REVIEW: WHAT ARE THE 5 EVIDENCES OF A CHEMICAL REACTION  What are the 5 evidences of a chemical reaction?

SYMBIOTIC RELATIONSHIPS

ECOSYSTEM  A community of organisms that live in an area + their non living surroundings  Biotic & Abiotic factors Organism  Population  Community  Ecosystem

DEPENDENT RELATIONSHIPS Dependent vs. Independent (Dependent depends on others) 1. Producer/Consumer - Slide 2. Predator/Prey – E 27, Mutualism – E Commensalism – E Parasitism – E 31

SYMBIOSIS = LIVING TOGETHER  Close relationship between 2 species

PRODUCER/CONSUMER

DEPENDENT RELATIONSHIPS Write a SIMPLE definition and then DRAW an example Dependent vs. Independent (Dependent depends on others) 1. Producer/Consumer - Slide 2. Predator/Prey – E 27, Mutualism – E Commensalism – E Parasitism – E 31

PREDATION  Predator: kills another organism for food  Prey: organism that gets killed  Predator kills prey for food

MUTUALISM  Both species benefit

COMMENSALISM  One species benefits & the other is neither helped or harmed

PARASITISM  One organism lives in or on another organism and harms it
