Symbiotic Relationships in Ecology

Mrs. Pucket introduces symbiosis, a close association between species, and explains five types: predation, competition, mutualism, commensalism, and parasitism. Predation involves one organism consuming another, while competition involves organisms vying for limited resources. Mutualism benefits both organisms, commensalism benefits one without affecting the other, and parasitism benefits one at the expense of the other. Students are encouraged to take detailed notes and review the video as needed.
