2. INDICATOR SPECIES
An indicator species is an organism whose presence,
absence or abundance reflects a specific
environmental condition. Indicator species can signal a
change in the biological condition of a ecosystem, and
thus may be used as a proxy to diagnose the health of
an ecosystem.
Phytoremediation (technologies that use living plants to
clean up soil, air, and water contaminated with hazardous
contaminants.)

3. A species having impacts on many others,
often far beyond what might have been
expected from a consideration of their
biomass or abundance.
Umbrella species

5. Popular charismatic species that
serve as symbols and rallying
points to stimulate conservation
awareness and action A species
that has become a symbol and
leading element of an entire
conservation campaign
Flagship species

7. RUDERAL SPECIES
ARE THOSE WHICH
ARE FOUND IN THE
ENVIRONMENT WITH
?
Low disturbance, high competition
High disturbance, low competition
Low disturbance, low competition
High disturbance, high competition

8. A species having impact on many other, often for beyond what might have
been expected from a consideration of their biomass or abundance.
They are top predators or engineer species
• Disproportional to it's abundance
• Minimum in number but maximum effect
• They are usually to Top predators or engineers
Ecosystem effect ∝ 1

9. The elephant destroys all
the herbs that are to be
grown in the tree in the
future

keystone

11. Which of the
following is statement
is incorrect about the
Keystone species ?
species other than consumer can
be a keystone species
Keystone species has influence
on a community proportionate to
its abundant
removing a Keystone species can
reduce species richness of a
community
removing Keystone species can
affect successive trophic level
causing a trophic cascade
