Question

how can an increase in biodiversity lead to an increase in ecosystem stability?
a. a more biodiverse ecosystem is not subject to change.
b. a more biodiverse ecosystem has a higher chance of adapting to species changes.
c. a more biodiverse ecosystem has fewer species types to balance.
d. a more biodiverse ecosystem is subject to fewer natural disasters.
please select the best answer from the choices provided
a
b
c
d

Explanation:

• Option a: No ecosystem is completely un - changing. Ecosystems are dynamic and subject to various internal and external changes.
• Option b: A more biodiverse ecosystem has a greater variety of species. If one species is affected (e.g., by disease, predation pressure, or environmental change), other species can often take on the ecological roles (such as pollination, decomposition, or energy transfer) that the affected species performed. This ability to adapt to species - level changes contributes to ecosystem stability.
• Option c: A more biodiverse ecosystem has more species types. The balance in a biodiverse ecosystem is maintained through complex interactions (e.g., predator - prey relationships, symbiotic relationships) among these many species.
• Option d: Biodiversity does not directly reduce the occurrence of natural disasters. Natural disasters (such as floods, wildfires, earthquakes) are mainly driven by physical and geological processes, not by the level of biodiversity in an ecosystem.

Answer:

B. A more biodiverse ecosystem has a higher chance of adapting to species changes.
