Decomposers, as the name suggests, decompose dead plants or animals into simple compounds. They feed on dead producers from the first levels or consumers from other three levels. Breaking them down, decomposers release nutrients that producers can use.
In an ecosystem with four levels, the first level are producers, such as plants and algae. On the second trophic level, there are primary consumers, herbivores that eat plants, for example, a deer, a rabbit, a grasshopper. The next trophic level belongs to secondary consumers that eat herbivores, for example, a wolf, a fox. The highest level is tertiary consumers that eat carnivores, for example, a bear, an eagle.
I believe that would be irritability.

Answer:
The regulation of the cell cycle helps in wound healing as well as replacing the lost cells by division. Thus, options B and C are correct.
Explanation:
The cell cycle can be described as the process of division and reproduction. The events result in the formation of multiple cells that have been able to deal with the repair mechanism of the body.
With the regulation of the cell cycle, the division process of the cell has been initiated and helps in the formation of multiple cells. The formed daughter cells have been able to heal the wounds effectively by accumulating and removing the dead cell.
The cell cycle has also been responsible for the replacement of lost cells, with the formation of new cells. Thus, options B and C are correct.
Answer:
When a mustard plant seedling is transferred to an environment with higher levels of carbon dioxide, the new leaves have a lower stomata-to-surface-area ratio, it is because the concentration of carbondioxide is high in the surrounding so the plant produce small leaves having less number of stomata. If the concentration of carbondioxide is lower so big leaves are produced having maximum number of stomata.
