a single species that is vital in ecosystem stability
a species who lives in a special habitat called keystones
a single species that is not vital in ecosystem stability
16
What causes acid rain?
using external biological factors to biological factor external factors
using fossil fuels releases nitrogen and sulfur and combine to fall as rain
ozone molecules combining with water vapor which fall and kill plants
17

lower temperatures
less direct sunlight
more organic matter in the soil
more precipitation
