The correct answer is - 1) inverted pyramid, with a narrow base representing a small number of young individuals.
The populations that are decreasing are usually population in countries that are highly developed. The conditions for living are excellent, the medical care on high level, life expectancy very high, but the birth rates very low.
In this type of conditions, there's smaller and smaller number of young individuals, with the middle aged population being much bigger, and the older population being constantly on the rise. This will give the age-structure histogram a reverse shape than what it is supposed to have, it will be similar in appearance like a inverted pyramid, meaning that the population is aging and that it will be constantly on a decline in the future.

Answer:
The correct answer is - aerial view of the fault line of San Andreas which represents a transform or strike-slip type of boundary.
Explanation:
The picture is given in the question is an aerial view of the fault line of San Andreas.
A fault is a planar break or intermittence in a volume of rock across due to rock-mass movement that leads to significant relocation or displacement. In San Andreas, the faultline represents the transform or strike-slip type of boundary.
Observation:
- A complex zone of crushed and broken rock
- Many smaller faults branch
Trophic cascades are interactions with much power that control an entire ecosystem when suppressed
