question 16 (5 points)
which of the following is a sustainable practice?
a) throwing jars in the trash can

b) using only geothermal energy

c) leavine trash baes at a local oark

Explanation:

First Question (about population)

When a country develops and birth/death rates stabilize (birth rate ≈ death rate), population growth is zero. Options A (only birth) and C (only death) are incomplete. The age - structure model is about population age distribution, not stabilization. So zero population growth matches.

Second Question (about sustainable practice)

Geothermal energy is renewable and sustainable. Throwing jars in trash (A) and leaving trash at a park (C) are wasteful/harmful to the environment, not sustainable. Using geothermal energy (a renewable resource) is a sustainable practice.

Answer:

D) zero population growth.
