Many autotrophs make food through the
process of photosynthesis, in which light energy from the sun is changed
to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.
We can tell from their structure that fatty acids are a good source of energy because of their large number of carbon-hydrogen and carbon-carbon bonds that they contain. Most fatty acids have straight chain compounds with an even number of carbon.
It controls all the involuntary actions like digestion and beating of our heart
