Plants and animals have distinct functions that contribute to ecosystems. Plants: Photosynthesis: Plants convert light energy into chemical energy (sugars) using carbon dioxide and water, releasing oxygen. This forms the base of most food chains. Support and Structure: They provide physical structure for habitats and food sources for other organisms. Water and Nutrient Cycling: Their roots help stabilize soil and absorb nutrients, while transpiration releases water vapor into the atmosphere. Animals: Consumers: Animals obtain energy by eating other organisms (plants or other animals). Movement and Dispersal: They can move, which helps in pollination, seed dispersal, and nutrient distribution. Decomposition: Some animals, like decomposers, break down dead organic matter, returning nutrients to the soil. Ecosystem Engineers: Some animals significantly modify their environment, creating habitats for others.
