Question

1. what percent of the worlds coral reefs are in indonesia? a. 60% b. 18% c. 7% d. 12% 2. what are some causes of coral bleaching? a. ocean temperatures below freezing, excessive rain and flooding, and deforestation b. many people swimming in the ocean, oil spills from boats, and deep - sea fishing practices c. colder ocean temperatures, fishermen using bleach to poison fish, and regional tsunamis d. warmer ocean temperatures, pollution, deforestation, and destructive fishing practices 3. some fishermen use harmful practices to capture a lot of fish at once. what evidence from the text supports this conclusion? a. “some fishermen use bombs to blast coral reefs and kill large quantities of fish. these bombs also damage the coral reefs. other fishermen use cyanide to poison fish which in turn poisons the coral.” b. “coral and a kind of algae called zooxanthellae have a symbiotic relationship. they each rely on each other to survive. zooxanthellae are the corals primary food source and give the coral its unique color.” c. “rabbits are a great food source for foxes. they eat the algae that grows much faster than coral. rabbits have helped balance the amount of algae and the amount of coral in the reef.” d. “coral reefs are found in tropical and subtropical waters. corals provide a home for many sea creatures but when they die their skeletons create the foundation for new reef growth.”

Explanation:

1. Indonesia es hogar aproximadamente del 18% de los arrecifes de coral del mundo.
2. Las principales causas del blanqueamiento de los corales son las temperaturas marinas más cálidas, la contaminación, la deforestación y las prácticas de pesca destructivas. Las opciones A y C no son correctas porque las temperaturas marinas por debajo del congelamiento no son comunes en áreas de arrecifes de coral y la blanquea usada por pescadores no es una causa común. La opción B no aborda los factores ambientales más importantes.
3. La opción A proporciona evidencia de que algunos pescadores usan bombas para explotar los arrecifes de coral y capturar grandes cantidades de peces, lo que es una práctica dañina.

Answer:

1. B. 18%
2. D. warmer ocean temperatures, pollution, deforestation, and destructive fishing practices
3. A. "Some fishermen use bombs to blast coral reefs and kill large quantities of fish. These bombs also damage the coral reefs. Other fishermen use cyanide to poison fish which in turn poisons the coral."
