response to stimuli
growth
adapting to the environment
asexual reproduction
3
When deforestation occurs in an area, what immediate effect does this have on the
water
cycle?
There is less runoff water, but more transpiration
CO2 begins increasing in the atmosphere
Less water is returned to the air by transpiration
More water is returned to the atmosphere by transpiration
4

a biome
a community
a population
an ecosystem
5

oxygen
ozone
water
6

herbivores
parasites
predators
8

increase
carbon dioxide in the atmosphere and contribute to the carbon cycle by

conserving energy with alternative energies
combustion from driving cars
planting trees to improve photosynthesis
9
