When something is alive, there are chemical reactions going on constantly within it. The technical definition of being deadis that of chemical equilibrium. When a system (for example, a beaker with chemicals inside it, or an animal) is in chemical equilibrium, there is no reaction that can take place without an input of energy. Since an animal in chemical equilibrim cannot do anything, it is considered completely dead.
So, in short, dying (that is, ceasing to be alive) is nota chemical change. Instead, dying is a lack of chemical change.

Is a leaf changing colors a chemical or physical change?
Leaves change colour because the green pigment (chlorophyll) is degraded, then other pigments like anthocyanins (red or purple) and carotenoids (yellow) are exposed. So the change is more chemical than physical. Leaves going brown are also caused by chemical changes, but it also means the leaf cells are dead or dying.
Rotting of dead animal is a chemical change or not?
Yes, the decomposition of organic material is a chemical process.
Do most carnivores and omnivores eat their own dead e.g. would a mouse eat a dead mouse or a lion a dead lion?
Sometimes. A lion who has just given birth may eat any stillborn cubs to produce milk for her alive cubs. I do not know about mice!
When dead plants and animals decompose what happens to the matter that it made of?
When they die, they decompose and mix with the soil.

Once I saw a slug eating a dead snail. I have photos of a slug eating a dead mouse! They're clearly carnivores!
Dead coral reef is pounded by waves into beach sand a physical or a chemical change?
Physical change
Is decaying matter a physical or chemical change?
It's a chemical change. A chemical change is any change that causes a substance to change into another substance. A sign to know whether it's a chemical change or not, are the changes in odor. When something decays the change in smell is very powerful. Therefore, it is a chemical change.
Does a dead mouse emit toxic fumes?
A dead mouse may emit toxic fumes if it was killed by a chemical or pesticide. These can be released through decomposition.

When a cat eats a mouse - is the mouse dead or alive?
The mouse is dead... cats will usually play with the mouse until they kill it then eat it
Is a brown apple a chemical change?
An apple turning brown is both a chemical and a physical change. Physically it changes appearance by turning brown. Chemically it oxidizes when the air comes in contact with the enzymes and chemicals in the fruit.
Is mixing vinegar and baking soda a chemical or physical change and why?
Chemical. Vinegar is acidic - bicarniate when acidified produces carbon dioxide which bubbles out. This is a chemical change because the end-products (carbon dioxide, sodium acetate) are different species than the reactants (sodium bicarbonate, acetic acid). It is impossible to regain the initial state without the addition of new chemicals into the system. A physical change would be the freezing of vinegar. The reactants and the products are the same species (vinegar), and the initial state (liquid) can be regained by allowing the frozen vinegar to thaw.
