To understand how plants and animals interact, scientists make diagrams called food chains. A food chain shows a sequence of living things in which one organism eats the one below it. Most animals eat more than one thing, so to show ALL the feeding relationships, we use food webs which are made of many intersecting food chains.
To better understand the food web definition….
LET’S BREAK IT DOWN!
Energy in food can be traced back to the sun.
Living things need a constant supply of energy. The sun provides that energy, which is transformed into food by plants through photosynthesis.
Herbivores (plant-eating animals) eat the plants and receive energy. When the herbivore is eaten by a carnivore (an animal that eats herbivores), the energy from the herbivore is transferred to the carnivore. The transfer of energy from one organism to another makes up a food chain.
