Much as the strands of silk in a spider’s web bind one segment to another, feeding and other interactions bind all organisms to one another.
These complex network of interactions between living things are called the web of life.

Humans Are Part Of The Web Of Life
Humans Are Part Of The Web Of Life
Humans have the greatest impact of any living thing on the web of life
If humans are to continue to thrive on earth, we must understand the interrelationships among all living things and modify our actions.

TERMINOLOGYTERMINOLOGY
Nonliving material within an environment is called abiotic factors.
Living things are called biotic factors.
All the living things in a particular area is called a community.
The community (biotic factors) plus the abiotic factors is called the ecosystem.
