The Fungi Kingdom is a diverse group of organisms that includes mushrooms, molds, and yeasts. Unlike plants, fungi do not perform photosynthesis; instead, they obtain nutrients by breaking down organic matter. They play a crucial role in ecosystems as decomposers, recycling nutrients back into the soil. Fungi reproduce through spores, which can be spread by wind, water, or animals. Some fungi form symbiotic relationships with plants, such as mycorrhizae, which help plants absorb water and nutrients. Others can be harmful, causing diseases in plants and animals, including humans, like athlete's foot or ringworm.
