9.1

• Ecosystem - All the biotic componets together with the abiotic compotents
• Population - The number of organisims from the same species living in the same area at the same time.
• Community - A group of populations of different species living in the same area at the same time.
• Habitat - The place in a ecosystem where an organism lives.
• Niche - The role of a specific species in the enviorment
• Food chain - A diagram showing the relationship between one producers, primary, secondary and tetriary consumer.
• Food web - A Diagram showing the relationships between multiple producers, primary, secondary and tetriary consumers.
• Trophic Level - The feeding level within a food chain or food web
• When is energy lost

  • During Excretion
  • Respiration
  • Transfer as heat to the enviorment
• Biotic Factors - Producers

  Are organisims at the bottom of the food chain wich conduct photosynthesis
• Biotic Factors - Primary Consumers

  Are consumers within a ecosystem that feed off producers
• Biotic Factors - Secondary Consumers

  Are consumers within a ecosystem taht feed off primary consumers
• Biotic Factors - Tetriary Consumers

  Are consumers within a ecosystem that feed off secondary consumers
• Abiotic Factors

  • Water
  • pH
  • Humidity
  • Salinity
  • Light
• Photosynthesis

  the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product
• Photosynthesis equasion

  carbon dioxide + water + sunlight -> oxygen and glucose.
• Respiration

  The process by wich living things release energy from food to carry out processes of life such as movement
• Respiration Equasion

  glucose + oxygen --> water + carbon dioxide + energy
• Biotic Interactions

  • Competition
  • Predetation
  • Pollination
