Question: One effect of ocean pollution is that it can reduce populations of phytoplankton and algae. The reduction of these populations might have which impact on an ecosystem?
Answer: decreasing the amount of oxygen being produced
Hypothesis: ocean pollution can cause the amount of oxygen to decrease in the ocean
Supporting facts: sent1: if something is a source of something else then that something usually contains that something else sent2: water pollution is when humans pollute the environment with pollutants sent3: algae is a kind of plant sent4: phytoplankton is a kind of plant sent5: an ocean is a kind of body of water sent6: to be a source of something means to cause that something sent7: decreasing something positive has a negative impact on a thing sent8: phytoplanktons are found in bodies of water sent9: green marine algae are a kind of producer sent10: algae is found in bodies of water sent11: ocean pollution can decrease the number of phytoplanktons and algae sent12: controlling the amount of pollution is similar to reducing the amount of pollution sent13: as the population of algae increases , the amount of available oxygen for fish will decrease sent14: decreasing something negative has a positive impact on a thing sent15: as the size of a source of something increases , the amount of something that source produces will decrease sent16: a source of something increases the amount of that something sent17: the decrease of something required by an organism has a negative impact on that organism 's survival / that organism 's ability sent18: if something emits something else then that something increases the amount of that something else sent19: plants are a source of oxygen through photosynthesis sent20: pollution has a negative impact on the environment / air quality / water quality / society sent21: as the amount of a source of something decreases , the amount of that something will decrease sent22: as a population of organisms increases , the resources used by those organisms will decrease sent23: if an object / a substance makes something then that object / that substance is a source of that thing sent24: if something has a negative impact on something else then increasing the amount of that something has a negative impact on that something else sent25: preventing something decreases the amount of that something
Reasoning: [BECAUSE] phytoplankton is a kind of plant [AND] an ocean is a kind of body of water [AND] phytoplanktons are found in bodies of water [INFER] int1: phytoplanktons are plants that can be found in the ocean [BECAUSE] algae is found in bodies of water [AND] algae is a kind of plant [AND] an ocean is a kind of body of water [INFER] int2: algae is a plant that can be found in the ocean [BECAUSE] int1 [AND] int2 [INFER] int3: phytoplanktons and algae are plants that can be found in the ocean [BECAUSE] int3 [AND] plants are a source of oxygen through photosynthesis [INFER] int4: phytoplanktons and algae are source of oxygen in the ocean [BECAUSE] int4 [AND] ocean pollution can decrease the number of phytoplanktons and algae [INFER] int5: ocean pollution can decrease the source of oxygen in the ocean [BECAUSE] int5 [AND] as the amount of a source of something decreases , the amount of that something will decrease [INFER] int6: ocean pollution can cause the amount of oxygen to decrease in the ocean
