Bee consistency. Some solitary bees have advanced types of pollen-carrying structures on their bodies. A very few species of solitary bees are being cultured for commercial pollination. Most of these species belong to a distinct set of genera which are commonly known by their nesting behavior or preferences, namely: carpenter bees, sweat bees, mason bees, plasterer bees, squash bees, dwarf carpenter bees, leafcutter bees, alkali bees and digger bees. Most solitary bees nest in the ground in a variety of soil textures and conditions while others create nests in hollow reeds or twigs, holes in wood. The female typically creates a
Orchid mycorrhiza which is the absorption of nutrients form dead cells..The key nutrients involved in the majority of the transfer between fungi and orchid plants are carbon, nitrogen and phosphorus . Orchid mycorrhizal interactions are unique in the flow of nutrients. Typically in arbuscular mycorrhizal interactions the plants will unidirectionally supply the fungi with carbon in exchange for phosphorus or nitrogen or both depending on the environment , but orchid mycorrhizal nutrient transfer is less specific (but no less regulated) and there is often bidirectional flow of carbon between the fungus and plant, as well as flow of nitrogen and phosphorus from
