While planning a presentation, a student takes the following notes:
- Giant kelp (*Macrocystis pyrifera*) forms dense underwater forests in cool, shallow ocean waters.
- These forests provide food and shelter for thousands of marine species.
- Kelp forests also protect coastlines by absorbing wave energy.
- Marine biologist Dr. Elena Vance studied these kelp forests in 2023.
The student wants to present a generalization about giant kelp forests. Which choice most effectively uses information from the given notes to accomplish this goal?
- Giant kelp forests serve as vital habitats for thousands of marine species and shield coastlines by absorbing wave energy.Answer
- BDr. Elena Vance studied giant kelp forests in 2023, focusing on how they grow in cool, shallow ocean waters.
- CGiant kelp forests are the most crucial ocean habitats on Earth because they support all marine species and prevent all coastal erosion.
- DGiant kelp forests protect coastlines by absorbing wave energy, but they do not provide food or shelter for marine species.
Answer
The option stating that giant kelp forests serve as vital habitats for thousands of marine species and shield coastlines by absorbing wave energy.
The correct option effectively uses information from the notes to present a generalization about giant kelp forests. It accurately summarizes their main functions: acting as a habitat (providing food and shelter) and protecting the coastline (by absorbing wave energy).
