Changes in Biodiversity

Producers are also known as autotrophs. In our utopia, the brown algae, hawthorn trees, and Johnson grass are the producers.  They use light energy or energy stored in chemical compounds to make energy-rich compounds in a process called photosynthesis.  All the other organisms - the red foxes, cottontail rabbits, red-tailed hawks, rattlesnakes, screech owls, locust grasshoppers, brown bears, rainbow trout, roe deer, harpy eagles, flying squirrels, vineyard snails, and earthworms are all dependent on the producers.  The hawthorn trees, johnson grass, and brown algae all make their own food and nutrients by using inorganic substances.
 
Decomposers are organisms that break down complex compounds of the dead and decaying animals and plants in our environment into simpler molecules that can be more easily absorbed by other members in the ecosystem.  Our decomposers are vineyard snails, cyanobacteria, actinolites(a type of bacteria) and earthworms.  They carry out the essential process if nutrient recycling.  When the vineyard snails, cyanobacteria, actinolites, and earthworms break down the dead plants and animals in the forest, other organisms in the ecosystem can use the molecules of energy.  Decomposers are a vital part of the ecosystem.
