Answer:
“Stromatolites are pervasive in the fossil record and are some of our earliest examples of life on Earth,” he says. “The microbial mats that created them were predominantly made up of cyanobacteria, which used photosynthesis – like plants do – to turn sunlight into energy while producing so much oxygen over time they changed the early Earth’s atmosphere to make it habitable for complex life.

Answer:
Cellular Respiration
Explanation:
Metabolism is the sum of chemical reactions taking place in the living organisms. Cellular respiration is one such metabolic process. Cellular respiration takes place in in the all organisms in which respiratory substrate such as glucose is oxidised completely in presence of oxygen to produce carbon dioxide, water and energy (ATP). Cellular respiration begins in cytoplasm and completes in the mitochondria of the cell. The energy is used to do work.
The oxidation reaction is given below:
C₆H₁₂O₆+ 6O₂ → 6CO₂+ 6H₂O + Energy
