Empathy for bees. Some blossoms are forming and some are falling apart. The newest blossoms are too new to provide pollen and the oldest blossoms have fallen apart. The middle two blossoms are the right growth to pollinate each other. How does this work with bees? How do the bees know when to pollinate? Humans can look at the pistil and tell by length of pistil and stickiness of pollen. Bees are attracted to the nectar released only at this time. While eating the nectar, the bee collects and carries the pollen to the other flowers that are also providing nectar. Nectar in common signals and motivates the bees to pollinate the plant. Two different species with two different evolutionary tracks, one a plant the other an animal, and yet they cannot live without each other. Symbiosis from Greek σύν "together" and βίωσις "living".
