Ecology

• Food chain 


  A flow diagram that begins with a plant and shows how energy is passed through a series of organism in a community
• Energy flow 


  Pathway of energy from one organism to the next in an ecosystem due to feeding or consumption
• Aquatic factors 


  Only apply to organisms that live near or in aquatic environments such as a pond sea or lake

  factors include m

  salinity

  oxygen concentration

  currents
• Edaphic factors are nom living factors that refer to the soil

  eg soil type

  soil ph

  soik minerals content

  humus
• Climatic factors 


  Are the average weather conditions that affect the community in an ecosystem

  eg rainfall

  wind

  day length

  humidity
• Abiotic factors

  eg. Light

  aspect

  temp

  oxygen concentration
• Biotic factors 


  Living factors that affect an organism

  competitions

• Community 


  Refers to all the population in an ecosystem
• Population

• Trophic levels 


  Position of an organism in a food chain
• Niche 


  Is the functional role of an organism in an ecosystem
• Food web 


  A series of interconnected food chains that show all the feeding connections in a habitat and shows us the concept of interdependence
