Question: What is the ultimate energy source for 99% of life on Earth?

In most ecosystems, the ultimate source of all energy is the sun.

What does most of the energy for life on earth come from?

3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

What is the source of nearly all of Earth’s energy?

Nearly all of the earth’s energy comes from the sun. Some of this radiant energy is reflected by water droplets and dust particles in the atmosphere and bounced back into space or scattered throughout the atmosphere; some is absorbed by clouds or ozone.

Where does all the energy on Earth ultimately come from?

Although much of the energy we use in our everyday lives comes from local sources, ultimately the source of essentially all the energy that makes life on Earth possible comes from the sun.
