答案

两篇
Plants need light to grow.In fact a plant cannot grow in the absence of light.Plants majorly act as the producers in the economy therefore,they produce food not only for their own use but also for the use of men.Light is very necessary for the plants because plants take energy from the sunlight and use that energy in making food.Food is in the form of glucose and it is prepared by plants by using carbon dioxide and water in the presence of sunlight.The reaction is as follows:
Carbon dioxide + Water + Light energy ------> Glucose + Oxygen
Therefore,light is very important for the plants for making glucose and to grow.
All living things need light and heat from the sun to live.Plants need light and heat to grow.They use the light from the sun to make food.We cannot make our own food,but plants can.All the food we eat comes from plants in a food chain which starts with the sun.For example,animals need sunlight,too.Just like us,their comes from a food chain which begins with the sun and the plants.
所有生物都要依靠太阳的光和热而生存.植物需要光和热才能生长,它们接受阳光制造食物.我们无法自行制造食物,但植物可以.我们所吃的所有食物都来自食物链中的植物,而其源头则是太阳.动物也需要阳光.就象我们一样,动物也是食物链中的一环,而食物链正是起源于植物和太阳.
