- started our review sessions preparing us for finals
- reviewed E and Matter Exchange in the Biosphere
- did practice test pertaining to the above bullet
- started into reviewing Ecosystems and Population Change
Thoughts and Opinions:
- it was good to start review in class considering lots of people probably hadn't started until then
- the first law of dynamics kind of makes me question it, because isn't there the exception of the sun? (unless you get really deep into it and look at the physics part of it all)
- if you took any part of an ecosystem away, the whole thing would have to shift and adapt to maintain a dynamic equilibrium
Above and Beyond:
^ A diagram of how the greenhouse effect works.
- Question: What is an agal bloom?
Answer: a rapid increase or accumulation in the population of algae in an aquatic system.
- An example of nitrogen fixing bacteria: Nitrogen fixation is utilized by numerous prokaryotes, including bacteria, actinobacteria, and certain types of anaerobic bacteria. Microorganisms that fix nitrogen are called diazotrophs. Some higher plants, and some animals (termites), have formed associations (symbiosises) with diazotrophs.
