For Ms. Musich’s Sixth Grade Class Food Chains and food webs
Energy Roles • Producer • Obtains energy through photosynthesis • All plants • Consumer • Obtains energy by eating plants or animals • All animals • Decomposer • Obtains energy by decomposing the dead remains of organisms • Fungi & Bacteria
Producer • All food chains begin with a producer
1st Level Consumer • A 1st level consumer eats the producer • These consumers are known as herbivores • Herbivores are animals that only eat plants
2nd Level Consumer • A 2nd level consumer eats the first level consumer • These consumers could be considered omnivores or carnivores • An omnivore is an animal that eats both plants and animals • A carnivore is an animal that only eats meat
3rd Level Consumer • A 3rd level consumer eats a 2nd level consumer • These consumers can be considered carnivores • A carnivore is an animal that only eats meat
Scavengers • A scavenger is an animal that doesn’t hunt for food. • They “scrounge” for food that other animals have killed. • Some common examples are crows, hyenas, vultures and raccoons Decomposers and Scavengers are VERY important parts of an ecosystem! Why?
Decomposers and Scavengers are VERY important parts of an ecosystem! Why?
Fungi is pretty! http://lamington.nrsm.uq.edu.au/documents/plant/fungi.htm
Without Decomposers/Scavengers… We would be living with a lot of trash…
What Do Food Chains Show Us? • A food chain shows how each organism obtains food. • How nutrients and energy are passed from creature to creature. An example of a food chain with 3 organisms
More Examples 1st Level Consumer 2nd Level Consumer 3rd Level Consumer Producer 1st Level Consumer 2nd Level Consumer 3rd Level Consumer 4th Level Consumer Producer
For Homework! • Create three separate food chains! • Remember, they must start with a producer! • Each chain must be at least 4 organisms long. • COLORING IS NOT OPTIONAL - YOU MUST.
Food Webs • A food web is just a bunch of food chains put together! W E B C H A I N
Energy Pyramid • An energy pyramid shows the amount of energy transferred from one level to the next.
