- How Temperature and Precipitation Affect Ecosystems
- The tropical rainforest is earth's most complex
biome in terms of both structure and species diversity.
- Tropical forests, covering
7% of the earth's surface area, contain perhaps 50% of the world's
- It occurs under optimal growing conditions:
abundant precipitation and year round warmth.
- There is no annual rhythm to the forest; rather
each species has evolved its own flowering and fruiting seasons.
- Sunlight is a major limiting factor. A variety of
strategies have been successful in the struggle to reach light or to
adapt to the low intensity of light beneath the canopy.
- Very poor soil forming processes. Not much
- Accumulation of CaCO3 at
- Alluvial Fan soil formation (1)
- What are grasses? Most economically important plant family.
- Between 9,000 - 10,000 annual and perennial species.

- Grass examples:
- Annual cool season grasses:
- Perennial cool season grasses:
- fescue, Kentucky Bluegrass, perennial ryegrass

- Perennial warm season grasses:
- big bluestem, bermudagrass, swtichgrass
