Which of the following could be considered a responsible way to manage a natural resource? a. replanting forests that have been cut down for lumber use b. dumping used chemicals into an isolated lake c. driving a gas-powered car everywhere d. growing the same crop every year on a plot of farm land

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.

d. groundwater flows through the subsoil and deposits minerals.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
