ENERGY AND LIFE Objective: Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?
ALL LIVING THINGS NEED Energy TO SURVIVE
SUNLIGHT is the source of energy for almost all living things
On a Post It note: • Write: P = C= D= Write examples of plants/animals that are producers, consumers, and decomposers.
1. Producers Organisms that use sunlight directly to make food • They do this by a process called PHOTOSYNTHESIS • Also known as Autotrophs – organisms that can make their own food!
PRODUCER EXAMPLES: Grass, Plants, Trees Corn
Biomass • Producers create Biomass – the mass of matter produced by organisms in an ecosystem. • More Glucose produced = Increase Biomass • Glucose contains potential energy
2. Consumers Organisms that eat producers or other organisms for energy! • Also known as Heterotrophs – organisms that cannot make their own food and must eat other organisms!
There are 4 Types of Consumers: Herbivores Carnivores Omnivores Scavenger
A. Herbivores Consumer that eats plants
B. Carnivores Consumer that eats animals (meat).
C. Omnivores • A consumer that eats both plants and animals.
Herbivore Carnivore Omnivore Shark Raccoon Koala Fox Deer Hedgehog Snake Chicken Rabbit Tiger Horse Bear Rhino
D. Scavenger Feeds on the bodies of dead animals.
Weird Science • Having survived for 300 million years, the common cockroach may be the most successful and well-adapted scavenger of all time. Cockroaches scavenged dinosaur leftovers long before they survived on the crumbs and kitchen scraps of humans. Dead skin and fingernails are a real treat for them; leftover food is a delicacy. If these tasty morsels aren’t available, cockroaches can survive on such unlikely food sources as shoe polish, paint, and soap.
3.Decomposers Organisms that get energy by breaking down the remains of dead organisms. Known as NATURE’S RECYCLERS and adds nutrients to the soil!
Decomposer Examples: Bacteria and Fungi

Predator:Eat Prey Example: A Lion eats a rabbit. The lion is the predator.
Prey:The organism that is eaten Example: The Lion (predator) eats the Rabbit (prey). The PREY is the Rabbit
Cellular Respiration • Also known as Aerobic Cellular Respiration • You should all know this!
