There are different types of parasitism and they are as follows:

Cattle egrets have adapted to feed on the disturbed insects flushed from the grasses by the cattle. The cattle receive no benefit, but the cattle egrets benefit from the food source. For another example, nurseplants are found in many biomes.

A tick on the back of a giraffe or other organism is an example of parasitism. The tick is sucking on the giraffes blood, causing it harm, and potentially giving the giraffe an infection. It is an example of parasitism because the tick is causing harm to the giraffe, but the tick is benefitting from it.

A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host. A few examples of parasites are tapeworms, fleas, and barnacles.

Examples of parasites include mosquitoes, mistletoe, roundworms, all viruses, ticks, and the protozoan that causes malaria.

• Obligate Parasitism: Obligate parasites are wholly reliant on the host organism in order for them to survive.
• Facultative Parasitism:
• Ectoparasitism, Endoparasitism, and Mesoparasitism:
• Epiparasitism:
• Social Parasitism:
• Brood Parasitism:

Parasitism is an association of organisms where one organism is benefitted at the expense of other. Whereas, the association of organisms wherein one organism is benefitted while other remains unaffected is called as Commensalism. Mutualism is the association of organisms wherein both are benefitted.

Amensalism is the relationship between two organisms, where one is hurt. A prime example of amensalism is penicillin killing bacteria. The bread mould penicillium secretes penicillin that ultimately kills bacteria. In this contact between two organisms, one is destroyed or inhibited, and other remains unaffected.

Symbiosis refers to a close and prolonged association between two organisms of different species. Mutualism refers to mutually beneficial interactions between members of the same or different species. Mutualistic interactions need not necessarily be symbiotic.

Symbiosis is the phenomenon by which two organisms maintain relationship with each other to be mutually benefitted. Organisms involved in this type of relationship are called as symbionts. e.g. Rhizobium bacteria and Leguminous plants are symbionts exhibiting symbiosis.

Symbiosis is a close relationship between two species in which at least one species benefits. Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed.

Humans as a biological species exist in symbiotic relations with some portion of the whole of plants and animals, which we call “agricultural” or “domesticated.” Our welfare as a biological species directly depends upon the extent to which we provide for the welfare of our symbionts: the agricultural plants and animals …

Humans live in symbioses of various intensities with a number of domesticated animals and plants. To varying degrees, these cultural symbioses are mutualistic, with both humans and the other species benefitting.

Originally Answered: Do plants and humans have a common ancestor? Yes. The last common ancestor would have been an early eukaryote protist, around 2 billion yeras ago.

Plants are crucial for human survival, providing nutrition, warmth, clothing, and shelter, as well as the air that we breathe. Plants also enhance our environment by making it more beautiful and thereby enriching our lives and increasing our wellbeing.
