Adenium obesum is grown as a houseplant in temperate and tropical regions. Numerous hybrids have been developed. Adeniums are appreciated for their colorful flowers and unusual thick caudices. They can be grown for many years in a pot and are commonly used for bonsai . Because seed-grown plants are not genetically identical to the mother plant ...
Earthworms are soil-dwelling detritivores. Detritivores (also known as detrivores, detritophages, detritus feeders or detritus eaters) are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces ). [1] There are many kinds of invertebrates, vertebrates, and plants that carry out coprophagy.
