Directions: In the following questions, a statement of assertion (A) ...
Assertion: Food chain is responsible for the entry of harmful chemicals in our bodies.
Reason: The length and complexity of food chains vary greatly.
Explanation:
The given assertion states that the food chain is responsible for the entry of harmful chemicals in our bodies. The reason provided is that the length and complexity of food chains vary greatly.
Understanding the Assertion:
The food chain refers to the transfer of energy and nutrients from one organism to another through the consumption of food. It is a linear sequence of organisms where each organism serves as both a consumer and a food source. In this process, harmful chemicals can enter our bodies through the consumption of contaminated food.
Understanding the Reason:
The reason given states that the length and complexity of food chains vary greatly. This means that food chains can be short and simple, involving only a few organisms, or they can be long and complex, involving multiple trophic levels and interactions between different organisms.
Explaining the Relationship:
The reason provided does not directly explain why the food chain is responsible for the entry of harmful chemicals in our bodies. However, it does highlight an important aspect of food chains - their varying lengths and complexities. This variation in food chains can influence the accumulation and transfer of harmful chemicals through different trophic levels.
Conclusion:
Both the assertion and reason are true. The food chain is responsible for the entry of harmful chemicals in our bodies, and the length and complexity of food chains vary greatly. However, the reason does not directly explain the assertion and therefore, it is not the correct explanation of the assertion.
