<span>Basically, the body needs to know what it is defending against. Your body can still (usually) fight off infection, even without an immunization, but it takes longer. Basically, your body creates cells with a receptor for a specific disease. When this cell finds the disease it is programmed for, it will send out signals to the "killer" cells to come and kill it. If your body doesn't have the "seeker" cells, it can't fight off the infection until it does. The opposite end are autoimmune diseases, where your immune system starts attacking itself.

In any food chain, the percentage of energy passed from one level to another usually reduced by a factor of 10%.
In the food chain given in the question, we are told that the rabbit ate grass and the hawk ate the rabbit.
The grass carried out photosynthesis and obtained 100% energy from the sun. When the rabbit ate the grass, he obtained 10% of the energy from the grass, thus, the quantity of energy it gained from eating the grass is 10%, that is, 100/10 = 10%.
When the hawk ate the rabbit, it was only able to get 10% of the energy in the rabbit, thus, the quantity of the energy it gained is 1%, that is 10/10 = 1%.
Therefore, 1% of the energy stored by the grass is passed on to the hawk.
