Animal kingdom

some of the relationships in the nature are:




  1. Mutualistic: is the way two organisms biologically interact where each individual derives a fitness benefit. Similar interactions within a species are known as co-operation. An example of this relationship is: the relationship between sea anemones and anemone fish: the anemones provide the fish with protection from predators (which cannot tolerate the stings of the anemone's tentacles) and the fish defend the anemones against butterfly fish which eat anemones.  
  2. Commensal: is a class of relationship between two organisms where one organism benefits but the other is neutral (there is no harm or benefit). Example: Orchids and mosses are plants that can have a commensal relationship with trees. The plants grow on the trunks or branches of trees. They get the light they need as well as nutrients that run down along the tree. As long as these plants do not grow too heavy, the tree is not affected.
  3. Parasitic: is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host.A few examples of parasites are tapeworms, fleas, and barnacles. Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows, pigs, and humans.


    What is symbiosis??!!
    Symbiosis is a situation in which 2 different organisms live together in close association. Just living in the same place is not enough. By "close association" biologists mean that if they are separated, one (or both!) of these organisms will probably die. 


    How can relate symbiosis  relate to friendship? 
    In friendship when you have a friend  you want to be with him/her just to have fun or do stuff together. symbiosis is when 2 organism live together in close association and in the case of a friend you share time with him/her so it can say you have a symbiotic relationship
