Document Summary
Parasites and organisms line in or on tissues of their host and draw resources from their host negative for host positive for pathogen. Epiphytes are able to live on their host and cause no harm this is a commensal interaction which is neutral for at least one participant. Positive interactions among species are common in nature ex birds and fish that remove parasites off other animals the roots of most plants are intimately connected with fungi in associations called mycorrhizae. Mycorrhizae and lichen are an example of a symbiotic relationship symbiosis involves organisms that live in close proximity to each other. Interactions: predation, parasitism, and competition o o o. Adelina reduces density of tibolium populations and alter outcome of competition between t. confusum and t, castaneum. Chapter 15 mutualism, parasitism and disease: did experiments to see if acacias really do need ants ants significantly improve plant performance they reduce populations of herbivore issues.
