Document Summary
Commensal is m one species is helped but host is neither helped men harmed. Many microbiota : predation predator attacks t kills prey outer t inner invades. Vampiro occurs attaches to prey, cell t secretes enzymes that degrade prey cytoplasm. I epsilonproteobacteria) invade prey all degrade prey cytoplasm t secrete enzymes that: parasitism parasite uses host as habitat and source of nutrients. Definitive host host in which sexual maturity occurs. Vector : small host transmits parasites tolarger hosts b- amen sal is m a competition. Amensausm : the on another adverse effect of organism . Release one organism on of antibiotic negatively affects the other organism. Between species in a community that to try acquire the same resource one organism tries to take over the other. Humans than own carry to x more microbial cells. Internal tissues are sterile skint mucous membranes are constantly in contact with biota.
