Roles of Organisms Organisms can be either producers or consumers in terms of energy flow through an ecosystem.Producers convert energy from the environment into carbon bonds, such as those found in the sugar glucose. Plants are the most obvious examples of producers;plants take energy from sunlight and use it to convert carbon dioxide into glucose (or other sugars). 11

Primary Producers ·Primary producers, such as plants,algae, and many bacteria, convert light energy from the sun into "food"energy C Thomas Schopke 12
12 Primary Producers • Primary producers, such as plants, algae, and many bacteria, convert light energy from the sun into “food ” energy
Consumers ·Consumers cannot make their own food ·Consumers include herbivores,carnivores, and omnivores ·Less energy is available at each successive level of thethe food chain 13
13 Consumers • Consumers cannot make their own food • Consumers include herbivores, carnivores, and omnivores • Less energy is available at each successive level of the the food chain
Decomposers ·Decomposers such as bacteria and fungi break down organic matter which allows the cycling of nutrients back into the environment 14
