Blog 10



The contamination of one animal in a food web can have a large effect on the entire food web itself let me explain why a food web has two basic animal species producers and predators the side effects of one being contaminated is that it sets off a chain reaction let me use a very basic example EX. someone poisons grass then a rabbit eats it and dies then a predator like a fox comes and eats that then it to dies and the rabbit population could be eating that same type of grass and dying then due to the chain effects some predators die and the population can go to ways the rabbit population can ether explode with not enough predators or the predators will outnumber the rabbits and can possibly extinct the species.

week 12 blog



Based on my dissections that I have preformed in class on species like a worn, starfish, and flower
I can say that they are completely different not only in the way that they live but also in there body structures like the starfish to the worm. The worm has a elongated digestive system where the starfish is well obviously not only in a star shape but is more centered than that of a worm also the starfish has a strong exoskeleton where the worm does not and thusly is easier to cut open but that also makes it more easier to damage while doing this important and necessary step. Like when you cut the worm you have to be gentle and light while cutting or you will destroy its entire digestive track.
