In which of the following habitats, the average temperatures exceeds \(100^{\circ} \mathrm{C}\)
1 Thermal springs
2 Deep-hydrothermal vents
3 Tropical deserts in summer
4 Both (1) and (2)

Assertion : There is no loss of water by transpiration below the forest canopy Reason : Forest canopy is exposed to sunlight and wind fury and acts as effective wind and light barrier
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
The second layer, the canopy, is formed by trees that grow between 60 and 150 feet tall (18-46 meters). The trees form a dense habitat that sustains most of the plant and animal life found in tropical rainforests. The canopy layer also serves as a sunshade for the rainforest below, absorbing a majority of the sunlight. Only about two to five percent of the sunlight penetrates the canopy and reaches the forest floor. Hence below the canopy layer, transpiration is not possible. Both Assertion and Reason are false
