Every breath of air human beings has to thank this creature, do you know why?

The earth has a relatively long history since its birth. Now there are many species on the earth, and each creature has its own form and its own living environment. And all creatures on the earth are in an ecological circle, and each species plays its own role in the ecological circle. Today, I will tell you about whales.

1. What role do whales play in the ecology of the earth?

Whales are behemoths that live in the ocean. In the ocean, whales are the overlords. Because this creature is so big that it can eat more than a dozen sharks with just one mouth, the creatures in the ocean are more afraid of whales.

But whales are very important to the entire ocean system. The lifespan of a blue whale is about 80 to 90 years. They can absorb a large amount of carbon in the ocean, effectively slowing down global warming.

And the value of a whale after death is equally great. There are many species living in the ocean. When a whale dies, its corpse can provide energy to more than 400 kinds of marine life.

There is a saying: "When a whale falls, all things are born." The fall of a whale has nurtured at least tens of thousands of marine life, and the whale's body will sink to the bottom of the sea. The bottom of the sea is usually a place where materials are scarce, and the arrival of the whale remains is equivalent to the discovery of an oasis in the desert , which can sustain the nourishment of these seabed creatures for 100 years.

2. Why is whale feces a "priceless" treasure?

After talking about the whale, let's talk about its feces. Defecation is a normal thing for living things. After the food is digested and decomposed in the intestine, it will be metabolized in the form of defecation , but the feces of whales are for the ecology of the earth. But has an important role.

When whales defecate, they will dive to the sea surface. These feces contain a lot of nutrients, which can provide energy sources for plankton on the ocean surface, and also stimulate the growth of phytoplankton.

Because whales also make long-distance migrations in the ocean, and this creature has the longest migration of all mammals. Whales like to hunt in areas with abundant food resources, and then give birth and brood in areas with less resources.

In the process of migration, whales unknowingly bring nutrients to areas where resources are scarce, which just happens to promote the energy exchange between the oceans.

Although plankton is inconspicuous compared to other large fish, these plankton are indeed the basis of the marine ecological chain.

If the ocean lacks plankton, it will be difficult for other marine life to survive. There are a lot of plankton in the sea that rely on whale feces to survive, so whales play a role in stabilizing plankton.

In addition, phytoplankton also has the effect of fixing carbon elements. The number of phytoplankton growing in the sea is huge, and these phytoplankton will absorb a large amount of carbon dioxide on the earth, so in this regard, global warming is also effectively reduced.

The plankton in the ocean also provides a lot of oxygen to the earth. Some studies have found that 70% of the oxygen on the earth comes from the ocean. The survival of these plankton depends on the feces of whales, so it is said that whale feces are invaluable to the ecology of the earth.
