Task 4
Phoresy is a relationship between two species. One species can’t transport themselves, so they use another species to transport them without causing any injuries. The professor uses the example of mites and hummingbirds to explain it. Mites are small insect-like animals, they feed on nectar and pollen in flowers. But tropical flowers wilt quickly, mites need to find another flower to eat quickly too. Mites are too small, and they can’t fly, so it takes a long time for them to climb down and up a new flower. They choose the hummingbirds as the helper. Hummingbirds also feed on nectar. So when the hummingbird comes and sticks its beak into the flower, the mites quickly climb onto it. Because mites are tiny, so the bird isn’t harmed. They just stick to the hummingbird, when the bird goes from flower to flower, it takes the mites along. When the bird gets to the next flower, the mites climb off and eat in the new flower.
