Detailed explanation-1: -Saguaro cacti are highly important to both animals and people. Small birds excavate nest cavities inside the saguaro’s pulpy flesh, and large ones build stick nests among its arms. Saguaro flowers, fruit, and flesh variously provide nectar, moisture, and food for birds, bats, mammals, reptiles, and insects.
Detailed explanation-2: -The leaves of a cactus are reduced to thin spines to prevent the loss of water through transpiration. These spines cannot really perform photosynthesis. Instead, photosynthesis is carried out by the thick green stem.
Detailed explanation-3: -In cactus, the leaves are modified into spines. This is to prevent the loss of water due to transpiration. The stems are green and have chloroplasts. So, stem performs photosynthesis in succulents.
