Adaptations: simplification of the digestive system in parasites; in parasitic plants, feeding on host juices has led to a reduction in the photosynthesis system and the loss of chlorophyll; the absence of direct contact with environmental factors in parasites has led to a simplification of the structure of their nervous system and reduction of sensory organs; the limited size of the parasite’s habitat is compensated by the small size of their body and the simplification of the external structure, and the diffusion difficulties are compensated by an increase in the ability to reproduce (enormous fecundity).
