  1. Warm-up: October 6, 2010 A new organism is discovered in the rocky intertidal zone. Which of the following characteristics helps the organism to survive in this particular ocean zone? • It has a hard shell and can cling to surfaces • It gets energy from chemicals in thermal vents. • It has a shiny body and glows. • It serves as food source for land animals.

  2. Activator: Think of a word or phrase that describes “relationship” for each letter of the word. Write this in your notebook. You will refer back to it at the end of the week. • Now share your response with your elbow partner R E L A T I O N S H I P S

  3. Relationships in Ecosystems

  4. Ecosystem • All the living and nonliving things that interact in an area.

  5. Populations • All of the same species in an ecosystem www.intrasystems.gr www.nkf-mt.org.uk

  6. Competition • All living things compete for • Food • Space • Competition limits population growth www.opim.wharton.upenn.edu

  7. Limiting Factors • Anything that restricts or controls the number of individuals in a population www.bahamascommerce.com

  8. Carrying Capacity • The largest number of individuals of one species an ecosystem can support www.wwt.org.uk

  9. Symbiosis • Any close relationship between species en.wikipedia.org

  10. Commensalism • A relationship in which one species benefits and the other is neither helped nor harmed Shark & remora Barnacles on whale www.community.webshots.com www.cbu.edu

  11. Mutualism • A relationship in which both species benefit Pollination www.biology.clc.uc.edu Cleaner fish Lichens: algae + fungus www.orn.mpg.de www4.tpgi.com.au
