 Can be as small as a
single celled
bacteria


Or as large as a
whale!
Categories of Feeding
Relationships
1)
Producers
2)
Consumers
3)
Decomposers
4)
Detritivores
5)
Scavengers
They are all depend on each other.
Primary Producers

organisms that use energy to make food .
(PLANTS)

Process is photosynthesis

Equation: CO2 + water -
C6H12O6 + O2

Or from chemicals –
- Chemosynthesis
– uranium,
arsenic, sulfur, nitrogen
Autotrophs

Term for primary producers- Auto –
a prefix meaning oneself

Trophic- relating to food or
nutrition

Can make their own food and use it
for energy to power themselves.
Consumers

Consumers need to eat their food
to get energy. (ANIMALS)
Types of consumers are

There are THREE types of Consumers

Carnivores

Herbivores

Omnivores.

Scavenger

Detritivor and Decomposer

Its still all about what you eat!

Heterotrophs –

Hetero- other / troph- feeding.
Carnivores only eat meat (other
animals)
Herbivores eat only plants.
Omnivores eat both meat (animals) and
plants.
Decomposers and Detritivore

Decomposers an organism that
chemically break down the cells of
dead plants and animals into simpler
substances.

-releases organic nutrients to the
ecosystem

Examples:

Mushrooms

Bacteria
Detritivores

an animal that feeds on dead organic material,
especially plant detritus.

Similar to decomposers

Examples – fungus, bacteria, worms, many other
invertebrates.
What would the world look like
without decomposers (bacteria and
fungi?
