Question

1. which of the following is a similarity shared by all four conservation profiles? * 100 points a. each faces challenges from invasive species. b. each provides essential ecosystem services to humans. c. each is located in a desert climate. d. each has already fully recovered from human impacts.

Explanation:

• Option A: Not all conservation profiles may face invasive species challenges (depends on the specific profiles, e.g., some might be in non - invasive - species - prone areas).
• Option B: Ecosystem services (like water purification, carbon sequestration, food provision, etc.) are essential functions that most, if not all, conservation - worthy ecosystems provide to humans. This is a fundamental aspect of why we conserve ecosystems.
• Option C: Conservation profiles can be in various climates (tropical, temperate, arctic, etc.), not just desert.
• Option D: Most conservation profiles are still recovering from human impacts or are at risk, and few have "fully recovered".

Answer:

B. Each provides essential ecosystem services to humans.
