mystery marine food chain

this week in science #13

                                                    This is a picture of my spider in its habitat


      If I were to add more spiders to my spider habitat they would be producing 5x the carbon dioxide needed. This also means that the plants and vegetation in this habitat would have to also produce enough oxygen and glucose to allow the spiders to live in this environment. The plants and vegetation would have to photosynthesize even more to produce food for themselves because they're producing extra glucose and oxygen for the spiders. 

This week in science #12

       This week in science we went online and played a few games to help us with food webs and chains. The games showed me how the chains and food webs help establish the animal's ecosystems. We also later filled out packets and figured out what producers, consumers, and decomposers do for their ecosystems. Later in the week we created booklets about the spiders we are studying, Cellar Spiders. We included facts about their ecosystems and background research.


        I learned that the difference between food webs and food chains is that a food chain is a single line of organisms in which each is preceded by something that it consumes, and followed by something that consumes it. A food web branches out in every direction pointing to every organism that it consumes and what consumes it. I also learned that decomposer can consume both producers and consumers and is the only one to do so. Also that most consumers are carnivores, and most producers are herbivores. and that most all plants are producers. We got as far as learning about energy pyramids and symbiotic relationships.
