…is the theme of this years’ Royal Society of Biology amateur photography competition. The competition invites photographers to explore interactions between the macro and the micro in biology – from tiny fish creating huge shoals, to algal blooms suffocating a river ecosystem, or microorganisms eating plastic waste in our oceans.
Supported by Eppendorf, the competition has two categories each with a cash prize: 18+ (£1000) and under 18s (£500).
Get snapping and submit up to three images by 31st August 2016. Find out more online.
