Question

energy flow is necessary to maintain the cycle of life.However as we move upwardsin trophic levels ,number of species decreases.Use energy flow models to describe this scenario​

i dont no your question answer

Answer 2

Answer:

Energy flow is the flow of energy through living things within an ecosystem.[1] All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain.[2][3] Each of the levels within the food chain is a trophic level.[1] In order to more efficiently show the quantity of organisms at each trophic level, these food chains are then organized into trophic pyramids.[1] The arrows in the food chain show that the energy flow is unidirectional, the head of the arrows show the direction energy is moving in, and that energy is lost as heat at each step along the way.[2][3]

The unidirectional flow of energy and the successive loss of energy as it travels up the food web are patterns in energy flow that are governed by Thermodynamics, which is the concept of energy exchange between systems.[4] [5] Trophic dynamics relates to Thermodynamics because it deals with the transfer and transformation of energy (originating externally from the sun via solar radiation) to and among organisms.[1]
