FOOD CHAIN/FOOD WEB - REVIEW

FOOD CHAIN - ACTIVITY

FOOD CHAIN REVIEW - ACTIVITY


REVIEW:

When we talk about the relationships among organisms in an ecosystem, the most important is how they relate to each other as predators and prey. The best means of illustrating these relationships is through food chains and food webs.


  • Organisms interact with each other, and the most common interaction is within the structure of a food chain in which one organism is the food and energy source for another organism. 
  • All food chains start with plants as producers because they can photosynthesize and capture sunlight energy. 
  • Animals are consumers and eat either plants or each other. 
  • Several food chains can be interwoven to create a food web in which many organisms interact with each other.
