Today we had a double block. In the First block we learnt about biotic potential and at the end of the block we got assigned a sheet with questions on lemmings. The second block we worked our ecosystem projects or did our homework.
Todays cless was pretty good. We learnt lots of new info. We learnt the 4 factors of biotic potential: birth capacity, capacity for survival, breeding frequency and length of reproductive life. We also learnt carrying capacity: max number of indivuduals of a species that can be supported at a time by an ecosystem; Law of min: nutrient in the least amount is the one that limits growth; Law of tolerance: organism can survive within a particular range of an abiotic factor. We also learnt density-depentant/independat factors. It was kind of boring first block but the second black was really good. We just worked on our projects.
These graphs are examples of carrying capacity and the law of tolerance.

good stuff, Sarah.
Next time, please give thoughts about the material (e.g. where it applies to real life, other questions it raises, etc).
