This achievement standard involves the description of animal behaviour and plant responses in relation to environmental factors.

Animal behaviour and plant responses will be selected from those relating to:

• orientation (tropisms, nastic responses, taxes, kineses, homing, migration)
• timing (annual, daily, lunar, tidal)
• interspecific relationships (predation, parasitism, mutualism, commensalism, competition for resources)
• intraspecific relationships (territoriality, cooperative interactions, reproductive behaviours, hierarchical behaviour, competition for resources).

The relationship of environmental factors to behaviour/response may be in terms of the process involved or the adaptive significance.
