The correct answer should be<span> D) conserving natural resources without harming the environment
Instead of using new resources, you can use the waste from previous production and recycle it for the sake of creating something else, which preserves the resoruces and doesn't harm the environment.</span>
Salt reduces the amount of water in a solution, because you're introducing another molecule. If the water concentrations are different, the water is going to want to reach an equilibrium to balance itself out. Because the salt solution has a higher water concentration than the plant cell, the water will move into the cell to try and balance out the concentrations. If the salt solution had a lower water concentration (water potential) then water would move from the cell into the solution.
Answer: Pioneer Species
Explanation: Because they are part of a hardy species that whom are the first to move to a previously bio diverse steady ecosystem.
