Answer:
D. atmospheric aerosols.
Explanation:
<em>Atmospheric aerosols are tiny particles that float in the air. These particles could be liquid or solid and are usually suspended primarily by direct emission into the atmosphere or secondarily by condensation process. </em>
Atmospheric aerosols have numerous effects on the biotic and abiotic factors of the environment. They alter air quality and impact human health in some cases, they can reduce atmospheric visibility, and they also reduce the amount of radiation that reaches the earth by scattering or reflecting some of the radiations from the sun back into space, leading to cooling of the atmosphere.
Answer:
Yes
Explanation:
In the past climate change models were not accurate as they mostly understated the problems which resulted in more damages caused due to inaccurate preparations. However due to new technological innovations, there has been availability and improvement in the tools such as satellites.
This has led to an increase in the accuracy of the climate change models and subsequent planning of costal city infrastructures.
Answer:
(A) While not important in the diet of raccoons or striped skunks, ground squirrels are a significant source of food for other waterfowl-nest predators.
Explanation:
According to the passage, some predators of waterfowl nests prey opportunistically on songbird nests. Therefore, some wildlife management procedures directed at waterfowl, such as habitat enhancement or restoration, may also benefit songbirds. However, some procedures such as predator control may not always lead to benefits for the songbirds. For example, some predators of waterfowl nests such as raccoon and striped skunks are not predators of small mammals such as mice and ground squirrels who themselves are predators of songbird nests. So removing the striped skunk and raccoons from the habitat of the waterfowl and songbird nests, may not bring any benefit whatsoever to the songbirds. However, many other predators of waterfowl nests are also predators of squirrels and mice.
