Read the passage and answer the following questions:
Six pairs of bald vulture were released into the wild in Germany. Four of the pairs of birds successfully nested and raised young. Two of the pairs nested near an industrial complex that released waste products (PCBs) into a nearby lake. These birds laid eggs, but the embryos failed to develop.
Which of the following is the least likely reason for the failure of the embryos to develop?

  1. Mutations in the embryos halted their development.

  2. The adult birds failed to exhibit proper nesting behavior and did not care for the eggs.

  3. The contaminated lake water that the birds consumed affected the development of their young.

  4. The sperm of the males were affected by the PCBs in such a way that they were unable to fertilize the eggs.

  5. Germany is not a good location for bald eagles to mate and reproduce.
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

The release of waste products into the nearby lake caused various problems which led to the failure of the embryo development. This can happen because of the following reasons:

  • The chemicals released from the factory caused some mutations in the embryos which led to the failure in development.
  • The birds might not have taken care of the eggs and they might have failed to exhibit proper nesting behavior.
  • The chemicals in the contaminated lake water might have affected the development of the birds.
  • The chemicals from the lake might have affected the sperms of the males and so they were unable to fertilize the eggs. Thus, the correct answer is option E.

For clean environment, which one is not essential?

  1. Producer

  2. Polluter

  3. Consumer

  4. Decomposer
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The producer is required initially for the availability of organic food. The consumer will consume the organic food prepared by the producer and will also make an equilibrium in the environment by being a part of the nutrient cycle. A decomposer will breakdown the dead organic from the dead bodies of producer and consumer. So, these are required in a functional ecosystem. The presence of polluter is undesirable as it would distort the environment, making it difficult for the biotic and abiotic components to keep their sustenance.

Hence, the correct answer is 'Polluter'.
