Brainliest and 5 stars fish, clams, sponges, sharks, and sea turtles are only a few of the thousands of creatures that call coral reefs their home. many of the plants and fish that live in coral reefs depend on one another to live and grow. people also depend on coral reefs. the reefs contain many plants and animals used in medicines, chemicals, or other products we need to lead healthy lives. which sentence supports the argument that humans should protect coral reefs and would make a good concluding sentence to the paragraph? a) because coral reefs count on humans to be created, humans should be able to count on coral reefs too. b) if humans want to go on enjoying the wonders of sea life, they should remember other things besides coral reefs. c) because humans want to fish and scuba dive, we should protect the valuable tourist industry by protecting coral reefs. d) because humans count on the coral reefs and the sealife they support, coral reefs should be able to "count on" humans too.

The health of coral reefs depend on several factors. one is clean water. erosion on land causes rivers to dump mud on reefs, smothering and killing corals. seawater with too many nutrients speeds up the growth of seaweeds and increases the food for predators of corals when they are developing as larvae in the plankton. coral bleaching occurs when coral polyps lose their symbiotic algae. without the algae, the living coral tissues are nearly transparent, and you can see right through to the stony skeleton, which is white, hence the name coral bleaching. many stressors cause coral bleaching: water that is too cold or too hot, too much or too little light, or the dilution of seawater by the input of lots of fresh water. the #1 cause of bleaching today is the rising temperatures caused by global warming. temperatures more than 2 degrees f (or 1 degree c) above the normal seasonal maximimum can cause bleaching. question: fish play an important role in coral reef health as well. all but one effect listed below is the result of the fish populations within the coral reef. a) fish eat predators, such as starfish. b) fish eat seaweed and kelp that could potentially smother the coral. c) some fish live symbiotically with coral, luring in prey for the coral to kill and eat. d) when corals are babies floating in the plankton, fish swim with them and protect them from harm.
