DESCRIPTION
4 Types of Consumers: 1. Herbivores – consumers that only eat plants = 1st level consumer 2. Omnivores – consumers that eat both plants and animals = 1st, 2nd or 3rd level consumersTRANSCRIPT
Energy Flow*Energy Roles: 1. Producer – an organism that can
make its own food. Examples = plants, algae 2. Consumer – an organism that
must eat other organisms for ENERGY. (4 types)
4 Types of Consumers:1. Herbivores – consumers that only eat
plants = 1st level consumer
2. Omnivores – consumers that
eat both plants and animals =
1st, 2nd or 3rd level consumers
3. Carnivores – consumers that only eat
other animals = 2nd or 3rd level consumers
4. Scavengers – carnivores that eat dead animals =2nd or 3rd level consumers
Examples: Vultures, crabs, catfish
Energy Roles (continued) 3. Decomposers – an organism
that breaks down wastes and dead organisms and returns the raw materials back to the environment.
Examples: Bacteria, molds, fungi (mushrooms)
#4. Food ChainsFood Chain – a series of events in
which one organism eats another to gain ENERGY.
Producer 1st level consumer 2nd level consumer 3rd level consumer.
Shows energy is transferred to next organism.
Tree -> Ant -> Bird -> Cat
Food Webs#5. A food web consists of many
overlapping food chains.
Energy Pyramid
A diagram that shows the amount of energy available to producers and consumers at different levels.
FOOD IS ENERGYEnergy is used to grow, move,
reproduce and other functions.
Energy is used AND lost every time we eat food.
