| Video Discription | Structure & Composition of Ecosystem The composition of the biological community including species numbers, biomass, life history and distribution in space etc. The quantity and distribution of non-living materials, such as nutrients, water etc., and The range or gradient of conditions of existence, such as temperature, light etc. From structural point of view all ecosystems consist of following two basic components: Biotic (living)components Abiotic (non-living) components Producers(Autotrophs) These are those organisms which prepare their own food by using solar energy, chlorophyll, inorganic nutrients and water (Photosynthesis) e.g, plants, some photosynthetic bacteria, algae etc. Some Exmamples of producers in different ecosystems are: Algae and other hydrophytes of in Aquatic ecosystem, Grasses in Grassland ecosystem, Trees & Shrubs of the forests etc. Chemosynthetic bacteria and carotenoid bearing purple bacteria that also assimilate CO2 with the energy of sunlight but only in the presence of organic compounds also belong to this category. Consumers Animals which obtain their food from producers. These are : Primary Consumers Secondary Consumers Tertiary consumers Quaternary Consumers Decomposers They are tiny organisms includes bacteria and fungi, which turn organic compounds of dead plants and animals into inorganic materials. Inorganic Components: The inorganic components of an ecosystem are carbon dioxide, water, nitrogen, calcium, and phosphate. All of these are involved in matter cycles (biogeochemical cycles). Organic Components: The organic components of an ecosystem are proteins, carbohydrates; lipids and amino acids, The climate, temperature, light, soil etc., are other abiotic components of the eco-system.
