David put a plant in a black box as shown. The box also had a black lid to cover the front. David only opened the box to add water to the plant. The plant stayed in the box for 10 days. When David took the plant out of the box on the tenth day, the plant was dead. Why did the plant dead only after ten days in the box?

Respuesta :

Answer:

the plant died because of lack of sunlight

Explanation:

A plant gets its food from the photosynthesis process, which combines CO₂ and H₂0 into carbohydrates, the two substances are in the box, but for this they need energy from sunlight.

           CO₂ + H₂O + Sunlight /chlorophyll → (CH₂0)ₙ + O₂

the extra oxygen is released into the atmosphere.

Therefore the plant died because of lack of sunlight
