Some people say that plants make their own food from the Sun through the process of photosynthesis. Based on the law of conservation of energy, is this description accurate? Explain your response.

Explanation : Yes , based on law of conservation , the description is accurate because plant convert light energy into mechanical energy. 

Plants are called autotrophs because they can use energy from light to synthesize, or make, their own food source.

We mean that plants make molecules (such as sugars) that carry energy obtained through other means. Plants cannot use sunlight directly to power their biochemical reactions, so they must turn sunlight energy into other forms of energy they can use, hence the processes of photosynthesis and respiration. 

Photosynthesis is a food-making process that occurs in green plants. It is the chief function of leaves. The word photosynthesis means putting together with light. Green plants use energy from light to combine carbon dioxide and water to make sugar and other chemical compounds.
