TWIS #12

This is my spider log book that I
created to keep information on my spider. 

              This week in science was a very interesting week because we had to learn about symbiotic relationships,energy pyramids, and food chains. A food chain shows each how each living thing gets its food. A energy pyramid is different levels that represents groups of organisms.A symbiotic relationship is mainly from the root symbiosis which is an interaction process between two or more biological species. However it is split up into different categories which is mutualism, parasitism and commensalism. Mutalism is the relationship between two species of organisms in which both benefit from the associate. Commensalism is the living together of two organisms in a relationship that is beneficial to one and had no effect on the other. Parasitism is a symbiotic relationshipin which organism benefits and the other doesn't. We also watched brain pop videos about them and test our knowledge by doing worksheets. 

            This week in science I did a lot of things such as creating ,my spider log book and  writing down what I found interesting in the tank and what had change through out the ecosystem, the days I  wasn't able to check it.  We also played a game on David's blog about symbiotic relationship and how one organism could affect the  food chain and how  the ecosystem works.
