Which of the following hypotheses account for the relationship of biodiversity to ecosystem functioning?

Correct option is C

The correct answer is (c) Redundancy hypothesis. This hypothesis suggests that biodiversity is essential to ecosystem functioning, but beyond a certain point, many species become functionally redundant. It implies that a high level of species richness provides resilience, ensuring that ecosystem functions are maintained even if some species are lost.
Explanation of Other Options:
· (a) Climate Stability Hypothesis: Suggests that stable climates promote higher biodiversity but does not directly relate biodiversity to ecosystem functioning.
· (b) Intermediate Disturbance Hypothesis: Proposes that biodiversity is highest at intermediate levels of disturbance. It focuses on species diversity patterns rather than ecosystem functioning.
· (d) Spatial Heterogeneity Hypothesis: States that more heterogeneous environments support higher biodiversity. It addresses biodiversity patterns rather than how biodiversity influences ecosystem processes.
Information Booster: 1. Redundancy Hypothesis:
· Suggests that ecosystem function increases with biodiversity but plateaus once functional redundancy is reached.
· Provides resilience to ecosystems, as different species can perform similar roles.
2. Climate Stability Hypothesis:
· Proposes that regions with stable climates support greater species diversity due to consistent environmental conditions.
3. Intermediate Disturbance Hypothesis:
· Predicts maximum biodiversity at intermediate levels of disturbance, balancing competition and colonization.
4. Spatial Heterogeneity Hypothesis:
· Suggests that diverse habitats and microenvironments support greater species diversity.
Additional Knowledge: · Biodiversity and Ecosystem Functioning (BEF): Higher biodiversity often leads to increased productivity, stability, and resilience in ecosystems.
· Functional Redundancy: The presence of multiple species that can perform similar ecological roles, maintaining ecosystem function if some species are lost.
· Resilience: The ability of an ecosystem to recover from disturbances due to the diversity of functions provided by different species.
