Answer: All the statements are true except that they release carbon dioxide in the atmosphere
Step-by-step explanation:
The autotrophs are the group of organisms that make their own food by trapping the sunlight from the sun.
They make food by the help of carbon dioxide and water. This process is important to start all the food chain.
By the help of this process glucose is made and oxygen is released into the atmosphere.
They are very important for the living forms on earth as they only have the ability to make food.
