Ecosystems 11/17/15
An ecosystem is made up of all living organisms (including plants) in a
relatively small area e

a forest or a lake
Chemical Cycling
Energy flow
Carbon and nitrogen are cycled through
Energy enters as sunlight and is converted to
the anabiotic and biotic components of
the ecosystem
...
Energy
and they are then consumed by animals
...
The Conservation of Energy: All ecosystem reactions are controlled by the laws of physics
...
Energy consumption for the organisms can be calculated
by measuring the input (amount of sunlight) to output (heat)
...
Conservation of Mass: mass cannot be created/destroyed
...
Chemical elements cannot escape the ecosystem, hence a cycle

There is a balance between inputs and outputs, however it can be upset by human
activity

The bottom of the food chain
Primary consumers = herbivores
Secondary consumers = carnivores that eat herbivores
Tertiary consumers= omnivores/ carnivores that eat carnivores
Detritivores/Decomposers = consumers that feed on nonliving

Net Primary Production (NPP): amount of energy left in ecosystem after the use of it by primary
producers for respiration (or R)
