Agriculture just became easier. It was much easier and safer than directly hunting, albeit, it wasn’t always as rewarding, but it was much more reliable. If you could hold off until the large crop was fully grown with hunting, you could rely on the large crop while waiting for the next one, and have a berth large growth. In other words, it was more reliable, easier, and could be very lucrative.

Answer:
The cell organelles are the functional structures present inside the cell. Some of the organelles such as nucleus, mitochondria, chloroplast, Endoplasmic Reticulum, Golgi Complex etc are membrane-bound. Each organelle inside the cell has a different function to carry out. For example, the nucleus is the organelles which stores and protects the genetic material. Ribosomes are the organelles where a protein is formed. The Golgi- complex is the site where the proteins are modified and packaged.

Explanation:
In an ecosystem, energy is transferred from one organism occupying a trophic level to another as they feed on one another. The amount of energy that is being transferred as the chain progresses is called ECOLOGICAL EFFICIENCY. According to this question, the ecological efficiency at each trophic level of the ecosystem is 20%. This means that about 20% of energy units will be transferred to the next trophic level.
If the green plants of the ecosystem capture 100 units of energy, the amount of energy that will be available to support herbivores (plant eaters) is: 20% × 100units i.e. 20/100 × 100 = 20 units.
Also, the amount of energy that will be available to support carnivores subsequently will be 20% of 20 units i.e. 20/100 × 20 = 4 units.
