Which of the following statements is correct?a)Air is a living thing b...
Explanation:
Living and non-living things:
Living things are organisms that have the characteristics of life, such as growth, reproduction, response to stimuli, metabolism, and the ability to adapt to their environment. Non-living things, on the other hand, do not possess these characteristics and are incapable of growth, reproduction, or any other life processes.
The characteristics of living things:
1. Growth: Living things have the ability to grow and increase in size over time.
2. Reproduction: Living things can produce offspring of their own kind through sexual or asexual reproduction.
3. Response to stimuli: Living things can respond to external stimuli, such as light, heat, or sound.
4. Metabolism: Living things have the ability to obtain and utilize energy through metabolic processes.
5. Adaptation: Living things can adapt to changes in their environment to ensure their survival.
Analysis of the given statements:
Let's analyze each statement to determine if it is correct or incorrect:
a) Air is a living thing because it can move.
- This statement is incorrect. Movement alone does not make something a living thing. Air is a mixture of gases and does not possess the characteristics of living things. It does not grow, reproduce, respond to stimuli, or have metabolism.
b) Banyan tree is a non-living thing because it cannot move.
- This statement is incorrect. Banyan tree is a living thing because it possesses all the characteristics of living things. It can grow, reproduce, respond to stimuli, and has metabolism.
c) A balloon is a living thing because it grows in size when air is pumped into it.
- This statement is incorrect. A balloon is a non-living thing. It does not possess the characteristics of living things. The expansion of a balloon when air is pumped into it is due to the physical properties of air, not the growth of a living organism.
d) A wheat grain is a living thing because it can grow into a new plant.
- This statement is correct. A wheat grain is a living thing. It possesses the characteristics of living things. When a wheat grain is planted in suitable conditions, it can germinate and grow into a new wheat plant, demonstrating the ability to reproduce and grow.
Conclusion:
The correct statement is option 'D'. A wheat grain is a living thing because it can grow into a new plant.
