Examples of Symbiosis

Predator/Prey- A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.

 

Parasitism- Parasitism is a type of non mutual relationship between organisms of different species where one organism, the parasite(mosquito) , benefits at the expense of the other, the host(human). 

Mutualism- Mutualism is the way two organisms of different species biologically interact in a relationship in which each individual derives a fitness benefit (i.e., increased or improved reproductive output).

Commensalism- In ecology, commensalism is a class of relationship between two organisms where one organism benefits but the other is neutral (there is no harm or benefit).

Food Web Blog

bigelow.org

                     In the global environmental structure, a food web exists for life to continuously go on based on what they eat. As producers, trees and plants make up the base of the food web. They are then eaten by the primary consumers, which include deer, birds, rabbits, chipmunks, and insects. Those animals are subsequently eaten by the top of the chain: foxes, owls, and hawks.

Geological Period Blog

The Triassic period.     The Triassic period was the first part of the mesozoic era .It took place about 200 to 250 million years ago, with the weather back then being mostly dry and hot.The continents was still connected in one piece until the mid Triassic period where it broke off and began to separate into two pieces.Although there were dinosaurs during the triassic period, they did not become dominant until the Jurassic and cretaceus period.

Natural Selection Blog

Natural selection is the process in which certain traits become more or less common in an animal. Natural selection occurs when a random mutation or event happens and creates a trait that is advantageous, therefore increasing an organism's reproduction rates and providing it an oppourtunity to pass on the favorable trait. Natural selection is important because it is through this process that the phenotypes and genotypes continuously improve over time.

Cloning Blog

Do the benefits of human cloning outweigh the costs of human dignity?

 

No, the benefits of human cloning do not outweigh the costs of human dignity. Although there can be medical benefits found within cloning, one must take into consideration the individuality and uniqueness found in each person. With the cloning of a human being, the appreciation for for that indivudual for who they are would be shattered. In addition, clones can easily be used as a target for teasing against the original person, thus creating social barriers and generally worsening the overall atmosphere.
