Symbiotic Relationships

By: Jazmine Mohamed


Mutualism is a symbiotic relationship in which both organisms benefit. 1. One example of mutualism is the zebra and the oxpecker. Oxpeckers land on zebras and eat parasites that are on the zebra's skin. 2. Another example of mutualism is a bee collecting nectar from flowers. The bee gets the food that it needs while pollinating the flowers. 3. Another example of mutualism is the bacteria and the human. The bacteria in the intestines eat and digest the food that the humans can't. 4. Another example is a plant and a human. Plants let out oxygen which humans need, and humans let out carbon dioxide which plants need. 5. Another example is white blood cells and a human. The white blood cells get what they need by fighting invaders in a human.


Commensalism is a symbiotic relationship in which one organism benefits and the other one isn't affected. 1. Remora sharks and other sea animals is an example of commensalism. The Remora shark clings on another sea animal and takes a ride to where it needs to be. The animal it rides on doesn't get affected but the remora shark benefits. 2. Another example is when a snail dies the hermit crab can use the snail's shell. The snail is dead so nothing happens to it but the hermit crab gets a new shell. 3. Another example is a cattle egret and livestock. The livestock grazes on grass and stirs up insects. The cattle egret follows the cattle and eats those insects. Nothing happens to the cattle but the cattle egret easily gets food. 4. Another example is a tigers and a golden jackal. The golden jackal follows the tiger so it can get some of the tiger's food. The tiger isn't affected but the golden jackal benefits. 5. Another example is a barnacle and a whale. The barnacle benefits because it gets more food when the whale moves and nothing happens to the whale.


Parasitism is a symbiotic relationship where one organism benefits and the other one is harmed. 1. An example is head lice and a human. The louse sucks the blood out of a human to lay eggs and the human gets affected because they start to itch. 2. Another example of parasitism is hookworms. Hookworms live in the small intestines and suck your blood. This can lead to anemia. 3. Another example is a mosquito bite. The mosquito sucks your blood and the bite causes you to itch. 4. The flu virus and a human is an example of parasitism. If you have the virus then you will feel really bad and throw up and lots of other terrible things. 5. Another example is a ladybug and a bird. The bird eats the ladybug which tastes really bad. The bird never eats any ladybugs again. The bird gets harmed but the ladybugs benefit because the bird won’t ever eat anymore ladybugs.
