TODAY

• Predation
• Competition
• Symbiosis 

KERBOODLE PAGES 294-297

"PREDATION"

• The predator hunts the prey, kills it and eats it.
• Predators and prey are adapted to each other

"COMPETITION"

• When multiple different organisms compete for the same resource: 
• within the species
• between species

"SYMBIOSIS"

• Mutualism   (+/+)
• Commensalism   (+/0)
• Parasitism   (+/-)

"MUTUALISM (+/+)"

• Both organisms benefit from the relationship
• None are harmed

"COMMENSALISM (+/0)"

• One organism benefits from the relationship and for the other there is no benefit, but also no harm
• None are harmed

"PARASITISM (+/-)"

• One organism benefits from the relationship and the other is harmed
• The host is harmed

PROJECT SPRINT 2:

• Create a predator prey cycle DIAGRAM for your apex predator and one of it’s prey.
• write 3 paragraphs that show (pictures & min 200 words each), each paragraph must cover:

• extra: vwo must choose one minimum

Star 1

Find and explain a type of symbiosis that your APEX predator does. (Pictures and 250 words)

Star 2

Look up a population research that has been done about your apex predator. How did the scientists collect the data, what was the goal and conclusion of this research? (300 words and pictures)

Star 3

What now?

• work on sprint 2
• work on your project
• work on your logbook
• work on your mindmap
