What does Abiotic and Biotic mean
Abiotic-Non-living components in an ecosystem
Biotic-Living components in an ecosystem
What is a biome

Describe the location of biomes
Tropical Rainforest-Found along the equator
Desert biome-Found near the Tropics of cancer and the Tropics of Capricorn
Taiga biome-Found in Russia and Canada
What 2 factors determine a biome
Temperature and precipitation
What climatic Factors determine the characteristics of each biome
Temperature- Decay and growth happens slower in colder temps but its hot and humid at the equator so lots of vegetation
Altitude-The higher the altitude the lower the temperature which leads to less vegetation and decrease of animals and the thinning of soil
Geology-Permeable rocks absorb a lot of water however the soul underneath could get waterlogged However non-permeable rocks could lead to flooding and it does not allow growth
Who are indigenous people

Leaves fall to the ground {litter}
Leaves decompose and break down
The nutrients are the absorbed by the tree for growth
How does the biosphere regulate the water cycle
The biosphere regulates the water cycle through process like transpiration, evaporation, and precipitation
