FOOD CHAINS and FOOD WEBS There are two types of feeding relationships: autotrophic and heterotrophic. Autotrophic organisms make their own food by the process of photosynthesis e.g. plants. Heterotrophic organisms cannot make their own food (i.e. cannot carry out photosynthesis)‚ therefore must eat other organisms to get their nutrients e.g. animals. A food chain is the feeding relationship among organisms or the series of living organisms that eat each other. A food chain shows the transfer
