What are the different ecological relationships?
Ecological Relationships. Students watch videos and discuss ecological relationships with a focus on observing symbiosis. Then they classify the ecological relationships they observe as mutualism, commensalism, and parasitism.
Why do organisms in symbiotic relationships have different niches?
Organisms in symbiotic relationships have evolved to exploit a unique niche that another organism provides. These relationships are based on the advantages that can be gained by finding and using a previously unexploited niche.
What is the symbiotic relationship between a shark and a remora?
Elicit from students that the shark and the remoras, the smaller fish below the shark, have a symbiotic relationship called commensalism, where the remoras benefit from holding onto the shark, but neither species is harmed. Tell students that this commensal relationship is why Greg Marshall, marine biologist and filmmaker, invented Crittercam.
Why is ocean life not evenly distributed?
Due to interactions of abiotic factors such as salinity, temperature, oxygen, pH, light, nutrients, pressure, substrate and circulation, ocean life is not evenly distributed temporally or spatially, i.e., it is “patchy”.
What is ececology?
Ecology: The study of the interrelationships between living organisms and the living and non-living components and processes in an environment.
What is an interrelationship between organisms?
relationship between organisms of different species, in which both organisms benefit from the association. relationship between organisms where one organism (a parasite) lives or feeds on the other, usually causing harm. animal that hunts other animals for food. animal that is hunted and eaten by other animals.
What are the types of competitive relationships between animals?
Competitive Relationships: Plant and animal species compete over food, water, territorial space and mating with the opposite sex. The Principle of Competitive Exclusion:explains that no two species can occupy the same niche (food or space) successfully in a stable community. Closely related species therefore live far from one another.
