Food Chains By: Nicole Charles

INTRODUCTION A food chain is a community or organisms where one member is eaten in turn by another member. Food chains can involve any type of living thing including, plants, animals, and people. These food chains ultimately become a food web: a community of organisms where there are several interrelated food chains.

Levels of Food Chains Level 1 – Producers – organisms that make there own food Level 2 – Primary Consumer (herbivores) – only eat plants Level 3 – Secondary Consumer (carnivores) – eat the herbivores Level 4 – Tertiary Consumer – carnivores or omnivores
