AND FOOD WEBS Interactions are the relationships that organisms have within an ecosystem These relationships are usually defined by the organisms niche   These interactions form food chains and food webs. carnivores. A carnivore is an animal that gets food from . killing . carnivores have to hunt down and kill other animals they require a large amount of calories. This means that they have to eat many other animals over the course of the year. The bigger the carnivore, the more it has to eat.

The . trophic level . of an organism . indicates the position. that the organism occupies in the food chain—what it eats and what eats it. . Energy Transfer. Energy transfers from one organism to another when they are consumed and metabolized.. Energy can be followed based on how organism obtain energy.. Trophic levels . – the position of an organism in a sequence of energy transfer. Source of Energy. Raise your hand if you included this on your schoolyard diagram. . The Sun provides the light and heat energy for most forms of life on Earth.. Sun = Sol. Producers.
