Question

what will happen there will be no animals in the world​

Answer 1

The earth would be become an ice ball.

Without animals plants would thrive greatly, their photosynthesis would use up the last “drop” of carbon dioxide, which would greatly weakens the greenhouse effect. Without sufficient greenhouse effect, the temperature of the earth would be far below ice point, and anything on the earth would be frozen. This actually has happened the in the real history. When the very first creatures that can conduct photosynthesis evolved, their natural enemies were far before their appearance, which makes them grow out of control. With the exhaust of carbon dioxide owing to their photosynthesis , the greenhouse effect was minimized, which resulted in the ice ball earth

If the entire Animalia kingdom had never existed on Earth, then all that would be left were bacteria cells, plant-related diseases, etc., and of course, plants. If it was impossible for a kingdom such as ours to happen on Earth, plant life (Plantae kingdom) might have evolved into some alien-like plant life/exotic plant species? Anyhow, it would be very different. Literally only the other five kingdoms would exist to some extent (there would only be Plantae, Eubacteria, Archaebacteria, Protista, and Fungi).

We’ll never know, but basically, if there were no animals (don’t forget, humans, or homo sapiens, are also animals), we wouldn’t exist. Earth would be an entirely different planet.
