Module 4 Review - Marine Science
Module 04 Review
Phytoplankton
(Lessons 04.02, 04.03, 04.04) * What are phytoplankton? * Plankton consisting of microscopic plants. * Know that the three adaptations that allow phytoplankton to float are: cavities in the center of their cells, cells contain oils and fats, and spines around the cavities
* Are phytoplankton the base of the oceanic food chain? * Yes * What things do phytoplankton need to survive? * Light, minerals, and precursors for photosynthesis * What percentage of the Earth’s oxygen are phytoplankton responsible for producing? * 70% * Which type of phytoplankton are responsible for red tide? * Dinoflagellates * What negative effects can red tide cause for the marine environment? * Toxins in fish and shellfish * If upwelling aids in phytoplankton growth, would less upwelling affect phytoplankton numbers? How? * Yes. It would decrease phytoplankton * How does a decrease in phytoplankton affect the rest of the food web? * There would be a decrease in everything else * Know that harmful algal blooms do not cause erosion
* If phytoplankton help reduce carbon dioxide on Earth, what would an increase amount of phytoplankton do for carbon dioxide amounts? * It would reduce carbon dioxide more
Marine Iguanas
(Lesson 04.07) * What do marine iguanas primarily feed on? * Marine algae * What adaptations allow them to live and eat in the water (hint: know about their physical body part changes that are different than their land ancestors)? * * Where do the marine iguanas live (they are only found in this one area of the world)? * Why do these cold blooded organisms lay on the rocks instead of stay in the cold water? * What is the main reason for their decline in population?
Galapagos Islands
(Lessons 04.04, 04.06, 04.07) * Why do the same species on different Galapagos Islands have slightly different traits? * What is the
