Energy Pyramid & The Food Chain 2/19/17

Summary:
The food chain is the process in which animals go from the producer to primary consumer, herbivore consumer, omnivore consumer, and carnivore consumer. The food chain is like a cheerleading pyramid. The lowest get has more work holding up the people while the people at the top get less work by just balancing. And if on person missteps of is absent the the pyramid just falls apart. Its just like the food chain because the food chain at the bottom is the maintainment of the whole pyramid and if does its function wrong or if the producer starts to decrease it affects the whole pyramid by decreasing the insect population because the insects are running out of producers to eat. And if the grasshoppers decrease the the mouse population will lower because the insects are dying out causing the owl to start decreasing making the whole pyramid collapse and everything goes extinct.

S&EP:SP3: Planning And Carrying Out Investigations
We did gizmos and experiments and investigated what would happen if we increased the number of producers or consumers. Or what happened if we decreased the number.We also played a game where each table was given a cycle either carbon cycle or nitrogen cycle and you would have to roll a dice to see where you would end up like for the carbon cycle i went from atmosphere to surface water. And then once we got all the facts that the game gave us we would be paired up with another table that was he opposite cycle and have 8 minutes to explain our cycle to them and then after we had a quiz on both cycles based on what the table groups and game taught us.

XCC: Cause & Effect
Like I said the food chain is very fragile because if one animal or plant starts to die off everything goes down. And in this case the animals and plants all depend on one another so there no "every plant or animal for themselves!". They are all in it together. Either the plant and animals are in a stable chain or they are slowly dying off. Lets say the food chain is grass gets eaten by rabbits and the rabbits get eaten by foxes and the foxes get eaten by hawks. So if the grass population starts to decrease the the rabbits will decrease due to the lack of grass causing the foxes to die with lack of rabbits and so on.
