Reproductive isolation between segments of a single
population is termed

1Sympatry
2Allopatry
3Population divergence
4Disruptive divergence

2.

(c) Montreal protocol – Global warming
(d) Ramsar convention – Ground water pollution

(b) Kyotoprotocol is an international conference held in
Kyoto, Japan obtained commitments from different
countries for reducing overall greenhouse gas emissions
by 2008-2012.

3.

Which of the following statements is true regarding
individuals of same species

1They are interbreeding
2They live in same niche
3They live in different niche
4They live in different habitat

(a) Uniform interbreeding population or group of
individuals which freely interbreed among themselves,
constitute a species.

4.

Which one of the following correctly represents an organism
and its ecological niche

1Vallisneria and pond
2Desert locust (Scistocerca) and desert
3Plant lice (aphids) and leaf
4Vultures and dense forest

5.

Niche overlap indicates

1Sharing of one or more resources between the two species
2Mutualism between two species
3Active cooperation between two species
4Two different parasites on the same host

6.

What is a keystone species

1A rare species that has minimal impact on the biomass and on other species in the community
2A dominant species that constitutes a large proportion of the biomass and which affects many other species
3A species which makes up only a small proportion of the total biomass of a communities, yet has a huge impact on the communities organization and survival
4A common species that has plenty of biomass, yet has a fairly low impact on the communities organization

7.

Two plants can be conclusively said to belong to the same
species if they

1Can reproduce freely with each other and form seeds
2Have more than 90 percent similar genes
3Look similar and possess identical secondary metabolites
4Have same number of chromosomes

8.

The study of inter-relationship between living organisms and
their environment is called

1Ecosystem
2Phytogeography
3Ecology
4Phytosociology

(c) The term ecology is derived from two greek words,
namely Oikos and Logos. Oikos means ‘home’ or
‘habitation’ or a ‘place to live in’. Logos means ‘study’
or ‘discourse’. Hence literally speaking, ecology is the
study of organisms at home.

9.

Term ‘ecology’ was proposed by

1William
2Odum
3Reiter
4Daubenmier

(c) The term ecology is believed to have been coined by
Ernst Haeckel (1869) though its first authentic use was
made by Reiter (1885).
