Ecology Video Questions Name____________________________ 100 greatest discoveries: hydrothermal vents www.youtube.com/watch?v=D69hGvCsWgA (5min) How much energy from each trophic level is passed along up the food chain to the next level? Why does productivity switch from the northern to southern hemisphere during every year? True or false: productivity refers to the amount of biological plant mass in an environment Compare the amount of biomass at the producer level to the that at the levels above it. The food chain by Richard Kern www.youtube.com/watch?v=0ZOvqYypOuo (4 minutes) The food web by Richard Kern www.youtube.com/watch?v=MGODmyXkkPU (3:07) 1. Why is a food chain not complete enough to explain energy flow in an ecosystem? How do the formulas for photosynthesis and respiration compare to one another? True or false: plants are able to use most of the energy available from the sun Energy Flow in ecosystems www.youtube.com/watch?v=lnAKICtJIA4 (7:45) What are the two sources of energy available to producers on Earth? What was discovered in 1977 at 8000 feet deep in the Pacific? 2. Is a primary consumer a herbivore or a carnivore? Describe the temperature and light levels here. 3. What makes the purple gallinule an omnivore? What do we call each step on a food chain? 7. Why are food chains short?

List four steps of a potential food chain that could be found in the intertidal zone and label the producer, the herbivore, and the carnivores. A mussel may filter many gallons of water each day through its body. What does this do to the levels of contamination that might be found in their tissues? Bacteria are often overlooked by students when they consider food webs. Why is their role important? Bacteria will act as decomposers and break down dead organisms chemically. Why is this important? What is the source of energy for the food chains found in the deep ocean at these vents? What adaptations do animals have that enable them to survive the pounding surf? Many of the animals of the intertidal zone are filter feeders. What does that mean? Why do we need data about how human activities affect the life in Puget Sound? In terms of the food web of the intertidal zone, why are plankton important? The intertidal zone https://www.nfb.ca/film/intertidal_zone (15 min) What is chemosynthesis and what organisms at the vents carry it out? Taking the Pulse of Puget Sound https://vimeo.com/31635924 Is the sea star a carnivore or a herbivore? How do you know? What are the dangers for animals at low tide? Many zooplankton are actually what? What is the intertidal zone? What is phytoplankton? What is detritus?
