Ecology is the study of the interrelationships between organisms and their environment. An Introduction to Ecology and Population Biology, 1973.

 

. . . ecology is probably the most complex and least understood area of biology today, while being the biological discipline most important and relevant to the future of our world. Ibid.

 

The niche includes the species' physical habitat (the place where the organisms live) and adaptive strategy (how the species acquires energy and makes it living). Ibid.

 

A food chain simply transfers food energy from a given source through a series of species, each of which eats the one before itself in the chain. Ibid.

 

The root of almost all the threats to natural communities and the ecology of our earth is the explosive growth of the human population. Ibid.
