Ornithomimosauria ("bird-mimic lizards") are theropod dinosaurs which bore a superficial resemblance to the modern-day ostrich.They were fast, omnivorous or herbivorous dinosaurs from the Cretaceous Period of Laurasia (now Asia, Europe and North America), as well as Africa and possibly Australia.

The relationship is therefore classified as mutualistic. [1] Symbiosis (Ancient Greek συμβίωσις symbíōsis: living with, companionship < σύν sýn: together; and βίωσις bíōsis: living) [2] is any type of a close and long-term biological interaction, between two organisms of different species.
Parasitism is a relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life. [20] The parasite either feeds on the host, or, in the case of intestinal parasites, consumes some of its food.
Cyanobionts play a variety of roles in their symbiotic relationships with the host organism. [2] [4] [5] They function primarily as nitrogen- and carbon-fixers.However, they can also be involved in metabolite exchange, as well as in provision of UV protection to their symbiotic partners, since some can produce nitrogen-containing compounds with sunscreen-like properties, such as scytonemin and ...
The relationship between jellyfish and zooxanthellae is affected a little differently than coral in terms of climate change despite both of them being a part of the cnidaria family. [23] One study suggested that certain species of jellyfish and their symbiotic zooxanthellae may have some type of resistance to decreasing pH caused by climate ...
Azorhizobium caulinodans is a species of bacteria that forms a nitrogen-fixing symbiosis with plants of the genus Sesbania. [2] The symbiotic relationship between Sesbania rostrata and A. caulinodans lead to nitrogen fixing nodules in S. rostrata. Bacterial chemotaxis plays an important role in establishing this symbiotic relationship. [3]
European mistletoe is an example of an ectosymbiotic parasite that lives on top of trees and removes nutrients and water.. Ectosymbiosis is a form of symbiotic behavior in which an organism lives on the body surface of another organism (the host), including internal surfaces such as the lining of the digestive tube and the ducts of glands.
Each symbiotic relationship displays a unique ecological niche, which in turn can lead to entirely new species of host species and symbiont. [ 3 ] It is particularly interesting that it took so long to discover the marine microbial symbiosis because nearly every surface submerged in the oceans becomes covered with biofilm , [ 6 ] including a ...
