ECOSYSTEMS
132 Every distinct part of
nature’s works is
necessary for the
support of the rest

134 All organisms are
potential sources of food
for other organisms
The ecosystem
138 Life is supported by a vast
network of processes
Energy flow through
ecosystems
140 The world is green
Trophic cascades
144 Islands are ecological
systems

numbers that matters
Ecological resilience

biodiversity
153 Only a community
of researchers has a
chance of revealing
the complex whole
Big ecology
154 The best strategy
depends on what
others are doing

microscopes nothing
escapes our inquiry
The microbiological
environment
86 If you do not know
