Today in class we started off by talking about the upcoming project involving the pictures. Mr. Paek will assign that sometime next week. Also make sure you are logged into blogger.
Next we went over the different kinds of consumers. First you have Primary consumers, they feed directly off of producers. They can also be called herbivores. next you have secondary consumers they feed off of the primary consumers. after that you have Tertiary consumers they feed off of secondary consumers. The last type of consumer is quatemary consumers and you guessed it they feed off of tertiary consumers.
We also went over what is called the pyramid of energy. The pyramid of energy is another way to show the way energy passes through different organisms. on the bottom is producers then primary consumers, then secondary consumers so on and so forth ending with quatemary consumers. Mr. peak explained that when energy passed to another level of the pyramid it losses 90% of the energy. so producers have a 100% energy but when a primary consumer eats a producer it only gets 10 % percent of that energy. it keep decreasing by 90% all the way down so it goes 100% 10% 1% .1% and .01%. there are two other pyramids called number pyramids and biomass pyramids. number pyramids show the total number of organism in each level. Biomass pyramids show the total number of mass in each level of the pyramid.
For the end of class we worked on pages 15,16,19 and 20 in the pink ecology packets
Homework: 15, 16, 19, 20(whatever you dint finish in class). Also you can do page 17 in the pink ecology packet for extra credit
