I think, it's not only about absorption. The sun emits black-body radiation, which has its maximum in the visible light. https://en.wikipedia.org/wiki/Planck%27s_law …
And that would also mean that other animals should have a similar range, right? Is that the case?
Yep. There's some variation. Sensing the low levels of thermal IR emitted by animals requires you to be cold-blooded (and cold at the time). I don't think any animals sense EUV, although it would be very easy to do.
Photosynthesis includes photochemical reactions in which chlorophyll absorbs typically 700nm light providing energy for electron transfers and ultimately the production of carbohydrates. Because the red light is absorbed, only the green light remains to be reflected to our eyes.
The most intense colour of the suns spectrum, green, is not used in photosynthesis. Explain the anomaly.
Or, less of a scientific leap, it was designed that way.
This was noted in 1744 by little known autodidact, Ponsonby Neckwattle (1718-1780), when he stormed the stage under the name Guillaume the Human Daffodil. He proclaimed “Je vous apparais comme une fleur renaître.”
