The soil of the rainforest is nutrient poor. How do plants that have roots in the rainforest floor obtain the nutrients they need? They absorb most of the nutrients they need from recently deceased plants and animals that fall on the forest floor.
They absorb most of the nutrients they need from the air.
They trap insects and gain nutrients they need by digesting the insects.
They have adapted to the poor soil of the rainforest and require fewer nutrients that they gain from the soil.

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization. a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution. part bcalculate the percent ionization of ha in a 0.010 m solution
