Marine Biology DAY 3 Drill What are some

Marine Biology DAY 3 �Drill: What are some abiotic and biotic factors that would affect organisms in a salt water fish tank? �Outcome: Define the different relationships between marine organisms. Compare marine symbiotic relationships. �Agenda: �Discuss interactions between marine organisms �Discuss Aquarium Project Expectations and Rubric

Competition �What is Competition? �When two or more species compete for the same resource, space/food/light. � Ex. Connells barnacles �There are two types of competition: �Intraspecific - within one species �Interspecific - between species

Competitive Exclusion �What is Competitive Exclusion? �When a less successful species is replaced by a more successful one. �This happens often when an invasive species appears. ot n ism he n a g Or ve to t nati area

Symbiosis �Symbiosis - ecological relationship between the individuals of two (or more) different species �Four examples of symbiosis: 1) Parasitism – One benefits, the other is harmed (+ , - ) 2) Commensalism – One benefits, the other is neither helped nor harmed ( + , O ) 3) Mutualism – Both benefit ( + , + ) 4) Predator/Prey – One hunts and kills the other (+ , - )

Parasitism Examples Cymothoid isopod and a snapper fish Grouper Fish with a parasite

Commensalism Examples Remora fish Pearl fish and a sea cucumber Shark with a remora fish

Mutualism Examples Boxer Crab and anemone Clown Fish and anemone

Predator/Prey Examples Orcas and seal Great White and seal

Symbiotic Worksheet �Read the 10 scenarios and determine if they are M: Mutualism, P: Parasitism, or C: Commensalism �When done show me your answers… if correct you can continue on your aquarium project! �Aquarium project �Open this poiwerpoint: Goodies Science Godich Marine. Bio U 1 d 3_Sym. Relate �Go to the last slide and see additional requirements

Aquarium Project Why is it so great? �Goals for the Aquarium Project �Name of Aquarium �Location �Why should people come �Cost (enter / build) �Organisms in the aquarium �Layout / Blue. Print (sketch) with explanation �How they environment meets the needs �Filters/Temp control/Salinity �Organized and colorful (pictures!) Are there additional attractions? How will you stop them from eating each other? Is the temp, lighting, space enough? How will you make it meet the needs/lifestyle of the orgs?
