Glucose or sugar are produced during photosynthesis.
Answer: Option B) . a decrease in the amount of oxygen dissolved in
the pond
Explanation:
Anaerobic bacteria are able to survive in the absence of oxygen while aerobic bacteria survive only in the presence of abundant oxygen.
Hence, while reduced levels of dissolved oxygen in the pond decrease the amount of aerobic bacteria like Bacillus; anaerobic bacteria like Actinomyces flourish since they survive on organic substances like methane, cellulose instead.
Human activities such as Smog and Greenhouse gas can weaken the Earth's atmosphere allowing the suns rays to be more powerful when passing through the Atmosphere.
