commensalism
mutualism
8
what are biomes?
role or job in a community
using resources
large group of ecosystems that share the same climate

soil
fungi
animals
12
Factors that prevent population growth are called
Limiting Factors
Population Factors
Stop Factors
Growth Factors
13
What is the formula for population density?
Density = 70 / Growth Rate
Density = Population Size / Area of Space
Density = (Birth Rate + Death Rate) / Total Population
Density = Population Size / Sum of All Populations
