Question: A tropical rain forest contains many tall trees. Smaller plants with large leaves grow at the base of the tall trees. The large leaves are most likely an adaptation of the plant due to which condition?
Answer: lack of sunlight
Hypothesis: plants on tropical rainforest floors grow large leaves due to the low availability of sunlight
Supporting facts: sent1: as the size of a leaf increases , the amount of sunlight absorbed by that leaf will increase sent2: an adaptation / an ability has a positive impact on an animal 's / living thing 's survival / health / ability to reproduce sent3: large canopies / trees block sunlight from reaching the ground sent4: forest canopies blocking sunlight decreases the availability of sunlight on the forest floor sent5: larger means greater / higher / more / increase in size sent6: a leaf is a part of a green plant sent7: tropical rainforests contain many large trees sent8: a plant requires sunlight for photosynthesis sent9: a leaf absorbs sunlight to perform photosynthesis sent10: a plant is a kind of living thing sent11: a required resource being low in availability has a negative impact on the something that requires that resource sent12: a plant requires photosynthesis to grow / survive sent13: if a living thing must do something to survive, then increasing that living thing's ability to do that something has a positive impact on that living thing's survival
Reasoning: [BECAUSE] large canopies / trees block sunlight from reaching the ground [AND] tropical rainforests contain many large trees [INFER] int1: sunlight is blocked by large canopies / trees in rainforests [BECAUSE] int1 [AND] forest canopies blocking sunlight decreases the availability of sunlight on the forest floor [INFER] int2: tropical rainforest floors are low in availability of sunlight [BECAUSE] a required resource being low in availability has a negative impact on the something that requires that resource [AND] a plant requires sunlight for photosynthesis [INFER] int3: a low availability of sunlight has a negative impact on plants [BECAUSE] int2 [AND] int3 [INFER] int4: low availability of sunlight has a negative impact on plants in tropical rainforest floors [BECAUSE] as the size of a leaf increases , the amount of sunlight absorbed by that leaf will increase [AND] larger means greater / higher / more / increase in size [INFER] int5: large leaves increase a plant's ability to absorb sunlight [BECAUSE] a leaf is a part of a green plant [AND] a leaf absorbs sunlight to perform photosynthesis [INFER] int6: a plant absorbs sunlight with its leaves to perform photosynthesis [BECAUSE] int6 [AND] a plant requires photosynthesis to grow / survive [INFER] int7: a plant must absorb sunlight with its leaves to survive [BECAUSE] a plant is a kind of living thing [AND] if a living thing must do something to survive, then increasing that living thing's ability to do that something has a positive impact on that living thing's survival [INFER] int8: if a plant must do something to survive, then increasing that plant's ability to do that something has a positive impact on that plant's survival [BECAUSE] int7 [AND] int8 [INFER] int9: increasing a plant's ability to absorb sunlight with its leaves has a positive impact on that plant's survival [BECAUSE] int5 [AND] int9 [INFER] int10: large leaves have a positive impact on a plant's survival by increasing that plant's ability to absorb sunlight [BECAUSE] int10 [AND] an adaptation / an ability has a positive impact on an animal 's / living thing 's survival / health / ability to reproduce [INFER] int11: large leaves are a kind of adaptation for absorbing sunlight [BECAUSE] int11 [AND] int4 [INFER] int12: plants on tropical rainforest floors grow large leaves due to the low availability of sunlight
