Morphology

irrupt = ir + rupt

Same morphological makeup as sense 1 (ir- + rupt); the ecological sense 'to increase suddenly' is metaphorically related to 'bursting', but because 'rupt' is not a standalone word the relation is only partially transparent to average learners.

Etymology

Irrupt comes from the same idea of 'breaking in' and is like erupt, which means 'to burst out', so picture a species suddenly 'breaking out' across an area. That's why irrupt can mean to increase or appear suddenly and in large numbers.
