Living things need air, water, and food to survive. Air is essential for respiration, which is the process of taking in oxygen and releasing carbon dioxide. Without air, living organisms would not be able to breathe and obtain the necessary oxygen for their metabolic processes. Therefore, air is a vital requirement for the survival of living beings.

Plants require water, air, and sunlight to live. Sunlight is essential for the process of photosynthesis, where plants convert sunlight into energy to fuel their growth and survival. Without sunlight, plants would not be able to produce food and would eventually die. Therefore, sunlight is a crucial factor for the survival of plants.

It is primarily used for playing sports and does not provide an accurate measurement of length.
