Generally speaking, plants are able to manufacture their own food,
by using substances in the environment through the process
which is known as photosynthesis.
They can grow very well if they have enough sunshine, rainfall and fertilizer.

but enjoy cruelly killing others.

Life could not go on if there were no plants.
This is because plants can make food from air, water and sunlight.
Animals and man cannot make food from air,water and sunlight.
Animals get their food by eating plants and other animals.
Man gets his food by eating plants and animals,too.
