【An imaginary pyramid of the habits of living things.If the food chain is expressed in numbers…】

As for the food chain,roughly speaking,if it's a pyramid,it'll be composed of four classes like the next.😃

The fourth class is made up with green plants.The third one is herbivorous 肉食 animals.The second one is small flesh eating ones.The top one is large flesh eating ones.😃

The more going upward,the bigger the creatures's body become,the less their numbers are on the pyramid.All amount of food which the creatures eat don't form their bodies.

All amount of food which the creatures ate don't change into the creatures' body.It's just a tenth.Other nine-tenths is consumed for some activities of the creatures like breathing,other and so on.🐯

Let's think over a marine food chain of which top is tuna.The tuna is such a big fish that it's 3 meters long,and its weight is 400 kilograms.It has to eat lots of mackerels 鯖 so as to maintain its huge body.♓
