| Video Discription | The structure of an ecosystem is basically a description of the organisms and physical features of environment including the amount and distribution of nutrients in a particular habitat. It also provides information regarding the range of climatic conditions prevailing in the area. The structure of an ecosystem can be split into two main components, namely: Biotic Components Abiotic Components The biotic and abiotic components are interrelated in an ecosystem. It is an open system where the energy and components can flow throughout the boundaries. Biotic components refer to all life in an ecosystem. Based on nutrition, biotic components can be categorised into autotrophs, heterotrophs and saprotrophs (or decomposers). Producers include all autotrophs such as plants. They are called autotrophs as they can produce food through the process of photosynthesis. Consequently, all other organisms higher up on the food chain rely on producers for food. Consumers or heterotrophs are organisms that depend on other organisms for food. Consumers are further classified into primary consumers, secondary consumers and tertiary consumers.Primary consumers are always herbivores that they rely on producers for food. Secondary consumers depend on primary consumers for energy. They can either be a carnivore or an omnivore. Tertiary consumers are organisms that depend on secondary consumers for food. Tertiary consumers can also be an omnivore. Quaternary consumers are present in some food chains. These organisms at the top of a food chain as they have no natural predatorsprey on tertiary consumers for energy. Furthermore, they are usually Decomposers include saprophytes such as fungi and bacteria. They directly thrive on the dead and decaying organic matter. Decomposers are essential for the ecosystem as they help in recycling nutrients to be reused by plants. The functions of the ecosystem are as follows: It regulates the essential ecological processes, supports life systems and renders stability. It is also responsible for the cycling of nutrients between biotic and abiotic components. It maintains a balance among the various trophic levels in the ecosystem. It cycles the minerals through the biosphere. The abiotic components help in the synthesis of organic components that involves the exchange of energy. 0:00 Structure of Ecosystem 3:11 Producers 4:00 Consumers 5:28 Decomposers 6:13 Abiotic Components 7:22 Functions of Ecosystem #Ecosystem #StructureOfEcosystem #FunctionsOfEcosystem #Producers #Consumers #Decomposers #Abiotic #Biotic #Ecology #FoodChain #FoodCycle #NutrientsFlow #NutrientsCycle #SaadRahoojo #LearningAndSharing #CSS #UPSC #UniversityOfSindh #Geography h06q_V55FkM |
