The Sun
• Definition: A flaming ball of hot gas that gives off heat and energy.
• Characteristics: abiotic, hot, gives off light energy, star, helps plants produce food
• Illustration: Draw a picture of the sun

Producer
• Definition: An organism that can make it’s own food.
• Characteristics: autotroph-can carry out photosynthesis, biotic, source of all the food in an ecosystem
• Examples: grass, oak tree, flowers, other plants
• Illustration: Draw a picture of a tree

Consumer
• Definition: An organism that obtains energy by feeding on other organisms.
• Characteristics:
• heterotroph- depend on producers for food and energy
• Herbivores- eat only plants
• Carnivores- eat only meat
• Omnivores- eats both plants and animals
