* Animals depend upon each other to survive * Three types of predator-prey relationships * Hunters and hunted * Relationships where both species benefit * Relationships where one animal benefits and the other is harmed

* Animals that hunt for their food are called predators. * Animals that are being hunted are the prey. * Predators kill their prey for food in order to survive.

* New construction in the everglades reduced the habitat of the apple snail. * cause: the construction reduced the population of the apple snail. * Effect: the snail kite was put on the endangered species list.

* Some predators are very fast and simply chase their victims. * Some prey have adapted to protect themselves. * Some prey survive as a species because they have so many babies.

* Run swim or fly fast to catch your prey on the run. * Run swim or fly for a long time, a cheetah can run up to 60 mph but can maintain its speed for only a few hundred yards * Be patient, the polar bear waits by breaks in the ice

* Scavengers are animals that eat the bodies of dead animals. * The spotted hyena of Africa is both a scavenger and predator. * Once a hyena makes a kill or finds a dead animal other hyenas join in the feast.

* The partner ship between the clown fish and the anemone is a example of mutualism. * The clown fish is a very slow swimmer so it hides in the sea anemone and attracts predators. * When a clown fish attracts a predator the sea anemone stings it the clown fish is immune to this sting then the sea anemone swallow’s the predator and the clown fish gets left overs.

* The remora and a shark is a example of one sided relationship. * The remora have suction disks one their head to attach their self to a shark. * The remora gets left overs from the shark meal.

Deer ticks are parasites that feed on the blood of birds and mammals. Some deer ticks carry Lyme disease, a serious bacterial infection. In the 1990s scientists developed a vaccine for Lyme Disease.

* In some parts of the western states humans are bike riding camping and hiking. * It does not happen often but sometimes mountain lions attack. * Only a dozen humans have been killed by a mountain lion in the past 100 years.

* Animals that hunt are and animals that are being hunted are the.

* Cause: if the apple snails habitat is in reconstruction. * Effect: less food for the snail kite to eat.

* Why are the clown fish immune to sting of the sea anemone but others are not.

* Why doesn't a big fish eat the wrasse when it comes in its mouth.
