for each population pyramid below:

1. state which country it represents (germany, united kingdom, china, india, sierra leone)
2. use the following statements to describe the population pyramids (each statement can be used more than once).

high birth rates
low birth rates
high death rates
low death rates
top heavy
bottom heavy
bulging middle

1. describe the economically active, elderly dependents and young dependents sections of the pyramids.

Explanation:

1. Without seeing the specific shapes of the population pyramids clearly, general knowledge about population pyramids of these countries can be used. Germany and the United Kingdom often have low - birth - rate and low - death - rate pyramids which can be top - heavy or have a bulging middle due to an aging population. China has been experiencing a decline in birth rates and has a more balanced to somewhat top - heavy pyramid in recent years. India has high birth rates and is typically bottom - heavy. Sierra Leone may have high birth rates and relatively high death rates and is usually bottom - heavy.
2. High birth rates result in a wider base of the pyramid (bottom - heavy), low birth rates can lead to a more narrow base. High death rates can affect the overall shape and size of the pyramid, especially in the younger age groups, while low death rates contribute to a more even distribution or a top - heavy shape as the elderly population grows. A top - heavy pyramid has more elderly people, a bottom - heavy has more young people, and a bulging middle indicates a large working - age population.
3. The economically active section is typically the middle - aged group (usually 15 - 64 years old). Elderly dependents are the older age groups (65+), and young dependents are the younger age groups (0 - 14 years old). The size and shape of these sections in the pyramid can be described based on the width of the corresponding bars in the pyramid.

Since the specific population pyramids are not fully described in text and only a picture reference is given without clear visual details in the text, a detailed answer for each pyramid cannot be provided. But in general:
For India and Sierra Leone, we would expect high birth rates and bottom - heavy pyramids with a large young dependents section and a relatively smaller economically active section compared to the young population initially. For Germany and the United Kingdom, low birth rates, low death rates, and possibly top - heavy or bulging middle pyramids with a relatively large elderly dependents section. China may have low birth rates, low death rates, and a more balanced to top - heavy pyramid with a significant economically active section currently but a growing elderly dependents section.

Answer:

Without clear visual details of each pyramid, specific answers for which country each represents and detailed descriptions cannot be accurately given. But in general:

• For high birth rates: India, Sierra Leone are likely candidates.
• For low birth rates: Germany, United Kingdom, China.
• For high death rates: Sierra Leone may be a candidate.
• For low death rates: Germany, United Kingdom, China.
• For top - heavy: Germany, United Kingdom, China.
• For bottom - heavy: India, Sierra Leone.
• For bulging middle: China, United Kingdom, Germany may have this in some cases.
• Economically active: Middle - aged sections of the pyramids.
• Elderly dependents: Older age groups at the top of the pyramids.
• Young dependents: Younger age groups at the bottom of the pyramids.
