Which statement is an example of mutualism?
O A koala eats eucalyptus leaves, and it is unharmed by the poison in the leaves.
O A deer tick feeds on the blood of a deer, and the deer loses blood and nutrients.
A plover bird feeds on food stuck in a crocodile's teeth, and the crocodile gets its teeth cleaned in the process.
O A hookworm feeds on the small intestine of a dog, causing the dog to lose weight and become weak.
The bird and crocodile have the best example of mutualism because both animals benefit from the situation; the bird gets food from the crocodile's teeth and the crocodile gets a free mouth cleaning.
