Who has given 10% law?
Reymond Lindeman gave ten per cent of energy transfer law or Lindeman’s trophic efficiency rule in food chains. The 10 per cent energy is transferred from one trophic level to the next successive trophic level according to this rule.
What is the first step in energy flow through an ecosystem?
The flow of energy through living organisms in most ecosystems begins with photosynthesis. This process stores energy from sunlight in the chemical bonds of glucose. This energy transfers up the food chain as one organism eats another. For example, a grasshopper is a primary consumer that eats grass.
What is 10% law of energy?
The 10% Rule means that when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on.
