3.
Photosynthesis is decreases rapidly during the winter in the biome ?
Correct Answer
C. Temperate Rain Forest
Explanation
The correct answer is Temperate Rain Forest. Photosynthesis is the process by which plants convert sunlight into energy. During winter, the availability of sunlight decreases due to shorter days and less direct sunlight. In temperate rain forests, the dense canopy of trees blocks much of the sunlight from reaching the forest floor even in the summer, and this effect is further amplified during the winter. Therefore, photosynthesis decreases rapidly during the winter in temperate rain forests.
