SCIENCE 7

• Symbiotic


  Two different interacting organisms are living close together
• Non-Symbiotic


  Two different interacting organisms are not living close together
• Symbiotic relationships


  • Mutualism
  • Commensalism
  • Parasitism
• Mutualism


  Both organisms benefit from one another
• Mutualism


  • Clownfish and sea anemone
• Commensalism


  One animal benefits from another without harm
• Commensalism


  • Sharks and remora/sucker fish
• Parasitism


  The one who causes harm lives in the organism
• Types of Parasitism


  • Ectoparasitism
  • Endoparasitism
• Parasitism


  • Fleas, lice
• Predation


  The preying of one animal on others
• Predation


  • Lions and zebras
• Herbivory


  The animal eats a plant or plant-like organism
• Herbivory


  • A zebra grazing on grass
• Competition


  The competition of organisms over resources
• Competition


  • Trees growing taller to get more sunlight
• Amensalism


  Population is inhibited/harmed by another population, said population is not affected
• Amensalism


  • A stampede trampling a field of grass (the grass will be destroyed but not the stampede)
• Ecological Niche


  The role of an organism in its particular ecosystem
• Trophic Niche


  The type of niche to give to species as to what it eats or will be eaten
• Trophic Function


  The position of an organism or and understanding
• Energy Function


  Organisms eat to keep the energy flowing. When organisms eat, the energy from the food eaten is transferred.
• Energy Transfer


  Organisms eat to keep the energy flowing and help transfer it. Supports the ecosystem and the survival of all the organisms in the ecosystem. The sun's major source of energy for organisms.
• Food Chain


  A linear sequence to which energy is passed from one organism to another
• Food Web


  A set of multiple food chains in an ecosystem
• Trophic Level


  10% Rule - Only 10% of the energy transfers each time, meaning energy decreases 90% when transferred
• Natural Resources


  Materials or substances that are used to support life and meet people's needs
• Types of Natural Resources


  • Renewable resources
  • Non-renewable resources
• Troposphere


  Where all life on earth lives in and weather is formed, traps the sun's heat and greenhouse
• Stratosphere


  Consists of the Ozone layer which protects us from the harsh solar radiation that the sun produces, where planes and jets fly
• Mesosphere


  The coldest layer, where meteoroids burn up
• Thermosphere


  Also known as the IONOSPHERE, very hot because it absorbs all the sun's heat and radiation
• Exosphere


  Temperature varies from very hot to very cold, depending on the time of day, where the space satellites are located
• ITCZ


  An area where trade winds meet, usually situated near the equator, appears as a band of clouds consisting of showers of occasional thunderstorms
• Monsoon


  A change in direction of the winds, causes wet and dry seasons in the tropics
• Seasons


  Periods of a year with distinct climatic conditions, caused by the earth's tilt on its axis
• Philippines Seasons


  Wet Season - June to November, high amount of rainfall

  Dry Season - December to May, low amount of rainfall
• Types of Seasons in the Philippines

  • Type 1 - Dry: November to April, Wet: rest of the year (prevalent during June to September due to Habagat)

  Type 2 - Maximum rainy season, no dry season, max. rainfall - November to January

  Type 3 - Not pronounced, wet season does not come up throughout the year, Dry: November to April

  Type 4 - Even distribution of rainfall throughout the year
• Tropic Zone


  The region between the Tropic of Cancer and the Tropic of Capricorn
• The earth is tilted, therefore some countries experience more sunlight than others, which is why we have wet and dry seasons in the tropic zone near the equator
