Summary Introduction

To complete: The map which organizes some of the key concepts of conservation biology.

Introduction:

The key concepts and themes of conservation biology include:

Concept 1:“Prevention of the extinction of the endangered species”.

Concept 2: “Projects to restore and conserve ecology”.

Concept 3: “Bioremediation”.

Concept 4:“Formation of zoned reserves for the preservation of the species of plants and animals”.

Answer to Problem 1CC

Pictorial representation:

Fig no.1 shows the completed map of the key concepts of conservation biology.

Fig.1: Key concepts of conservation biology.

Explanation of Solution

(a)

Correct answer: Species at risk of extinction.

Explanation:

The species of various plants and animals are preserved in various ecological habitats to prevent them from getting endangered and extinct. The branch of biology used to study this is called as “conservation biology”. Hence the correct answer is species at risk of extinction.

(b)

Correct answer: Restoration ecology.

Explanation:

The destruction of the habitat of animal and plant species due to pollution, hunting of animals, natural calamities like floods, afforestation or the cutting of the forests and over-grazing by animals causes the inability to breed. The branch of biology, which includes the reestablishment of the natural resources, habitat and ecosystems so that the species can survive, is called “restoration ecology”. Hence, the correct answer is restoration ecology.

(c)

Correct answer: Bioremediation.

Explanation:

The process of regeneration of the natural habitat, ecosystem, and preservation of the fertility of soil by planting trees leads to the preservation of the climate and habitat of the plants and animals. The study of this field of biology is called as “Bioremediation”. Hence, the correct answer is bioremediation.

(d)

Correct answer: Zoned reserves.

Explanation:

The preservation of the species of plantsand animals is done in the zoned reserves, where they are preserved by providing regular food and shelter. Hence, the correct answer is zoned reserves.
