Food Synthesis in Living Organisms

Autotrophism is the ability of living organisms to produce their own food. Green plants synthesize their food through the process of photosynthesis, using carbon dioxide, water, and sunlight energy.

Humans obtain their food from both plants and animals. They have the role of growing plants and rearing animals to meet their own requirements of food.

Animals cannot synthesize their own food because they lack the necessary enzymes and organelles. They obtain their nutrients by consuming other organisms, either plants or other animals.
