That's a good way to think about it, but it's not entirely accurate. Here's a breakdown:

Biological death is a complex process involving multiple stages, and the cessation of metabolic processes is only one aspect of it.

Here's why:

* Metabolic processes involve the chemical reactions necessary for life. These processes slow down and eventually cease during death. However, some cells may continue metabolic activity for a short time after the heart stops beating.

* Other defining features of biological death include:

* Irreversible cessation of brain activity. This is often considered the most important indicator of death.

* Loss of homeostasis. The body's ability to maintain a stable internal environment is lost.

* Cell death. Individual cells within the body start to die and decompose.

In simpler terms: While the termination of metabolic processes is a significant part of biological death, it's not the only thing that defines it. It's more about the overall irreversible loss of life functions, especially the brain's activity.
