sentence: Insects land on the leaf, are caught by the surface tension of the water, and suffocate.
sentences_before: Hairy leaves do catch and hold drops of rainwater, which helps bacterial growth.
sentences_after: Bacteria start to decay the insect, and release nutrients from the corpse. The plant then absorbs the nutrients through its leaves. This 'leaf feeding' can be found in many non-carnivorous plants. Rainwater can be retained by cupping the leaf, leading to pitfall traps. Alternatively, insects can be caught by making the leaf stickier, leading to flypaper traps.
