Food. Extras page 4 of 4

Life needs food. It comes in varieties. If anything needs understanding about life , it is food. In some way food could be considered to have occurred before life.
Take trees and plants that sort of eat the carbon that is in the air using photosynthesis to form themselves and their fruits that are in turn eaten by animals. Those animals are then eaten by other animals and so on.

How is it that life has been able to sustain itself on food for 500 million years and is still doing so today. How does that food keep coming and coming. There isn’t as far as we know , anything coming from outer space apart from sunlight , and so the food that exists must be sort of available again itself after whatever has eaten it in the past. Problem with that though is that food eaten by an animal is thought to be converted to a sort of energy to give the thinking and ability to move the body. But there is of course the fact that not all of the food eaten is converted into energy and so most of it goes back into the soil. Only a tiny bit of that food is needed to provide energy , after all , an atomic bomb that splits single atoms , unleashes an immense amount of energy.
