What is the primary factor that determines the resilience of a temperate ecosystem?
-
Species diversity
-
Climate stability
-
Soil fertility
-
Water availability

Which of the following is an example of an adaptation that helps temperate ecosystems recover from disturbances?
-
Increased seed production
-
Rapid growth
-
Enhanced nutrient cycling
-
All of the above
D
Correct answer
Explanation
Increased seed production, rapid growth, and enhanced nutrient cycling are all examples of adaptations that help temperate ecosystems recover from disturbances.
