Perpetual, Renewable, Nonrenewable
be around for a long time - sun, wind, tide, geothermal, flowing water
can be used over and over again - fresh air, water, soil, organisms
"to nest", how and where an organism lives; many microhabitats within
ecosystems which impact survival
Examples of microhabitats
land ecosystem - (transitional) - aquatic ecosystem = when desert meets
what is an ecotone
describe the climate of deserts
hot, dry, low precipitation, mixed stability and high winds; no cloud cover
creates more extreme temperatures
types of global deserts
1. semi arid - not as dry, more plants 2. arid - very dry with no plant

Hypersensitivity Disease where Mast Cells (in epithelial tissues) release chemicals
that attack pathogens, sometimes they react when they are not supposed to.
