PRODUCERS, CONSUMERS, and DECOMPOSERS

1
PRODUCERS, CONSUMERS, and DECOMPOSERS

• Objective
• Can I identify producers, consumers, scavengers,
  and decomposers in a food chain or food web?

2
ALL LIVING THINGS NEED

• Energy
• TO SURVIVE

3
SUNLIGHT

• is the source of energy for almost all living
  things

4
On a Post It note

• Write
• P
• C
• D
• Write examples of plants/animals that are
  producers, consumers, and decomposers.

5
1. Producers

• Organisms that use sunlight directly to make food
• They do this by a process called PHOTOSYNTHESIS

6
PRODUCER EXAMPLES

• Grass, Plants,
• Trees Corn

7
Reality Check

• Can I identify producers, consumers, scavengers,
  and decomposers in a food chain or food web?

8
2. Consumers

• Organisms that eat producers or other organisms
  for energy!

9
There are 4 Types of Consumers

• Herbivores
• Carnivores
• Omnivores
• Scavenger

10
A. Herbivores

• Consumer that eats plants

11
B. Carnivores

• Consumer that
• eats animals (meat).

12
C. Omnivores

• A consumer
• that eats both
• plants and animals.

13
Herbivore Carnivore Omnivore
Shark
Koala
Raccoon
Fox
Deer
Hedgehog
Snake
Rabbit
Tiger
Chicken
Horse
Rhino
Bear
14
D. Scavenger

• Feeds on the bodies of
• dead animals.

15
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 arent available, cockroaches
  can survive on such unlikely food sources as shoe
  polish, paint, and soap.

16
Reality Check

• Can I identify producers, consumers, scavengers,
  and decomposers in a food chain or food web?

17
3.Decomposers

• Organisms that get energy by breaking down the
  remains of dead organisms.
• Known as NATURES RECYCLERS and adds nutrients
  to the soil!

Reality Check

  and decomposers in a food chain or food web?

22
Predator Eat Prey

• Example
• A Lion
• eats a rabbit.
• The lion is the predator.

23
PreyThe organism that is eaten

• Example
• The Lion (predator)
• eats the Rabbit (prey).
• The PREY is
• the Rabbit
