3) Salim Ali’s fruit bat
4) Lion tailed Macaque

a. Only 1 and 2
b. Only 1, 2 and 3
c. Only 2, 3, 4 and 5
d. All of the above
Answer  Explanation 

ANSWER: Only 1, 2 and 3

Explanation:
2, 4 and 5 are endangered species.
2)   Which of the following statement/s is/are correct?

1) Neutralism describes the relationship between two species which help each other.
2) Symbiosis is type of Neutralism.

a. Only 1
b. Only 2
c. Both 1 and 2
d. None of the above
Answer  Explanation 

ANSWER: None of the above

Explanation:
Neutralism describes the relationship between two species which do interact but do not affect each other. Mutualism is a close association between two species in which both the species benefit. However, some mutualisms are so intimate that the interacting species can no longer live without each other as they depend totally on each other to survive. Such close associations are called symbiosis. Familiar example of symbiosis is seen in pollination of flowers where flowering plants are cross pollinated by the bees which benefit by getting nectar from the plants and both cannot survive without the other.
3)   Which of the following statement/s is/are correct regarding human modified ecosystems?

1) Even if they are Human modified ecosystems, they depend on solar energy.
2) Human modified Ecosystems are complex and unstable.

a. Only 1
b. Only 2
c. Both 1 and 2
d. None of the above
Answer  Explanation 

ANSWER: None of the above

Explanation:
Human modified ecosystems may or may not depend on solar energy e.g. in an industry energy is provided in the form of fossil fuel or electricity or both. They are highly simplified, have low species diversity and are highly unstable. Some examples of human modified ecosystems are: Agro-ecosystems, Plantation forests, Urban ecosystems, Rural ecosystems, Aquaculture, Industrial areas, Laboratory cultures, etc.
