Cheating, also known as exploitation, between organisms is a form of parasitism or specialized predation in which an organism engages in what appears to be a mutualistic relationship with another organism, but does not in fact provide any benefit to the other organism. The relationship between the organisms may be symbiotic, in which case cheating is a form of parasitism, or non-symbiotic, in which case cheating is a form of predation or herbivory. Mites parasitising a harvestman Parasitism is one version of symbiosis (living together), a phenomenon in which two organisms which are phylogenetically unrelated co-exist over a prolonged period of time, usually the lifetime of one of the individuals. ...

In zoology, an herbivore is an animal that is adapted to eat primarily plants (rather than meat). ...
Cheating is often found in situations where there are generalized non-specific mutualisms between broad classes of organisms, such as the relationship between flowering plants and animal pollinators or between mycorrhizal fungi and plants. Classes Magnoliopsida - Dicots Liliopsida - Monocots The flowering plants (also angiosperms or Magnoliophyta) are one of the major groups of modern plants, comprising those that produce seeds in specialized reproductive organs called flowers, where the ovulary or carpel is enclosed. ...
A pollinator is the agent that moves pollen from the male anthers of a flower to the female stigma of a flower to accomplish fertilization or syngamy of the female gamete in the ovule of the flower by the male gamete from the pollen grain. ...

Examples
Some insects and birds engage in a behavior called nectar robbing in which they harvest nectar without pollinating the plant; nectar robbers are often close relatives or mimics of pollinating species. Another example would be myco-heterotrophic plants that take carbon from fungi in a shared mycorrhizal network without contributing anything to the fungal symbiont. These parasitic plants act as "mycorrhizal cheaters" in such systems. In Greek mythology, nectar and ambrosia are the food of the gods. ...
