The laws of thermodynamics govern the flow of
energy in a system and the ability to do work.
Systems can exist in alternative stable states or as
equilibria between which there are tipping points.

Pyramids of productivity.
The energy flow through a food-chain can be shown in a pyramid of productivity such as:
To draw a good pyramid of productivity, note that:
Do not attempt a 3-D view. It may look pretty, but scientifically is pretty useless!
A species interacts with its abiotic
and biotic environment, and its niche
is describe by these interactions.
Populations change and respond to
interactions with the environment.
