Question 1 of 5
1. Question
Consider the following statements regarding snowflake coral
- It is a keystone species of marine ecosystem.
- It is found only in Gulf of Kutch.
Which of the above statements is/are correct?
Correct
Solution: d)
- Colonies of snowflake coral (Carijoa riisei), an invasive species was documented off the coast of Thiruvananthapuram and Kanyakumari. It could pose a serious threat to the marine ecology of the region.
- The snowflake coral is known to inhabit reefs and underwater structures such as shipwrecks and piers, attaching itself to metal, concrete and even plastic. It is considered an invasive species because of its capacity to dominate space and crowd out other marine organisms.

Question 2 of 5
2. Question
Due to some reasons, if there is a huge fall in the population of species of butterflies, what could be its likely consequence/consequences?
- Pollination of some plants could be adversely affected.
- There could be a drastic increase in the fungal infections of some cultivated plants.
- It could lead to a fall in the population of some species of wasps, spiders and birds.
Select the correct answer code:
Correct
Solution: c)
Bees and butterflies play a vital role in the pollination of plants and the production of crops by transporting pollen grains from one place to another.
Statement 2 is an absurd statement.
These are some of the common predators of butterflies: wasps, ants, parasitic flies, birds, snakes, toads, rats etc. The decline in butterfly population would therefore adversely affect the food chain.

Question 3 of 5
3. Question
What do you understand by an indicator species?
Correct
Solution: a)
It provides information on the overall condition of the ecosystem and of other species in that ecosystem. It reflects the quality and changes in environmental conditions as well as aspects of community composition.
River otters (Lontra canadensis) can be an indicator species of clean rivers. Or presence of too much algae can be the indication of toxicity in a marine ecosystem.

Question 4 of 5
4. Question
What is a “Biotope”?
Correct
Solution: b)
Biotope is an area that is uniform in environmental conditions and in its distribution of animal and plant life. It is often used interchangeably with the world habitat.
A biotope is generally not considered to be a large-scale phenomenon. For example, a biotope might be a neighbouring park, a back garden, even potted plants or a fish tank on a porch.
In other words, the biotope is not a macroscopic but a microscopic approach to preserving the ecosystem and biological diversity.
Phenotype is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

5. Question
What do you understand by Ecological footprint?
Correct
Solution: c)
As per the Millennium Eco Assessment it is an index of the area of productive land and aquatic ecosystems required to produce the resources used and to assimilate the wastes produced by a defined population at a specified material standard of living, wherever on Earth that land may be located.
Ecological footprint analysis is widely used around the Earth in support of sustainability assessments.
It can be used to measure and manage the use of resources throughout the economy and explore the sustainability of individual lifestyles, goods and services, organizations, industry sectors, neighborhoods, cities, regions and nations.
