The sun is a source of energy but we cant use it for ourselves other than staying warm. the main source of energy for most living things are nucleic acids, they send chemical reactions to the body that make us who we are -Edited by Jordan R.
i believe it was the sun

Only plants can be autotrophic (using light or chemical energy as their energy source). Animals are all heterotrophic.
Solar Energy. Without it, all living things will die. With solar energy, we have vegetation, for animals to survive on. And the humans have both animals and plants to survive on therefore all living things need the Sunlight/Solar Energy to live. It is the source of energy for all producers.
Carbohydrates are used as an energy source for many animals and plants. Examples: potato makes starch to store energy and animals eat them to gain the energy they need. Also sugars, which are monomers, are used by the plants as energy source by photosynthesis. Second example would be that insects use a carbohydrate called chitin which is used to build their exoskeleton.
The sun.Without the sun life on earth would soon stop because all available carbon (the basis of all life forms on Earth) would be used up.A few ecosystems get their energy partially or entirely from geothermal sources. The original source of this energy is radioactive decay heat from isotopes in the crust, mantle, and core.Both the sun and earth were formed from matter ejected and/or compressed by supernova explosions. So the original source for both the energy from the sun and from radioactive decay heat was supernovas.Ultimately the original source of all energy was the Big Bang.
Storage of food in plants. As starch is insoluble and compact, it is the most ideal form for storage in plants. For animals, starch is a source of carbohydrate. Therefore source of energy.
The sun its so simple
The energy source is the sun. Plants use solar energy to produce the foods they need for growth. Animals feed on the plants or feed on animals that eat plants.
Plants,animals,water
it is not renewable

because plants get their energy from it and everything else gets their energy from plants
ATP is an immediate source of energy for animals and all living things.
Only plants can be autotrophic (using light or chemical energy as their energy source). Animals are all heterotrophic.
Only as an energy source, it requires amino acids for animals to make proteins.
ecosystemIn most food webs the Sun is the ultimate source of energy.
