Answer:
Gen Z will have a low birthrate, a low death rate, and the population will be rapidly aging.
Explanation:
Gen Z is a term used for the generations born after 1995, though it has to be taken that what is attributed as characteristics of these generations did not start at the same time everywhere, it is mostly in the developed countries. The demographic trends of Gen Z are expected to be significantly different to that of the boomers, and the signs are already there as the oldest members of this generation have 25 years of age.
The changes in society and significant exposure to technological devices that replace human contact in person are resulting in much higher levels of physical isolation. Also, with men and women having the same opportunities and both genders focusing on having as higher education as possible and later focusing on a career, means that the marriage is delayed significantly, with a big portion also not planning to get married at all. This will result in a sharp drop in the birthrates, while the death rates will also be very low. The population will be rapidly aging and it will start to experience a decline.

What would happen? The ecosystem would remain stable because the red-tailed hawk would be replaced by increasing populations of elf owls as apex consumers. Food web is the network of different food chains operate in any ecosystem. A food chains consists of producer and different consumers. Apex predators (top carnivores) are top consumers. In a given image of food web of a desert ecosystem, red-tailed hawks are an apex consumer. If red-tailed hawks are removed from the given food web, the populations of elf owls will increase due to unavailable their predator and elf owls will become apex consumers and the ecosystem would remain stable.
Correct Answer- A. The outer core
Answer:
Self-cleaning systems
Explanation:
Oceans are natural self cleaning systems that can get rid of any material on their own.
At some parts of the ocean, new crust are being formed. In some other part, new crustal materials are added.
When organisms in the ocean die, they decay to produce some carbon compounds which goes back to the ocean and atmosphere. Their skeletal parts goes to the bottom of the ocean where it compacts with sediments to form new sedimentary rock sequences.
When wastes from land are brought into the ocean, they can be broken down on the long run.
The ocean is self cleaning and it is an effective system as such.
