Organisms that are least likely to experience extinction over the long term are most likely to be found in:

1.	areas inhabited by humans	2.	very stable habitats
3.	desert	4.	savanna

Consider the two statements:
I. Ex situ conservation is rarely enough to save a species from extinction.
II. It is to be used as a last resort, or as a supplement to in situ conservation

1. Both I and II are correct and II explains I.
2. Both I and II are correct but II does not explain I.
3. Both I and II are incorrect.
4. Only I is correct.

Consider the two statements:

I. Biological control by an introduced control can affect biodiversity.
II. An introduced control does not always target only the intended pest species; it can also target native species.

1. Both I and II are correct and II explains I.
2. Both I and II are correct but II does not explain I.
3. I is correct but II is incorrect.
4. Both I and II are incorrect.

Exploring molecular, genetic and species-level diversity for products of economic importance is called as:

We all know that water hyacinth is an invasive plant that has caused havoc in many water bodies in our country. But it has some usefulness as well. This includes:
I. Substrate for biogas production
II. Bio cleaning of industrial waters
III. Source of effective antipyretic

The most effective biologic control of insects is achieved by:

Plants are an important source of medicines for human use. Identify the incorrectly matched pair:

Overexploitation is one of the “evil quartet” that increases the risk of extinction mainly for the:
1. animals that feed on a lower trophic level
2. large animals with low intrinsic reproductive rates
3. aquatic animals
4. terrestrial organisms
