Answer:
Option A, Donates H+ ions when conditions become too basic and accepts H+ ions when conditions become too acidic
Explanation:
Buffer solutions have the ability to maintain stability of pH of the solution. They resist any changes in the pH of the solution on addition of an acid or a base component or solution.
Every buffer solution has a buffer capacity and range. Buffer capacity depicts the amount of acid or base solution is required to change the pH of the solution by 1
.
Hence, option E is correct
Ecosystems maintain themselves by cycling energy and nutrients obtained from external sources. At the first trophic level<span>, </span>primary producers<span> (plants, algae, and some bacteria) use solar energy to produce organic plant material through photosynthesis. Herbivores—animals that feed solely on plants—make up the second trophic level. Predators that eat herbivores comprise the third trophic level; if larger predators are present, they represent still higher trophic levels. Organisms that feed at several trophic levels (for example, grizzly bears that eat berries and salmon) are classified at the highest of the trophic levels at which they feed. Decomposers, which include bacteria, fungi, molds, worms, and insects, break down wastes and dead organisms and return nutrients to the soil
