How the plants eat...
Plants need sunlight and water to make their own food.
You can do an experiment to test if this is true. Place a bucket over a patch
of green grass. After a few days, lift the bucket.
You will see that the grass is not as green anymore.
If you leave the bucket in place for a week, the grass will become very dull.
This happens because the grass cannot make food in the dark. Remove the bucket.
In a few days, the grass will start turning green again.
What is the main idea of
this passage?
