Marine Bio- Day 7&8 Drill: Explain why you would need to research fish before placing them all into one aquarium. Outcome: Discuss the types of food chains and webs that exist in a marine ecosystem. Agenda: Discuss interactions between marine organisms Discuss Aquarium Project expectation and rubric

Marine Food Web - and – Food Chain

Food Chain Producer: Makes their own E from the Sun A straight line or who eats who Producer  Primary Consumer  Secondary Consumer  Tertiary Consumer  Quaternary Consumer Producer: Makes their own E from the Sun Consumers: Eats another organism to their E

Food Chains Example: Food chains will always begin with a producer! Phytoplankton  Zooplankton  Sunfish  Small Shark  Large Shark Food chains will always begin with a producer!

Food Chain What would happen if I removed ALL of the zooplankton from the pyramid/chain? Large shark Small shark Sunfish Zooplankton Phytoplankton

Food Web Multiple food chains put together where multiple organisms can feed on the same prey! This allows for competition. If an organism will not adapt to a new food source it will die! If an organism will adapt to a new food source it will live and possibly migrate and evolve!!

Food Chains Can be written with the arrows OR as a pyramid Has the least E Quaternary Tertiary Secondary Primary Producer Has the most E

Food Chain/Web Worksheet As a group answer the questions on both sides of the worksheet Use your notes, books, and peers. When done look at the food web on the worksheet In a group or by yourself will be sketching the zones of the ocean on poster board, placing each organism in a zone (some may not go in all zones) You will need to label Producer, P Consumer, S Consumer, T Consumer, and Q Consumer. You will need to give a brief description of what is occurring in the food web. This will be placed in the hallway! Please make it neat!
