THE DANGER OF TICKS

Parasitism is when one organism, usually physically smaller of the two (the parasite) benefits and the other (the host) is harmed. The example that we'll be talking about today, is probably the most common type, the tick. A tick is a parasitic arachnid that attaches itself to the skin of a terrestrial vertebrate from which it sucks blood, leaving the host sated. The tick can leave some serious diseases behind, including tularemia and Lyme disease. One of the ticks favorite meals is the dog. Everybody should know what a dog is, the tick is difficult to find in dogs. The dogs have hair all over its body sometimes long, and sometimes short, that why its perfect for ticks. The role of the tick is to land on the host (dog) and it attaches itself anywhere on the dog. Most of the time on the body of the animal. Then the tick can live there for days, weeks, or months until it dies or someone or something takes it off. When the tick is there is drinks the dog's blood or even worse can give the dog diseases. If its severe the dog can get really sick or die. The advantages of being the tick in this situation are great, they have an infinite food supply and a home to live. The disadvantages of the tick is they have plenty of predators to kill them. Examples are reptiles, birds, and amphibians. Another disadvantage is if the owner of the dog looks out for the dog the tick can be killed in a short amount of time of being on the host. The advantage of having a tick is nothing, in our point of view. but say in the animals the eat ticks, its an advantage for them.. The disadvantage of having a tick is they can cause serious diseases and they can take large amounts of blood from you.
