How It Works

WHICH POLLINATIO­N TECHNIQUE IS BEST: ABIOTIC OR BIOTIC?

- Pete Morris

If a flower pollinates without the help of an organism, it’s an abiotic pollinator, but if it pollinates with their help it’s a biotic pollinator. Of all of Earth’s flowers, only 20 per cent are abiotic – 98 per cent of which use wind to achieve pollinatio­n. Statistica­lly, it’s harder to reproduce in this way due to increased points of failure and dependence on weather, proximity and so on.

The other 80 per cent of plants are biotic pollinator­s, relying mainly on insects and birds to carry their pollen from one plant to another. This system is statistica­lly more successful, with plants, birds and insects often co-evolving to unconsciou­sly get the best for each other. The plants get pollinated while the organisms get energy from the nectar.
