Liu Wei: "The African grassland elephant is the largest elephant in the elephant family, about 20% larger than the African forest elephant, and about 30% larger than the Asian elephant.

As the largest mammal on land, the African grassland elephant has few natural enemies in its field of survival.

However, without natural enemies, does it mean that it is invincible? And where is it in the food chain?

Next, I will analyze these two issues in detail based on my knowledge. "

"First of all, we must understand the meaning of the food chain. The most straightforward explanation is that the food chain is a connection between living things in the ecosystem because of food, which is "the game where big fish eat small fish and small fish eat shrimp". .

In the food chain, plants are at the bottom, but they have the ability to convert inorganic matter into organic matter, providing the necessary nutrients for the survival of herbivores.

Therefore, we can think of plants as primary producers in the food chain.

Secondly, animals that feed on plants. They usually have a relatively high status in the food chain. We collectively call them herbivores. They are the first-level consumers in the food chain. The animal species in this class are huge and far from each other. It can be as small as the locust we see, or it can be as big as this grassland elephant in front of me.

Next, it is the carnivores that feed on herbivores.

The African grassland elephant is a pure herbivore. If it is classified according to our food chain, it belongs to the first-class consumer.

First-level consumers have a characteristic that they are food for second- and third-level consumers. From this point of view, the status of African grassland elephants is somewhat contrary to conventional logic.

The average weight of an adult African grassland elephant is close to 5 tons. This weight is 25 times that of an adult African lion. With such a huge difference in size, even a lion group dare not easily provoke the grassland elephant. Of course, there are also records of lions killing grassland elephants, most of which appeared before the grassland elephants matured.

We can see from this that although the African grassland elephant belongs to the first-level consumer, it is not satisfied with the progressive relationship of food for the second- and third-level consumers.

Therefore, we can think of the African grassland elephant as the top animal in the food chain, but it is only a herbivore. "

The audience hears a little

Roughly understand Liu Wei's meaning.

"Beyond it, rhinos and hippos are not satisfied with the progressive relationship of the food chain!"

"All the **** is a Big Mac, don't dare to mess with it!"

"Hippo is not a first-class consumer. Although it mainly feeds on aquatic plants, it also eats meat. It belongs to omnivorous animals!"

"The live room is so cultural!"

Liu Wei went on to say: "We then discuss the second question, is the African grassland elephant invincible?

It can be said that although the African grassland elephants have been madly slaughtered by poachers, its distribution range is still very wide, almost all over the African continent.

In terms of living space, it has a high degree of overlap with carnivores such as African lions, hyenas, and leopards.

However, because of the size difference, the leopards, the carnivores at the top of the African food chain, basically exclude adult male African elephants from their own recipes.

From this point of view, adult male African grassland elephants can be said to be natural enemies in the wild.

However, it has a powerful natural enemy on earth, that is, we humans. "

"Poof~, I knew it!"

"Humans are the natural enemies of all animals!"

"Should I be proud? Should I be sad?"

"Hey~, it's hard to say a word!"

Liu Wei’s [Yuyoushu www.uutxt.me] complexion also became serious, "Before the 1970s, the African grassland elephants began to suffer from human torture. At that time, the African indigenous people were more The huge grassland elephants were hunted for food, and a large number of elephants died under the traps and muzzles of the indigenous people. They only took elephant meat and elephant skin to eat and make simple daily necessities.

It was not until the 1970s that the ivory market began to rise, and the international crafts market began to acquire large quantities of ivory. After that, indigenous people killed elephants not only to eat meat and skin, but to take ivory to make money.

We know that the male African grassland elephant is the longest ivory of all elephants. When the ivory is treated as a gold bar, it has become the first target of human killing.

I remember when we talked about Asian elephants in science, we talked about a question. Will an elephant that has lost its ivory die?

The answer is not absolute. The ivory that we see with the naked eye is only a part of the entire length of the ivory. The thickest one-third is born on its head, and poachers often covet this part of the ivory, so they often hunt grassland elephants. After that, directly cut off its entire head and take away the inside part, which is extremely cruel! "

"Fuck, I can't listen anymore!"

"Is this Nima's job?"

"Sad!"

"Such a person must be sentenced to death!"

Liu Wei went on to say: "Actually, the ivory of African elephants grows for life. The exposed part is mainly composed of enamel and there is no neurovascular inside. If you only saw off the exposed part of the ivory, it will not be endangered. Elephant life.

You should have seen elephants with broken tusks in many documentaries. Their physical health has not been affected, but when fighting for spouse rights, they will be weaker than their counterparts.

In addition, elephant ivory has the function of assisting them to eat. Rupture of ivory will directly affect its eating. It may not be able to eat enough during the dry season when food is scarce.

Often these elephants will lose weight and grow old alone. "

Liu Wei touched the ivory of the prairie elephant. "We searched for ivory pictures on the Internet and found that there is a hollow hole in the upper end of the ivory. Only the whole ivory is taken out, because the exposed part is actually solid. And the end of the ivory hidden in the remaining third of the head directly links a large number of nerves and blood vessels.

If the whole ivory of an elephant is taken out, the elephant will definitely die.

So as long as the elephant is concerned about poaching, basically can't live. "

"Human hunting is an elephant's nightmare!"

"Ivory products are not our necessities. Have you killed them for an unnecessary thing? Too cruel!"

"Ivory products are too popular in the market, especially the rich!"

"No profit leads to no extinction!"

"I have watched a documentary about the massacre of African elephants, which is shocking!"

Liu Wei concluded: "Elephants are an important part of the entire earth's ecology, and we should not treat it with an unlimited demand.

my country has banned ivory trading in 2017, and the sale or purchase of ivory is punishable by up to ten years in prison.

However, the most funny thing is that some developed countries open their eyes and say that China is the largest ivory trading market. Actual data shows that the United States is the largest trading market, the United Kingdom is the largest reserve market, and Japan is the largest producer of ivory products. ! "

"Bah~, shameless!"

"Habitually black China!"

"His uncle, really when we were China a hundred years ago!"
