28 and 29.... modified root and biome

This underwater shot of a river demonstrates a biome(big idea 4 # 3). This specificly is a freshwater river, one which has its own native climate, plant life, temperature, and animal life. The factors that compose a biome are latitude, humidity, and altitude. These are less important for aquatic biomes than land biomes, with several other factors contributing including turbidity, current speed, depth, andhow far the location is from the source or delta.
This tree is located along the side of the river where it floods often, making it necessary for the tree to have a modified root(big idea 1 #29). When the water level receeds, it is visible that  these roots are very tall and originate from the tree roughly 18 inches above the surface. This is a common yet not extreme for of stilt root. These grow along the surface a ways before growing undergrond as a means of support against forces put on the tree...ie flowing water.

  1. Ryan, you're awesome! It looks like you are leading this race where there may be bonuses for the first three finishers. Where is Lil' Buddha in the river?
