Coral reefs are home to many marine life so you know its not predation because the coral can't eat any fish. There are no competition between coral reefs they play the same part so yea. The only good answer is symbiosis. The definition of Symbiosis is <u>interaction between two different organisms living in close physical association, typically to the advantage of both</u>
Symbiotic relationships in nature means that two organisms help each other. Coral reefs are poisonous to most sea life EXCEPT the clownfish, which uses the coral as homes. The clownfish also provide food for the coral, so both benefit.
To solve the question we proceed as follows; time=distance/speed distance between the monkeys is 2km=2000m But the speed of sound= 330 m/s Therefore the time taken for a howler monkey to get to the other will be: time=2000/330 =6.1 seconds The answer is 6.1 seconds
