The threats that are associated with the many species of amphibians in the world and also determine the reason due to which an individual should neglect hastening the actual extinction of any type of species of amphibian using its activities.

Answer to Problem 1CR
Many species of the amphibians are declining at an alarming rate, and a major fraction of these species have already vanished. An individual should be concerned about the extinction of amphibians because the majority of amphibians are of great importance.
Explanation of Solution
There is a great threat to the many species of the amphibians. The frogs, salamanders, and toads are at great risk. The overall increase in the use of insecticides and chemical pollutants are responsible for the overall extinction of the species of the amphibians.
The individual should be concerned about the extinction of amphibians because of some reasons. Those reasons are described as follows:
(i) The majority of amphibians are sensitive and act as the potent biological indicators of various types of changes in the environment.
(ii) The majority of adult amphibians play an important role in the biological communities of the ecosystem.
(iii) Various amphibians act as the potent storehouse of products of pharmaceutical companies. For example- secretion of several amphibians act as the major ingredients of the various pain killers and antibiotics.

Do particles in deep-water waves trace out circular or elliptical paths? 2. Near the shore in shallow water, do water particles trace out circular or elliptical 3. In shallow water, are water particles in the wave crest ahead of or behind those at the bottom of the wave? 4. As waves approach the shore, do their heights increase or decrease? Do wavelengths become longer or shorter? 5. In the surf zone, is the water in the crest of a wave falling forward or standing still? 6.
