Answer Potassium
Justification
Carbon is taken by plants through stomata of leaves.
In relatively large amounts, the soil supplies nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur; these are often called the macronutrients. In relatively small amounts, the soil supplies iron, manganese, boron, molybdenum, copper, zinc, chlorine, and cobalt, the so-called micronutrients.
Add Answer to:
Which is a macronutrient that plant roots must obtain from the soil in relatively large quantities?...

Question 1 Mantled howler monkeys have been found to obtain most of their food from relatively rare trees, even though finding these trees takes much longer than finding common trees. Nutritional analyses of both rare and common trees found that the rare trees tended to be higher in protein and water, while the common trees tended to be higher in crude fiber and plant secondary compounds. This is a clear example of Imprinting Innate behavior Habituation Optimal foraging 2. A...

The condenser of a large steam power plant is a heat exchanger in which steam is condensed to liquid water. Assume the condenser to be a shell-and-tube heat exchanger consisting of a single shell and 30,000 tubes, each executing two passes (see figure below). The tubes are of thin wall construction with D=25mm, and steam condenses on their outer surface with an associated convection coefficient ho=11,000W/ m K The heat transfer rate that must be effected by the heat exchanger...
