The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that epiphytes use trees only for attachment and manufacture their own food through photosynthesis. - This is true because epiphytes are plants that grow on other plants (usually trees) but do not take nutrients from them. They rely on photosynthesis for their energy and nutrients. 2. **Understanding the Reason**: - The reason states that commensalism results in negative effects on the growth and survival of one or both populations. - This statement is incorrect. In commensalism, one species benefits while the other is neither helped nor harmed. Therefore, it does not have negative effects on either population. 3. **Analyzing the Relationship**: - The relationship between epiphytes and trees is an example of commensalism. The epiphyte benefits from the tree by gaining a place to grow, while the tree remains unaffected. 4. **Conclusion**: - Since the assertion is true and the reason is false, the overall conclusion is that the assertion is correct while the reason is incorrect. ### Final Answer: - The assertion is true, and the reason is false.

Water vapour comes out from the plant leaf through the stomatal opening. Through the same stomatal opening carbon dioxide diffuses into the plant during photosynthesis. Reason out the above statements using the following options. (a) Both processes cannot happen simultaneously. (b) Both processes can happen together because the diffusion coefficient of CO_(2) and water is different. (c) The above processes happen only during night time. (d) One process occurs during day time, and the other at night.
