Answer: C. Producer populations will decrease, causing a decrease in consumer populations.

Explanation:

According to the situation, the volcanic ash will mask the light energy from sun. The sunlight is the main requirement for the producers to synthesize their own food by the process of photosynthesis. The population of plants and other autotrophs will be affected by this. The other organisms in the ecosystem will be affected as decline in the population of producers will result in decline in the population of consumers due to lack of food.

sergiy2304 [10]

Answer:

protected; increase

Explanation:

Ozone is composed of trioxygen which is highly reactive gas compared to dioxygen. Ozone layer is present in stratosphere and troposphere and protect the humans from ultraviolet radiations but it may be toxic if inhaled. Ozone can be broken down into molecular oxygen by chlorine and bromine atoms.

A hole was discovered in ozone layer in 1982 and scientist believed that it could be dangerous for human health. The compounds involved in depletion of ozone are mainly Chlorofluorocarbons (CFS) and (HFCS). Then a global agreement was signed in 1987 which leads to prohibition of use of all chemicals that are involved in depletion of ozone layer. The problem of ozone depletion is solved by the agreement and ozone hole started to recover it from 2000.

But recent reports showed that the alternative chemicals used to protect the depletion of ozone layer began to trap the heat inside the earth like greenhouse effect. Now scientists are in search of chemical that can prevent both ozone depletion as well as global warming.
