Question

(TCO 1) Ecological dialogue can best be summarized as:

A) what we believe about the environment depends on what we see and feel.

B) what we see and feel about the environment depends on what we believe.

C) Both A and B are correct.

D) Neither A nor B is correct.

(TCO 2) Which of the following is the major cause of species extinction?

D) Interrupted reproduction

(TCO 3) The 1995 Nobel Prize in Chemistry was awarded to three scientists whose work led to discovery of the causes for the thinning of the earth's atmosphere by chlorofluorocarbons (CFCs). Which of the following was NOT one of these scientists?

A) Habitat loss

Explanation / Answer

1) Ecological dialogue can best be summarized as:

A) what we believe about the environment depends on what we see and feel.

B) what we see and feel about the environment depends on what we believe.

C) Both A and B are correct.

D) Neither A nor B is correct.

In order to define an Ecological dialogue, what we believe about the environment is significant. This could depend upon what we see around and what we feel about the same. However, that is not enough. One needs to walk a step ahead by comprehending the ‘see and feel’ ideas about the environment based on the common beliefs that one posses because it is the belief about something that in turn helps in defining a subject more efficiently. Hence both the options A and B are correct in this regard.

Question 2. Which of the following is the major cause of species extinction? (Points : 5)
Habitat loss
Pollution
Genetic engineering
Interrupted reproduction

It is because of the Habitat loss of the species mainly that these species do not find suitable ambience to live in. Being compelled to live in some other habitat that is not their natural habitat, has resulted into difficulties in survival of such species. Hence Habitat loss is a major cause of species extinction.

Question 3. The 1995 Nobel Prize in Chemistry was awarded to three scientists whose work led to discovery of the causes for the thinning of the earth's atmosphere by chlorofluorocarbons (CFCs).
Which of the following was NOT one of these scientists? (Points : 5)
Mario Molina
Paul Crutzen
Sherwood Rowland
Aldo Leopold

Although an ecologist, Aldo Leopold in fact, did not live during the era when the Nobel Prize in Chemistry was awarded in 1995. He passed away in the year 1949, which was more than half a century before the work led to discovery of the causes for the thinning of the earth's atmosphere by chlorofluorocarbons (CFCs).
