1. Living things live together in relationships called symbiosis.

2. Parasitism Mutualism Commensalism SYMBIOSIS
There are three types of symbiotic relationships. At least one organism will benefit in all types of symbiosis
Parasitism
Mutualism
Commensalism

3. Competition When two species compete, their niches overlap
intraspecific -within the same species
interspecific between different species

4. Predator or Prey?
Predation – act of one organism eating another organism
Predator – organism that does the eating
Prey – organism that gets eaten

5. Most Consumer Species Feed on Live Organisms of Other Species

Camouflage
Chemical warfare

6. Most Consumer Species Feed on Live Organisms of Other Species
Prey may avoid capture by
Camouflage

8. Parasitism one organism benefits and the other is harmed.
organism that benefits is called the parasite
the organism that is harmed is called the host.
It is different from a predator, because it usually does not kill the organism it feeds on.
Examples: Fleas, leeches, worms, mites

13. Mutualism

14. Commensalism
A relationship in which one species benefits and the other species is neither harmed or helped.
Example: Elf owl creating small hole for nest in the cactus.
