Assertion: Green plants of the ecosystem are the transducers.
Reason: Producers trap the radiant energy of the sun and change it into chemical energy.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct but reason is not the correct explanation of assertion.
Assertion is true but Reason is false.
Assertion is false but Reason is true.
(1)
Green plants of the ecosystem are the transducers because producers trap the radiant energy of the sun and change it into chemical energy. Thus, both assertion and reason are correct and reason is the correct explanation of the assertion.
Assertion: Energy available at each trophic level gets diminished progressively.
Reason: Little usable energy remains after four trophic levels.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct but reason is not the correct explanation of assertion.
Assertion is true but Reason is false.
Assertion is false but Reason is true.
(3)
The energy available at each trophic level gets diminished progressively due to loss of energy at each level. The usable energy available at each trophic level gets diminished progressively due to loss of energy at each level. Thus, assertion is true but reason is false.
Assertion: The flow of energy is unidirectional.
Reason: Energy as it progresses through the various trophic levels is no longer available to the previous level
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct but reason is not the correct explanation of assertion.
Assertion is true but Reason is false.
Assertion is false but Reason is true.

The flow of energy is unidirectional. The energy that is captured by the autotrophs does not revert to the solar input and the energy which passes to the herbivores does not come back to autotrophs. As it moves progressively through the various trophic levels it is no longer available to the previous level. Moreover, the energy available at each trophic level gets diminished progressively due to loss of energy at each level. Thus, both assertion and reason are correct and reason is the correct explanation of the assertion.
Assertion: Chemicals and toxins accumulate more and more as we move up the food chain.
Reason: Anything that gets into biological tissue, that is not normally there, has the potential to accumulate and magnify.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct but reason is not the correct explanation of assertion.
Assertion is true but Reason is false.
Assertion is false but Reason is true.

Biomagnification is the increase in concentration of toxins up the food chain. Chemicals and toxins accumulate more and more as we move up the food chain, because they do not get broken down in the body. Anything that gets into biological tissue, that is not normally there, has the potential to accumulate and magnify as it moves up the food chain. Thus, both assertion and reason are correct and reason is the correct explanation of the assertion.
Assertion: Arctic’s ozone depletion tends to be milder and short lived than the Antarctic’s.
Reason: CFCs, Frigid temperatures and sunlight are not present at the Arctic at the same time.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct but reason is not the correct explanation of assertion.
Assertion is true but Reason is false.
Assertion is false but Reason is true.

It is necessary to have all three at the same time for ozone layer to deplete. Thus, both assertion and reason are true and reason is the correct explanation of the assertion.
Assertion: Plastics are non-biodegradable.
Reason: Enzymes cannot degrade plastics.
Both assertion and reason are correct and reason is the correct explanation of assertion.
Both assertion and reason are correct but reason is not the correct explanation of assertion.
Assertion is true but Reason is false.
Assertion is false but Reason is true.
(1)
Substances which cannot be decomposed by the action of microorganisms are known as non-biodegradable substances. Microorganisms release enzymes which decompose the materials but these enzymes are specific in their action that is why enzymes cannot decompose all the materials. Thus, both assertion and reason are correct and reason is the correct explanation of the assertion.
