Document Summary
Below ground roots of most plants interact with fungi in associations called mycorrhizae increasing capacity of plant to get nutrients. Symbiotic relationships involve organisms that live in close proximity to one another, if far apart - non-symbiotic. Mutualisms - interactions between different species that have net benefit to both. If species can live without mutualistic partner - facultative mutualism if not obligate partners mutualisms. There are potential webs of mutualistic interactions, not just one interaction with the other. Parasites can alter the behaviour of their hosts to benefit them through helping them reproduce and transmit parasite. Ticks cause high amount of self grooming causing moose to lose winter coat making it white. Only consume blood from moose and drastically affect health and appearance. Behavioural shift of increased grooming causing hair loss. The number of ticks on the moose is good predictor of how many will be alive the next year.
