Today in class we focused a lot on pyramids of energy. When we first walked into class we got a diagram which was very similar to the one on p.77 and p.78 in the Biology textbook or the one right on the blog.
<-- We talked about how in each tropic level 90% of the energy is lost therefore only 10% is passed on to the next level. We also learned that primary producers always make up the first trophic level, then other consumers take up every other level. On Wednesday we also talked about Biomass. Biomass: The amount of living tissue within a given trophic level. Typically the greatest Biomass is at the base of a pyramid.
If you want more practice on energy pyramids just go to p.20 in your Issues in Ecology packet. Again p.77-78 also have further explanations on energy pyramids.
To finish off the end of the day we received the oil spill video project rubric and chose our partners for the project, also decided which point of view we will be presenting our project in. We also formed groups and discussed/ worked on p.21 in out Issues of Ecology Packet.
Homework:
-Read 4.3 in textbook with double bubble map due friday. (template of double bubble map on moodle) "primary and secondary"
-10 images of oil spill due Tuesday, you and your partner must have 10 separate pictures!
Our next scribe is Josh
