Most animals have little connection with animals of a different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership which is good for both of them. You may have noticed some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites(寄生虫)on the sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So, although they can manage without each other, they do better together.
Sometimes an animal has a plant partner. The partnership develops until the two partners cannot manage without each other. This is so in corals(珊瑚)of the sea. In their skins they have tiny plants which act as "dustmen" , taking some of the waste products from the corals and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are even prevented from receiving light so that they can not live normally, the corals will die.
What does the second paragraph mainly discuss?
选项
A、some plants depend on each other for food
B、Some animals and plants develop their relationship easily
