Question

1. which of the following is an example of habitat restoration mentioned in the content? a. expanding industrial zones b. building new urban areas c. restoring wetlands in the florida everglades d. constructing dams on rivers 11. which of the following is not a characteristic of a keystone species? a. it influences the types and numbers of other species b. its removal can lead to significant changes in the ecosystem c. it plays a critical role in maintaining ecosystem structure d. it has a large population 12. which of the following is a characteristic of an s - shaped curve on a population growth graph? a. growth rate slows as population approaches carrying capacity b. constant growth rate throughout time c. population crashes after reaching maximum size d. population grows without bounds

Explanation:

1. Habitat restoration aims to repair damaged ecosystems. Wetland - restoration in the Florida Everglades is an example of habitat restoration. Expanding industrial zones, building new urban areas, and constructing dams usually cause habitat destruction rather than restoration.
2. A keystone species has a large impact on its ecosystem relative to its abundance, influencing other species and maintaining ecosystem structure. Its removal can cause significant changes. It doesn't necessarily have a large population.
3. An S - shaped (logistic) curve in population growth shows that the growth rate slows as the population approaches the carrying capacity of the environment. A constant growth rate is characteristic of exponential growth, population crashes are not typical of S - shaped curves, and unbounded growth is also exponential.

Answer:

1. C. Restoring wetlands in the Florida Everglades
2. D. It has a large population
3. A. Growth rate slows as population approaches carrying capacity
