Grade 6 Reading Comprehension Worksheet – Mangroves

Let's go through the passage and answer each question step by step based on the information provided.

#### Passage Summary:
Mangroves are large shrub-like plants found in tropical and sub-tropical coastal areas. They thrive in salty seawater where most other land plants cannot survive. They form dense forests along shorelines and have special adaptations such as salt-filtering roots and salt-excreting leaves. Their complex root systems provide habitats for marine life, help build sediments, and support biodiversity. Belize has the highest percentage of mangrove cover in Central America, with about 3.4% of its territory covered by mangroves (184,548 acres), according to a 2010 satellite study by the World Wildlife Fund.

Answers to Questions:

---

1. What are the mangroves and where do they cultivate?

- Answer: Mangroves are large shrub-like plants that grow in tropical and sub-tropical coastal regions. They are typically found along shorelines in areas with saline (salty) water.

- Explanation: The passage states that "Many tropical and sub-tropical shores are home to...mangroves," meaning they naturally grow in these warm coastal zones.

---

2. How do mangroves form?

- Answer: Mangroves form dense, submerged forests along shorelines due to their ability to survive in salty seawater. They grow in clusters and develop complex root systems that stabilize the soil and allow them to thrive in tidal zones.

- Explanation: The text says mangroves "tend to form dense, submerged 'forests' along shorelines" because of their adaptation to saltwater environments.

---

3. Do mangroves have adaptive ability?

- Answer: Yes, mangroves have strong adaptive abilities. They can survive in seawater that is too salty for other land plants by filtering out salt through their roots and excreting excess salt through their leaves.

- Explanation: The passage mentions that mangroves achieve survival in salty water “through salt and leaves that excrete it into the water,” showing their specialized adaptations.

4. How do mangrove root systems serve as a nursery?

- Answer: Mangrove root systems provide shelter and protection for young marine animals like fish and crustaceans. These roots create a safe environment where marine life can grow before moving into open waters.

- Explanation: The passage says their “complex root systems serve as nursery habitats for marine life,” indicating they act as natural nurseries.

5. Which Central American country covers the highest area with mangrove?

- Answer: Belize covers the highest area with mangrove in Central America.

- Explanation: The passage clearly states: "The nation of Belize features the highest overall percentage of forest cover of any of the Central American countries, its mangrove cover."

---

6. What was the study of World Wildlife Fund about the mangrove?

- Answer: The World Wildlife Fund conducted a 2010 satellite-based study of Belize’s mangroves, which found that mangroves cover 184,548 acres—equivalent to 3.4% of Belize’s total territory.

- Explanation: This is directly stated in the last sentence of the passage: "A 2010 satellite-based study of Belize’s mangroves by the World Wildlife Fund observed that mangrove spread over 184,548 acres..."

✔ Final Answers:

1. Mangroves are large shrub-like plants found in tropical and sub-tropical coastal areas, especially along shorelines in salty water.

2. They form dense, submerged forests along coastlines due to their ability to survive in saltwater.

3. Yes, they have adaptive abilities like filtering salt and excreting it through leaves.

4. Their complex root systems provide shelter and habitat for young marine life, acting as nurseries.

5. Belize has the highest mangrove coverage in Central America.

6. The World Wildlife Fund’s 2010 satellite study found that mangroves in Belize cover 184,548 acres (3.4% of the country).
