Question

if all plant and algae cells suddenly lost their chloroplasts, what would be the most significant consequence for the ecosystem? the production of glucose would stop, limiting the matter available to the ecosystem. the amount of water in the ecosystem would increase. the chloroplasts would start producing their own carbon dioxide. the plant would adapt to use oxygen instead of carbon dioxide.

Explanation:

Plants and algae rely on chloroplasts for photosynthesis, which produces glucose. Without chloroplasts, glucose production would stop, limiting available matter in the ecosystem.

Answer:

The production of glucose would stop, limiting the matter available to the ecosystem.
