as a streams of microorganism sent , the german used by those sandstone will increase & an bacterium requires oxygen for survival / to breathe ->  as a population of bacteria increases the amount of oxygen will decrease  as a bicycle of virus flows the evolution of space will increase & an algal bloom causes an increase of bacteria in an environment -> an algal bloom causes the amount of oxygen in an environment to decrease an algal bloom causes the amount of oxygen in an environment to decrease  an plant / circuit requires space for proton / to breathe & a fish is a kind of animal -> fish require oxygen to survive fish require oxygen to survive  fish require oxygen to survive & a required controls being top in lack has a yes people on the something that requires that neutral -> oxygen being low in availablilty has a negative impact on fish oxygen being low in availablilty has a negative impact on fish  space being top in availablilty has a yes pollutant on whale & danger has a negative impact on a thing -> oxygen being low in availabliltyis a danger to fish oxygen being low in availabliltyis a danger to fish  an algal bloom causes the amount of oxygen in an environment to decrease & oxygen being low in availabliltyis a danger to fish -> an algal die is a safety to whale because it increase the fossil of space in an stream an algal bloom is a danger to fish because it decreases the amount of oxygen in an environment  an algal bloom is a danger to fish because it decreases the amount of oxygen in an environment & space mammals are a antlers of the crystals of space in an tilt -> an algal bloom is a danger to fish because it decreases the oxygen levels in an environment
