If one is interested in understanding, in a detailed and comprehensive way, how ecosystems and the living beings within them function (both in themselves and in relation to their environment), how much physics and mathematics is it useful to know? Are there any textbooks that contain all the necessary physics and mathematics specifically calibrated for this?

Between the 18th and 19th centuries, zoology was a prominent science. Today, I have the impression that it is in academic decline, fragmented into Molecular Biology and Genetics, Ecology and Conservation Biology, and Ethology. Studying the individual animal for its own sake no longer seems to be of interest; instead, it is reduced to a mechanism whose parts are studied, or to a mere component of an ecosystem. Am I wrong?

There seems to be a complete disconnect between the animal as an object of emotional or spectacular consumption and the actual scientific study of the species. Science is not stories, but data. Suppose there were a comparative anatomy documentary regarding the excretory system of mammals; who would the audience be?
