Choose the correct statements.
1 A, B, C
2 B, C, D
3 A, C, D
4 A, B, D
Explanation:
Ecosystems also exert direct physical influence that help to moderate regional and local weather. - Decline in pollinator activity could mean rising cost of pollination dependent fruits and vegetables. - Robert Constanza and his colleagues have tried to put price tag on nature's life support services. All the above statements are true while the total annual account of wet organic matter of the forest can be estimated with the annual net productivity amount of standing forest. Statement (A) is wrong.

In 'rivet popper hypothesis', Paul Ehrlich compared the rivets in an airplane to
1 Ecosystem
2 General within a family
3 Species within a genus
4 Genetic diversity
Explanation:
The rivet popper hypothesis proposed by Paul Ehrlich compares an ecosystem to an aeroplane, the species to the rivets and the keystone species to the wing rivets and he proposed that if the rivets are taken out gradually then ultimately the plane would also crash too.
