Question

which of the following will most likely occur from the modification of natural ecosystems by humans?
a. increased stability in the ecosystem
b. increased biodiversity
c. decreased carbon dioxide emissions
d. decreased biodiversity

Explanation:

Human modification of natural ecosystems (e.g., deforestation, urbanization, pollution) typically reduces species richness and ecological balance. This loss of biodiversity weakens ecosystem resilience, making stability decrease, not increase. Carbon dioxide emissions often rise due to such modifications, but the most direct and common ecological impact among the options is decreased biodiversity.

Answer:

D. decreased biodiversity
