Chapter 9 Flashcards - Habitats, environment and survival.
The survival of organisms, and therefor their distribuition and abundance, depends on both biotic (living) and abiotic (physical) factors.
Draw up two columns, headed biotic and abiotic, and list as many factors you can think of that fit into these categories.

Adaptations for survival can be structural (how an organism is built), functional (physiological adaptations) or behavioural (how an organism acts).
