Autotrophs on land get their energy indirectly from the sun while those in the deep ocean get theirs from chemicals.
Autotrophs on land get their energy from carbohydrates synthesized via photosynthesis.
Photosynthesis is a process that converts radiant energy from the sun to chemical energy locked in carbohydrates. These carbohydrates are then broken down during respiration in order to release the locked energy.
Autotrophs in the deep ocean lack access to sunlight and thus, cannot utilize radiant energy from the sun. Instead, they make their carbohydrates by making use of energy from chemicals like hydrogen sulfide and methane in a process called chemosynthesis.
