Seagrass meadows are vital marine ecosystems, but they are rapidly declining worldwide due to coastal development and pollution. In response to this ecological crisis, conservationists have historically relied on transplanting mature seagrass shoots from healthy beds, a method that often damages the donor sites. Recently, however, marine biologist Dr. Elena Vance proposed a novel restoration technique: using biodegradable mesh mats embedded with seagrass seeds. Vance's team tested these mats in degraded bays and found that they successfully stabilized the seafloor and allowed new shoots to propagate without harming existing meadows, offering a promising, low-impact solution for marine restoration.
Which choice best describes the overall structure of the text?
- AIt outlines the chronological history of seagrass decline, compares the biological traits of different seagrass species, and predicts their future survival rates.
- BIt details the physical design of biodegradable mesh mats and explains the chemical process of seed embedding.
- It identifies an environmental problem, explains a drawback of a traditional response to that problem, introduces an alternative method, and presents evidence of that method's effectiveness.Cevap
- DIt refutes the idea that seagrass meadows are declining, asserts that coastal development has no impact on marine habitats, and recommends expanding donor sites.
