Chapter 1: Components of Ecosystem

• why dead things are considered to be biotic?

  because, they were once alive or part of a living thing. Once the dead things are completely decomposed by microorganisms, they are considered abiotic.
• Tapography

  1. Altitude 2. Angle of slope 3. Orientation of slope
• Soil

  1. Nutrients present 2. Acidity 3. Moisture content
• Climate

  1. Light 2. Temperature 3. Moisture 4. Air/Wind
• Abiotics factors

  all the non-living things that are needed for life to exist like Climate, Soil, and Topography
• Abiotic Components of an Ecosystem

  it affects the survival of Biotic components such as temperature, light, water, and nutrients. (non living organisms)
• Decomposers (saprotrophs)


  1. Mostly bacteria and fungi
• Consumers (heterotrophs)

  1. Herbivores 2. Carnivores 3. Omnivores 4. Detritivores
• Producer (autotrophs)

  Chlorophyll-bearing plants, Photosynthetic bacteria, Chemosynthetic bacteria
• Biotic Factors includes:

  Plants/Producers (autotrophs; they can produce their own food), Animals/Consumers (heterotrophs; those that can't make their own food), and Microorganism/Decomposers (saprotrophs; those that feed on organic matter
• Biotic Components of an Ecosystem

  refer to the different kinds of organisms that interact with the environment. (Living organisms)
• Healthy Ecosystem is equal to

  Balance ecosystem
• Homeostasis


  means the ecosystem is balance
• Ecosystem


  basic unit of the environment
