Energy is imperative for durability, growth and many other factors for the living systems.
The two chief sources of energy that power subsistence systems are photosynthesis and chemosynthesis.
- Photosynthesis is a method by which plants apprehends the sun energy and carbon dioxide from the surrounding atmosphere and transform them into biochemical energy including oxygen and glucose.
- The food made by plants are consumed by the herbivores and the food web gets interlinked making it essential for survival.
- Chemosynthesis involves the synthesis of glucose or simple sugar molecules by bacteria or prokaryotes by utilising the chemical as the source of energy.
- An example of chemosynthesis is methanogenic bacteria that produce food and methane as a byproduct.
