Question

hydrothermal vents are often rich in metals, such as copper, and also host dense populations of marine organisms. which of the following is clearly a non - renewable resource: copper, crabs, and/or mussels?
all of them are completely non - renewable.
copper and mussels are clearly non - renewable.
copper is the most clearly non - renewable.
mussels and crabs are the most clearly non - renewable.

Explanation:

Renewable resources can be replenished naturally over time. Crabs and mussels are living organisms that can reproduce, making them renewable. Copper is a metal ore, and its formation takes extremely long geological time - scales and is not replenished quickly on a human - relevant time scale, so it is non - renewable.

Answer:

Copper is the most clearly non - renewable.
