Question

What is the total amount of matter in an ecosystem doing? always changing always increasing always decreasing remaining the same

Answer 1

It remains the same.

Step-by-step explanation:

The question is kind of off though because the matter in an ecosystem can change, but not in amount forms. For example, an ice cube could change into water, but the matter doesn't increase or decrease.

The matter therefore remains the same.

(I had this on my quiz too, so I did research.)

Answer 2

Remaining the same

Step-by-step explanation:

By the Lavoisier's principle the matter can't be created nor destroyed, but always transformed.

It means that in an ecosystem, the matter, and also the energy, is not increasing and not decreasing, the total amount remains the same, but in different forms.
