3/13 Biology update and homework due 3/20

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.  What are three categories of prey defense adaptations?



10.  What are the three main types of symbiotic interactions?



11.  Give a definition and an example of the three types of symbiotic interactions.



12. Give a description of succession starting from colonizers and working up to climax communities.

5/1 Biology class and homework due 5/8

  Hi folks, We got into the plant kingdom today and got into some of the basic classifications and into the purposes of some plant parts.  We will get into this a bit deeper next week if we have time. I've include the pictures from this week's lecture as well.  You'll notice that I put the monocot vs dicot table on  there for you as well. There will be a quiz on archaea, bacteria and what we've covered so far in plants so be sure to spend some time with that.  Be sure to focus some time on the differences between monocot and dicot plants. For homework next week read pages 583-602. Do questions 1 - 18 on page 604.
