2. Abiotic Factors
Tropical rain forest is hot all year long, the climate is warm and stable, very good for organisms to live.
Because plants are intensive, some understory plants can’t get enough sunlight.
Tropical rain forest also has adequate rain water.

3. Biotic Factors Plant Life
canopy-the extent of the outer layer of leaves
understory-the area of a forest which grows at the lowest height level below the forest canopy（use large leave to competefor limited light)
Animal Life(active all year)
animals various,most are small animals and dendrocole(animals who live in the tree)
comouflage-help animals to hide themelves

4. Distribution Across the equator, North and south latitude 10 degrees.
The terrain, the atmospheric circulation and ocean currents affect areas have a tropical rain forest form.
Damp and hot
Economy is backward, not fit for human habitation.

6. Abiotic Factors
Rainfall in tropical and subtropical grasslands, savannas, and shrublands is between 500 and 1300 millimeters (20 to 50 inches) a year.
The climate varies, with an average temperature of 27 °C with peaks of 30 °C in April and October.
Compact soils.
Frequent fires set by lightning.

7. Biotic Factors Bread-fruit Tree
Plant adaptations include waxy leaf coverings and seasonal leaf loss.
Bread-fruit Tree
Many animals migrate during the dry season to find water .Some smaller animals burrow and remain inactive during the dry season.
Zebra
Orycteropus afer
Ostrich

8. Distribution Occur on all continents but Antarctica Africa South Asia
Northern parts of South America and Australia
