They share different ecological relationships, one of them being symbiosis.
The other is not helped, but it is not harmed or damaged from the relationship either.
The mutually beneficial relationship between algae and modern corals — which provides algae with shelter, gives coral reefs their colors and supplies both organisms with nutrients — began more than 210 million years ago, according to a new study by an international team of scientists including researchers from Princeton University.
Adaptive quickly gave rise to many diverse groups of plants, and, at the same time, corresponding speciation occurred in certain insect groups.
Amensalism is a non-symbiotic, asymmetric interaction where one species is harmed or killed by the other, and one is unaffected by the other.
