Hi folks,
Well, a depressing class this week. We've been talking about ecology and ecosystems and I wanted to tie in that information with some of the threats that are facing them at the moment. We talked about deforestation, desertification, non-native species, over-harvesting and pollution. Next week we will cover the biggie, climate change. We also took a look at all the "services" the environment provides for us (46 trillion dollars worth!).
For homework next week, I'd like you to tie 10 of the concepts we've been working with in biology this year to the topic of Genetically Modified Organisms (GMO's) and give me at least one example of how GMO's are related to the concept.
Your task will be to read a variety of websites/materials and find out what you can about GMO's then use that material to do the assignment. Your examples do not need to be positive or negative, just ways that the Biology concepts we've been working with tie into GMO's
For example, human beings are part of the food chain and GMO's may help in providing food for the ever growing population of humans.
This, of course is, also a way for you to find out more about GMO's before our upcoming "Great Debate Of 2017", where you will be charged with taking the helpful or harmful side of "Are genetically modified crops helpful or harmful to the human race?" You may want to bookmark any websites you come across that you feel will provide you a lot of information for the debate.
Good luck folks!

3/3 Biology update and homework due 3/17
Hi folks,
First off NO CLASS NEXT WEEK!
Today in Biology we took a fairly in depth look into how energy moves through an ecosystem. We discussed food chains, food webs and trophic levels. We also took advantage of the nice weather to play a game that emphasized some of the hardships of being a part of a food chain.
Homework for next week:
Read pgs. 366-369
Questions 10-17 on page 376
And
Questions 1 - 8 on page 377

2/24 Biology update and homework due 3/3
Hi folks,
Today we discussed ways that different species interact in their community. Unfortunately the book really doesn't cover this material so I'd like you to go to this page and read each page until you get to "Ecosystem Energy Flow". After reading the material, please answer the questions below.
Also, go to the following web page and do the activities there. Please write on a separate sheet of paper what the "journal" asks you to write on the screen.

1. What is a niche?
2. How would you describe your "niche"?
3. What is a niche made up of?
4. What does competition mean when it is applied to communities?
5. What is the difference between interspecific and intraspecific competition?
6. Name four things that species can compete for.
7. What is competitive exclusion?
8. What is resource partitioning?
9. Draw a predator/prey graph and explain what the graph is showing and why. (This isn't in the reading, use your notes for this one.)
10. What are three categories of prey defense adaptations?
11. What are the three main types of symbiotic interactions?
12. Give a definition and an example of the three types of symbiotic interactions.
13. Give a description of succession starting from colonizers and working up to climax communities.
