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


Consumer

• Examples:

Humans, sharks, snakes, lions, hawks

• Illustration:

Draw a picture of a consumer


Decomposer

• Definition: Organisms that break down wastes and dead organisms and return the raw materials to the environment.

• Characteristics:

Return simple molecules to the environment

Remove waste and dead organisms


Decomposer

• Examples: Bacteria and fungi, such as mold and mushrooms

• Illustration: Draw a picture of a mushroom


Scavenger

• Definition- a carnivore that feeds on the bodies of dead organisms.

• Examples: Vultures, catfish, ants
