LIFE SCIENCE

Detailed explanation-1: -Photosynthesis is the process by which green plants produce carbohydrates using carbon dioxide, and water in the presence of sunlight. This process can be termed as the most important life process in the ecosystem as it enables the conversion of light energy of the sun to chemical energy in the form of carbohydrates.

Detailed explanation-2: -It is the source of energy and food for all organisms. It releases oxygen into the environment which is utilised by organisms.

Detailed explanation-3: -The process by which plants utilize sunlight (absorbed by chlorophyll) to make food (that we need for our lives) and oxygen (that we need to breathe) from carbon dioxide (CO2) and water is called Photosynthesis. In addition, past photosynthesis provides the fossil fuels needed to power the industry and automobiles etc.

Detailed explanation-4: -In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
