2nd QTR L3 GR7

• Deals with the study of the relationship between living organisms and their environment

  Ecology
• from the Greek word "oikos" that means


  house
• Greek word "logos" means

  study of
• Scientist who study ecology are called

  ecologists
• is a life-form composed of related parts maintain different essential processes

  organism
• • group of organism; belongs to the same species; living in the same area

  population
• • Different population of different species interact with one another

  community
• • When members of the community interact with one another and their surroundings, they make up an ECOSYSTEM


  community
• Smallest functional unit of Ecology;

  ecosystem
• major ecosystem type

  biome
• it includes desert, rain forest, savanna, tundra, and taiga

  biome
• composed of living and non-living factors


  ecosystem
• smallest functional unit of ecology

  ecosystem
• Highest level of ecological hierarchy

  biosphere
• includes the zone of land, air and water

  biosphere
• it is the totality of all the ecosystems

  Biosphere
• are the living organism in the environment

  biotic factors
• what are the 5 biotic factors

  animals, plants, fungi, bacteria, and protists
• 5 major ecosystems (biome)

  desert, rain forest, savanna, tundra, and taiga
• biotic factors are grouped into three major groups, which are

  Autotrophs, Heterotrophs and detritivores
• producers are also called

  autotrophs
• consumers are also called

  heterotrophs
• decomposers are also called

  detritivores
• Greek word "auto" means

  self
• Greek word "troph" means


  food
• are organisms that make their own food using inorganic materials and energy sources


  producers
• are organisms that eat other living organisms in order to obtain energy

  consumers
• Greek word "hetero" means

  other
• what are the 3 types of consumers?


  herbivore, carnivore, and omnivore
• ecosystems also contains decomposers


  true
• organisms that use organic compounds from producers and consumers as their source of energy

  decomposers
• They are important to ecosystems because they break down materials from other living things into simpler forms, which can then be used again by other organisms

  decomposers
• decomposers include:

  soil, bacteria, fungi, worms, flies and other organisms
• are the non-living components found in the environment

  abiotic factors
• abiotic factors include

  air, water, sunlight, humidity, temperature, soil, rainfall, and nutrients in the soil
• Main source of energy

  sunlight
• Indispensable for plants to perform photosynthesis


  sunlight
• Activates the production of Vitamin D

  sunlight
• UV rays inhibit the growth of bacteria


  sunlight
• Serves as home to many of the animals and microorganisms

  soil
