonliving, or Abiotic component such as
air, soil, water and sunlight with which the
organisms interact

5. Biotic Abiotic
• Sunlight • Primary producer
• Tempreture • Hervivorus
• Precipitatio • Carniorous
• Water or Moisture • Omnivorus
• Soil or Chemical content • Detritivorous

7. Forest Ecosystem
• High rainfall
•Large number of organism and
flora
• Highly diverse population
• Stability of ecosystem is very
sensitive

8. Types of Forest
• Tropical evergreen forest
• Tropical deciduous forest
• Temperate evergreen forest
• Temperate deciduous forest
• Taiga

9. Features of Forest Ecosystem
• Forest canopy
• Forest floor
• Forest soil

10. Funtion of forest ecosystem
• Watershed Protection
• Atmospheric regulation
• Soil Erosion Control
• Wind Erosion Control

11. Desert Ecosystem
• High temperature, intense
sunlight and low water
• Flora and fauna are very
poorly developed and scarce
• Organisms are xeric adaptive
• Scarely populated

12. Types of desert
• Sand desert
• Stony desert
• Rock desert
• Plateau desert
• Mountain desert
• Cold desert

16. Plateau desert

17. Mountain desert

18. Cold desert

19. Features of desert ecosystem
• Rainfall
• Temperature
• Soil
• light
• Plants and animals are adapted to live in
extremities

20. Funtion of desert ecosystem
• Solar energy resource
• Mineral resource

21. Grassland Ecosystem
• Marginal rainfall
• Vegetation is dominated by grasses
• Unimproved wild-plant communities
• Densely populated

22. Types of Grassland Ecosystem
• Tropical grassland
• Temperate grassland
• Others

23. Features of grassland ecosystem
• Temperature
• Precipitation
• Humidity
• Topography
• Unadaptive plants and animals

24. Funtion of grassland ecosystem
• Grassland provide food
• Grasslands Are Breeding Areas
• Human habitat

25. Aquatic Ecosystem
• Low temperature and sunlight
• Soil and vegitation is submerged
• Flora and fauna had adapted
• Densely populated.

26. Types of Aquatic ecosystem
• Ocean
• Lotic
• Lentic
• Wetland

27. Features of aquatic ecosystem
• Light and temperature
• Current
• Chemistry
• Competitive organism

28. Funtion of Aquatic Ecosystem
• Recycles nutrients
• Purify water
• Resposible for proper rainfall
• Attenuate floods
• Recharge ground water
