A lichen is a composite organism consisting of a fungus (the mycobiont) and a photosynthetic partner (the photobiont or phycobiont) (usually algae) growing together in a symbiotic relationship.

Notes:
Biomass is the amount of living material in an organism. The pyramids of biomass represent the relationship between different trophic levels in terms of biomass. In grassland and forest ecosystems, there is generally a gradual decrease in biomass of organisms at successive trophic levels from the producers to the consumers. Their pyramid of biomass is upright. In aquatic ecosystem the producers are small organisms with least biomass and the biomass gradually increase towards the apex of the pyramid. Thus the pyramid of biomass of aquatic ecosystems is inverted in shape.

Notes:
Silviculture is the practice of managing and caring for forests to promote their growth and development. It involves a range of activities, such as planting and tending to young trees, thinning out overcrowded areas, and controlling pests and diseases. The goal of silviculture is to create healthy, thriving forests that provide a range of benefits, including clean air and water, wildlife habitat, and timber for various uses.

Notes:
Water vapour also accounts for the largest percentage of the greenhouse effect, between 36% and 66% for clear sky conditions and between 66% and 85% when including clouds.
