EVERYDAY SCIENCE

Detailed explanation-1: -Because green plants are the only living organisms capable of producing their own food, all other living organisms depend on them either directly or indirectly for survival. Green plants are the only living organisms that produce their own food.

Detailed explanation-2: -Photosynthesis is essential to all life on earth; both plants and animals depend on it. It is the only biological process that can capture energy that originates in outer space (sunlight) and convert it into chemical compounds (carbohydrates) that every organism uses to power its metabolism.

Detailed explanation-3: -All living organisms need energy to grow and reproduce, maintain their structures, and respond to their environments. Metabolism is the set of life-sustaining chemical processes that enables organisms transform the chemical energy stored in molecules into energy that can be used for cellular processes.

Detailed explanation-4: -Answer 3: Most organisms either directly or indirectly use energy from the sun to survive, but not all of them. Plants and some microbes use the energy from the sun to perform photosynthesis. In photosynthesis, light energy is used to combine CO2 in the air with water to make sugars and oxygen.
