A key stone species is..
a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically. （Ex. Ochre Sea Star, California Mussel)
species that are native to and found only within a limited area
a species that has a strong role in structuring a community. A foundation species can occupy any trophic level in a food web (i.e., they can be primary producers, herbivores or predators Ex. kelp).
Species with a broad ecological niche. They can live in many different places, eat a variety of foods, and tolerate a wide range of environmental conditions. (Ex. flies, human)
A biome is a large area with similar___ conditions that determine___ there
altitude/ species
climate/ plants and animals

Movement of molecules that contain carbon, glucose, and methane
leads to imbalance in which reservoirs or sinks are storing carbon
What does photosynthesis do?
Removes CO2 from the atmosphere and converts it to glucose
Removes CH4 from the atmosphere and converts it to glucose

plants and animals taking nitrogen in and expelling it from their body
plants and animals taking nitrogen in and incorporating it into their body
What is ammonification?
Soil bacteria, microbes and decomposers converting waste and dead biomass back into NH3 and returning it to soil
The conversion of NH3 into nitrite and then nitrate by soil bacteria
Conversion of soil NO3 into N2O gas which returns to the atmosphere
Plants and animals taking nitrogen in and incorporating it into their body
What is nitrification?
Plant roots take in NO3 or NH3 from the soil
Soil bacteria, microbes, and decomposers converting waste and dead biomass back into NH3 and returning it into the soil
