Glucose + Oxygen
Water, oxygen, sunlight and minerals.
Oxygen comes from the process of photosynthesis. This is when plants take sunlight, water and carbon dioxide to make sugar and form oxygen wich goes in to the air for us to breathe.
Sort of, it's plants that recycle carbon dioxide back into oxygen and they need sunlight to do this.
Oxygen is produced by living plants. Plants use Carbon Dioxide, Water and Sunlight to make Sugars and Oxygen. As sunlight is required and there is more of this in summer, more oxygen is produced in summer than winter.
Plants use carbon dioxide and water along with sunlight during photosynthesis to produce glucose (food) and oxygen.
carbondioxide+sunlight+water=oxygen+glucose
The process through which plants receive sunlight, water, and carbon dioxide and produce oxygen and sugars (glucose) is called photosynthesis.
Because the Sugar is the plant's food - plants make their own food by trapping the energy in Sunlight.
because plants make oxygen with the help of sunlight and sunlight is present between 6 am to 6pm. so the oxygen level is high.
Sunlight Carbon dioxide Water Plants need air while making food but not oxygen. Plants only need oxygen at night.
Green plants that make their own food using sunlight are called autotrophs. This process is known as photosynthesis, where plants convert sunlight, water, and carbon dioxide into glucose and oxygen.
