Question: A windstorm knocks down many trees in a national park. Timber companies want to get rid of the fallen trees. How would this most likely harm the park ecosystem?
Answer: removes available nutrients
Hypothesis: removing fallen trees harms an ecosystem by removing available nutrients
Supporting facts: sent1: an environment is a kind of ecosystem sent2: if a living thing requires something then that something has a positive impact on that living thing sent3: using resources decreases those resources sent4: decomposition increases the amount of nutrients / nitrogen in the soil sent5: organisms are a part of an environment sent6: soil provides nutrients for plants sent7: a forest contains lots of plants / trees sent8: removing dead organisms from an ecosystem causes available nutrients to be removed from that ecosystem sent9: weeds use up nutrients sent10: decreasing something positive has a negative impact on a thing sent11: a plant is a kind of organism sent12: nitrogen is a kind of nutrient for plant growth sent13: a plant / living thing requires nutrients to grow sent14: a living thing is an organism sent15: wildfire decreases / removes the nutrients in soil sometimes sent16: decomposition is when a decomposer recycles / returns nutrients / nitrogen from dead organisms to the soil by eating those dead organisms sent17: fallen trees are a kind of dead organism sent18: removing something positive has a negative impact on the things that are positively impacted by that something sent19: the amount of something is similar to the availability of something sent20: harming something has a negative impact on / effect on that something sent21: roots are a vehicle for absorbing water and nutrients from soil into the plant sent22: soil contains nutrients for plants sent23: using less of a resource increases the availability of that resource sent24: removing an inhibitor of a process causes that process sent25: if a leaf falls off of a tree then that leaf is dead
Reasoning: [BECAUSE] fallen trees are a kind of dead organism [AND] removing dead organisms from an ecosystem causes available nutrients to be removed from that ecosystem [INFER] int1: removing fallen trees from an ecosystem causes available nutrients to be removed from that ecosystem [BECAUSE] a plant is a kind of organism [AND] a plant / living thing requires nutrients to grow [INFER] int2: organisms require nutrients to grow [BECAUSE] a living thing is an organism [AND] if a living thing requires something then that something has a positive impact on that living thing [INFER] int3: if an organism requires something then that something has a positive impact on that organism [BECAUSE] int2 [AND] int3 [INFER] int4: nutrients have a positive impact on organisms [BECAUSE] int4 [AND] organisms are a part of an environment [INFER] int5: nutrients have a positive impact on the environment [BECAUSE] int5 [AND] removing something positive has a negative impact on the things that are positively impacted by that something [INFER] int6: removing nutrients has a negative impact on the environment [BECAUSE] int6 [AND] harming something has a negative impact on / effect on that something [INFER] int7: removing nutrients harms the environment [BECAUSE] int7 [AND] an environment is a kind of ecosystem [INFER] int8: removing nutrients harms an ecosystem [BECAUSE] int1 [AND] int8 [INFER] int9: removing fallen trees harms an ecosystem by removing available nutrients
