Productivity In Ecosystem Biology Diagrams The total amount of biological productivity in a region or ecosystem is called the gross primary productivity. A certain amount of organic material is used to sustain the life of producers (or autotrophs ) in a food chain , and what remains is the net primary productivity, which can be used by consumers (or heterotrophs , which are made up of
Primary productivity forms the basis of all food chains and food webs of the ecosystem. Without the primary productivity at the base, no food chain can be established as the higher organisms are "incapable" of utilizing the inorganic molecules as such (hence called non-assimilable inorganic compounds). This implies the importance of primary Primary productivity is a fundamental process that sustains life and maintains ecological balance. Its importance can be observed in several key aspects: Energy Flow: Primary productivity forms the basis of food chains and energy transfer in ecosystems, supporting the survival and growth of organisms at higher trophic levels.

Primary productivity is vital for the health of ecosystems for several reasons: Energy Source: It provides primary producers with the essential energy that fuels all food chains and webs. Biodiversity Support: Higher productivity typically leads to greater diversity in plant and animal species within an ecosystem.
According to Odum there are three types of productivities - primary productivity, secondary productivity and community productivity. Type # 1. Primary Productivity: Trophic levels are made on the basis of steps found in the food chain. There are usually around 4-5 trophic levels in a food chain and energy flows in only one direction in A food chain is a linear sequence of organisms where each living thing depends on the one below it as a food source. It shows how energy and nutrients are. Search. or we can assume that only 10% of the net primary productivity of producers ends up as herbivores and so on to the next trophic level. Net primary productivity is what is left over after the primary producer has used the energy it needs for respiration. This is the portion that is available to be consumed by the primary consumers and passed up the food chain. In terrestrial ecosystems, primary productivity is highest in warm, wet places with plenty of sunlight, like tropical
