• consumer - animal that eats other animals or plants
• biotic factors- factors that are related to living things( volume of food, disease)

• the distribution of living organisms can be affected by abiotic factors
• sampling techniques to measure biotic factors- Quadrat and pitfall trap
• photosynthesis is the process where green plants use light energy to make sugar (glucose)
• Plants can help to sustain life by providing:

  -food

  -medicine

  -habitat

  -raw materials

  -decoration
• Pests are organisms which reduce the growth and productivity of crops
• Bio accumulation is the build up of toxins within a food chain
• Biological control is defined as the reduction of a pest population by natural predators
• Photosynthesis equation
