They are usually found in deep ocean waters
They can be larger than structures made by people
Knowledge: Reading Comprehension
What is your opinion about coral reefs? ARE NOT right, according to the passage?
A. They are an important source of fish
B. They are one of the most colorful places in the world
C. They are usually found in the deep sea
D. They can be larger than man-made structures
Information: Living coral reefs are remarkable “cities beneath the sea,” filled with a rich variety of life. These shallow oceans thrive in the warm, shallow oceans near the equator
Translated: A living reef is an incredible “undersea city”, filled with abundant life. These marine ecosystems thrive in warm, shallow oceans near the equator.
* So C is not the correct answer
=> Choose the answer C
Coral reefs are some of the most beautiful and diverse ecosystems on Earth, providing habitats for a wide variety of marine life and playing a vital role in the global oceanic food chain. But despite their importance, coral reefs are at risk from a variety of threats, including climate change, overfishing, and water pollution. In order to protect coral reefs and ensure their continued health, it is important to understand the issues facing them.
One common misconception about coral reefs is that they are invincible and can survive any type of environmental stress. This is not true. Coral reefs are incredibly sensitive to changes in their environment, and can suffer from a variety of threats, including rising ocean temperatures, ocean acidification, and pollution. In fact, coral reefs are one of the most vulnerable ecosystems on Earth, and are particularly susceptible to changes in temperature and acidity.
Another misconception about coral reefs is that they are not affected by human activities. This is also not true. Human activities, such as overfishing, pollution, and coastal development, can have a devastating effect on coral reefs. Overfishing can cause a decline in fish populations, which can impact the health of the reef by reducing the amount of food available for the reef’s inhabitants. Pollution can cause a decline in water quality, which can lead to coral bleaching and death. Coastal development, such as dredging and land reclamation projects, can cause sedimentation, which can smother the coral and prevent it from receiving the sunlight it needs to survive.
Finally, it is not true that coral reefs are not affected by climate change. Rising ocean temperatures and ocean acidification, both of which are caused by climate change, can have a devastating effect on coral reefs. Warmer temperatures can cause coral bleaching, while increasing ocean acidity can make it harder for coral to build and maintain its calcium carbonate structure.
In order to protect coral reefs and ensure their continued health, it is important to understand the threats they face and take steps to mitigate them. This includes reducing human activities that can harm coral reefs, such as overfishing and pollution, as well as reducing greenhouse gas emissions to slow the rate of climate change. By taking these steps, we can help protect coral reefs and ensure their continued health for future generations.
