CRSD Videocast 9.aviEcology
In this video, created by the Council Rock staff, the concepts of Ecology are reviewed. This video reviews energy transfer in the ecosystem, biotic interactions, and succession.
Ecological Relationships with the Amoeba Sisters
In this video, the Amoeba Sisters explore several ecological relationships. Ecological relationships discussed include predation, competition, and symbiotic relationships (parasitism, mutualism, and commensalism).
Food Webs and Energy Pyramids with the Amoeba Sisters
In this video, the Amoeba Sisters explore food chains, food webs, energy pyramids, and the power of biodiversity. This video also introduces general vocabulary for the unit of ecology.
Carbon and Nitrogen Cycles with the Amoeba Sisters
In this video, the Amoeba Sisters explore the cycling of carbon among carbon reservoirs, then discover the importance of nitrogen, essential for amino acids and nucleotides, and learn about the nitrogen cycle.
Ecological Succession with the Amoeba Sisters
In this video, the Amoeba Sisters discover a process that truly demonstrates nature's grit: ecological succession! The Amoeba Sisters introduce both primary and secondary succession.
