Can be consumed (there may be exceptions)
Can (time range may vary) decompose

Never has and never will live
Can't be consumed (unless artificial)
Has a really hard time decomposing
Food and Water

What Roles do Animals and Plants Fill in an Ecosystem?
Niches: Specific roles that organisms fill in an ecosystem
Producers
Autotrophs: Self feeder
A large and one of the most important niches to exploit in any ecosystem
use energy from the sun and nutrients from the soil to create their own food
They don't consume other organisms so they have to make their own food
Even though they don't need to consume other living things they do require consistent energy
Producers: Algae, Phytoplankton, Chemoautotrophs, most plants, some bacteria and Lichens
Decomposers
A special type of consumer that eats dead things to make energy, by breaking down the things molucules
Also known as Detritivores
Enriches soil with nutrients
Decomposers: Fungi, bacteria, insects and other small animals
Scavengers
Consumers
Require consuming things to make energy
Consumers: Humans, pigs and most living animals
Also known as heterotrophs
Types of Consumers:
Herivores; eat primary producers
Carnavores; eat other animals
Omnivores; eat both meat and vegetables
Not all animals eat just one thing
Roles in an eco - system
Producers
Consumers
Scavengers
Decomposers
There can be an organism that is MORE THAN ONE type
Energy
Need something to change the suns energy to make it useable
Vocabulary
Edaphic: Abiotic factors that relate specifically to soil.
