Answer: Because of the Food Chain, the sequence of transfers of matter and energy from organism to organism.
Explanation:
Mice eat all kinds of vegetation, including grass. From there they obtain the necessary nutrients to carry out the cellular respiration that will produce energy for the vital physiological processes of the animal. Then, a carnivorous animal like a fox will feed on that mouse. And so it will in turn use it to obtain the nutrients and energy necessary to stay alive. Then, the fox fed on the mouse that first fed on the grass. Then, the grass indirectly and through the food chain (which is a linear network of links in a food web starting from the mice and ending at the fox ), was important in feeding the fox.
