BIOMES


A biome is the collective name for the biotic characteristics (set of organisms) that tend to be associated with a particular climate region.

1) compare and contrast the terms biotic & abiotic

2) tell whether each factor listed is a biotic or an abiotic characteristic of an ecosystem:

a. 10 inches of precipitation per year
b. large coniferous trees
c. mammals and reptiles
d. average high of 80 degrees F in June
e. wind speeds of below 80 mph
f. no snakes

3) Compare and contrast structural adaptations vs. behavioral adaptations that organisms rely upon to survive their environments.
