Ecological Relationships and Competition

Teacher Judith introduces ecological relationships in ecosystems, discussing populations, communities, and interactions. She explains symbiotic relationships like mutualism, commensalism, and parasitism, providing examples. The video also covers competition and predation among species. A learning task concludes the session, reinforcing the concepts discussed.
