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).
Why is sun the ultimate source of energy on Earth?
The Sun is the Ultimate Source of Energy. Every morning the sun rises bringing light and heat to the earth and every evening it sets. … Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Animals eat plants and use that same chemical energy for all their activities.

What is the ultimate source of almost all energy driving ecological functions on Earth?
Ultimately sunlight is the key source of energy that supports almost all life and ecosystems. Sunlight is used by photoautotrophs to combine carbon dioxide and water into simple organic molecules through the metabolic process of photosynthesis. The fixed energy of plant biomass supports ecological food webs.
What is the main source of energy to all organisms in the earth?
Living things need energy to grow breathe reproduce and move. Energy cannot be created from nothing so it must be transferred through the ecosystem. The primary source of energy for almost every ecosystem on Earth is the sun.

What are the two ultimate sources of energy for the Earth system?
The earth is a vast complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere which generates geothermal heat) and an external source (the solar radiation received from the Sun) the vast majority of the energy in the earth system comes from the Sun.
Does the earth produce energy?
Most of the energy in the Earth system comes from just a few sources: solar energy gravity radioactive decay and the rotation of the Earth.
What is the ultimate source of energy that drives geological activity?
Much of Earth’s energy comes from the Sun. Nearly all life on Earth depends on solar energy since plants use sunlight to make food through the process of photosynthesis. Photosynthesis was the process that fed plants and animals which in turn over the course of millions of years became fossil fuels.
