Statement 2 (hot and wet climate throughout the year) provides the ideal temperature and moisture conditions for rapid plant growth. Statement 3 (intense sunlight for photosynthesis), due to their location near the equator, ensures high energy input for primary production. Statement 1 (fertile soil) is generally incorrect; rainforest soils are often poor in nutrients as rapid decomposition and uptake mean most nutrients are stored in the biomass, not the soil. Statement 4 (seasonal change) is incorrect; tropical rainforests exhibit minimal seasonal temperature and rainfall variation compared to other biomes, and nutrient cycling is continuous.
