What is the ultimate source of energy in milk explain?
The energy in milk comes from its protein, carbohydrate and fat content, with the exception of skim milk that has virtually no fat. The energy content of some milk varieties is shown in the Nutrient Content Tables. Food provides energy to the body in the form of calories (kcal).
What is the ultimate source of energy of producers?
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

What is the main source of solar energy?
Answer: The main source of solar energy is the SUN. Energy is produced by nuclear fusion in the core region through a series of steps called the p–p (proton–proton) chain in the surface of the sun; this process converts hydrogen into helium and massive light and heat energies.
What is the ultimate source of energy in an ecosystem Class 9?
The ultimate source of all ecosystems is the sun or the solar radiation as the energy enters through the process of photosynthesis.
What is the ultimate source of energy of the biosphere?
The primary source of energy for ecosystem processes is photosynthesis. Directly or indirectly, photosynthesis provides the energy for all forms of life in the biosphere. Photosynthesis utilizes energy from the sun to reduce CO2 into high energy organic compounds.
