Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.


Manja, or the glass-coated string used for flying kites, not only poses threat to humans, animals and birds but also to trees. A study by the country's oldest botanical garden has revealed that it poses a great threat to trees. But how can a snapped string struck in a tree kill the tree? Apparently, it does so by allying with the creepers in the garden.


A research paper by three scientists of the Acharya Jagdish Chandra Bose Indian Botanic Garden, located in West Bengal's Howrah district, illustrates in detail how the manja, in collusion with climbers, does the damage. "The abandoned, torn kite strings act as an excellent primary supporting platform for the tender climbers, giving easy passage to reach the top of the trees. Lateral branches from the top of the climber and other accessory branches from the ground reaches the top taking support of the first climber, completely covers the treetop, thus inhibiting the penetration of sunlight," says the research paper.

A) By blocking its access to sunlight B) By wrapping its tentacles around its branches
C) By sucking away the nutrients D) By secreting toxic chemicals

Q:

Statement I :

Bioaccumulation is a process of progressive accumulation of heavy metals and pesticides in an organism.

Statement II :

Large fishes of the pond are found to have higher concentration of pesticides than planktons of the same pond.

 

A) Both the statements are individually true and Statement II is the correct explanation of Statement I B) Both the statements are individually true but Statement II is not the correct explanation of Statement I
C) Statement I is true but Statement II is false D) Statement I is false but Statement II is true
 
Answer & Explanation Answer: B) Both the statements are individually true but Statement II is not the correct explanation of Statement I

Explanation:

Bioaccumulation is defined as the increase in concentration of a substance(s) in an organism or a part of that organism.

The affected organism has a higher concentration of the substance than the concentration in the organism's surrounding environment.

For the second statement: Microorganisms eat pesticide infected things. Invertebrates eat hundreds of the microorganisms and plants infected with the pesticides, accumulating a pretty large amount of the toxin in them.

The invertebrates are generally then eaten by larger invertebrates or amphibians, which ingest hundreds of similar organisms, accumulating an even higher concentration of toxins in their bodies. Then the fish eat hundreds of these organisms, accumulating the highest concentration of toxins in themselves.
