We do not see the bodies of living beings/animals after their natural death. For example, snakes, foxes and birds. Where and how are their bodies buried?

 When animals in the wild die naturally, their bodies are typically left to decompose on the ground or are scavenged by other animals. The specific fate of an animal's body after death can vary depending on factors such as the ecosystem, climate, and the presence of scavengers.

In many cases, the bodies of small animals like birds, snakes, or foxes may be quickly decomposed and consumed by scavengers, such as carrion-eating birds, insects, or mammals. These scavengers play an important role in recycling nutrients back into the ecosystem.

In some cases, animals may seek shelter or hidden areas when they are near death or dying. This can include burrows, dens, thick vegetation, or other secluded spots. If an animal dies in such a location, its body may remain hidden or may decompose within that environment.

It's important to note that natural processes take care of the decomposition and recycling of animal remains in the wild. Unlike human practices of formal burial, animals do not engage in deliberate burial rituals. Instead, nature's processes ensure the return of nutrients to the ecosystem.

It's worth mentioning that there can be cultural or religious practices among humans involving the burial or cremation of animals, but those are specific to human traditions and not natural processes in the wild.
