Which of the following is an element of custodial management? Introducing new species into an ecosystem
Being able to control an animal’s environment
Using forest management principles in woodlands
Repairing any part of the environment destroyed by a natural disaster

B. Being able to control an animal’s environment.

Explanation:

An ecosystem can be defined as the natural living habitats of both living and non-living organisms. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.

Custodial management can be defined as a wildlife management technique that is typically focused on protecting or preventing any harm to the environment of living organisms such as plants and animals.

Basically, the main purpose of a custodial management is to minimize or mitigate any external influence on the living organisms and their natural habitat such as in wildlife. Thus, there are no interference by anyone on the animals in their natural habitats or wildlife.

Hence, an element of custodial management is being able to control an animal’s environment.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
