PRESENTATION OUTLINE
Ecosystems are composed of organisms interacting with each other and with their environment such that energy is exchanged and system-level processes, such as the cycling of elements,

Ecosystems include living organisms, the dead organic matter produced by them, the abiotic environment within which the organisms live and exchange elements (soils, water, atmosphere), and the interactions between these components. Ecosystems embody the concept that living organisms continually interact with each other and with the environment to produce complex systems with emergent properties, such that "the whole is greater than the sum of its parts" and "everything is connected".

There are two components: ABIOTIC AND BIOTIC COMPONENTS ABIOTIC COMPONENTS: Sunlight Temperature Precipitation Water or Moisture Soil or water chemistry BIOTIC COMPONENTS: Primary Producers Herbivores Carnivores Omnivores

OTHER ABIOTIC COMPONENTS Abiotic components are such physical and chemical factors of an ecosystem as light, temperature, atmosphere gases(nitrogen, oxygen, carbon dioxide are the most important), water, wind, soil. These specific abiotic factors represent the geological, geographical, hydrological and climatological features of a particular ecosystem. Separately:

Biotic Components include the following: Autotrophs produce their own organic nutrients for themselves and other members of the community; therefore, they are called the producers. There are basically two kinds of autotrophs, "chemoautotrophs and photoautogrophs. " Chemautotrophs are bacteria that obtain energy by oxidizing inorganic compounds such as ammonia, nitrites, and sulfides , and they use this energy to synthesize carbohydrates. Photoautotrophs are photosynthesizers such as algae and green plants that produce most of the organic nutrients for the biosphere.
