study of relationships
& interactions of a living
organism with their environment

• Ecology

• Niche

• Ecosystem

• Biotic Factor

the physical parts of the environment that are nonliving

• food chain 

• biotic factor

• abiotic factor

• 
  biome

examples of abiotic factors

• - food
  - shelter
  - water
  - mates
  - sunlight
  - oxygen
  - carbon dioxide

• - air/atmosphere
  - water/amount of moisture
  - sunlight
  - soil
  - inorganic compounds
  - pH
  temperature/climate

• - producers
  - consumers
  - decomposers

a relationship where both organisms benefit;

• parasitism

• commensalism

• mutualism

• predator-prey relationship

the surroundings of an organism

• population

• niche

• habitat

• environment

a relationship where one organism benefits and the other is neither helped nor harmed

• mutualism

• commensalism

• parasitism

• host
