BIO 1100 IV DISCUSSION BOARD QUESTION
Think about the ecological biome that you currently live in or grew up in. How would you classify it – temperate forest, temperate grassland, etc.?
For inspiration, see Chapter 16 of our course textbook and The World’s Biomes Page. If you can, post an image taken from your biome of dominant features of your landscape (but please compress your image to ca. 25 to 33% of original size so that the discussion board formatting in Blackboard is not overwhelmed). Please put some good effort in describing your landscape. Posts that say “My landscape is grass and lawns with dogs and cats running around” will not contribute significantly to this discussion and will be graded accordingly.

Lawns are being over-fertilized, causing excess fertilizer to wash into the pond, stimulating algal growth. |
||
The low reflectance of the surrounding area is heating up the pond, causing increased algal growth. |
||
The salting of the roads during icy conditions in the winter has resulted in the runoff of salt, which stimulated algal growth. |

Ecology
Introduction
In previous chapters, we learned that life is very diverse. Organisms range from single cells to multi-celled. Some organisms cannot even be seen with the naked eye. Is diversity increasing or decreasing? In the future, will we have more organisms? Does our population play a role in the lives of other organisms? Should we be considered if an organism goes extinct? The following exploratory activity will help you understand threats to organisms, what is being done to save them, and how organisms are classified.
