Is a lichen a producer a consumer or a decomposer?

Answer 1

Lichens are primarily considered producers because they are composed of a symbiotic relationship between fungi and photosynthetic organisms, usually algae or cyanobacteria. The photosynthetic partner produces organic matter through photosynthesis, while the fungal component provides structure and protection. This unique partnership allows lichens to thrive in various environments, contributing to ecosystems by producing oxygen and serving as a food source for other organisms.
