TOEFL Reading Passage:

Perhaps one of the most dramatic and important changes that took place in the Mesozoic era occurred late in that era, among the small organisms that populate the uppermost, sunlit portion of the oceans — the plankton. The term "plankton" is a broad one, designating all of the small plants and animals that float about or weakly propel themselves through the sea. In the late stages of the Mesozoic era, during the Cretaceous period, there was a great expansion of plankton that precipitated skeletons or shells composed of two types of mineral: silica and calcium carbonate. This development radically changed the types of sediments that accumulated on the seafloor, because, while the organic parts of the plankton decayed after the organisms died, their mineralized skeletons often survived and sank to the bottom. For the first time in the Earth's long history, very large quantities of silica skeletons, which would eventually harden into rock, began to pile up in parts of the deep sea. Thick deposits of calcareous ooze made up of the tiny remains of the calcium carbonate-secreting plankton also accumulated as never before. The famous white chalk cliffs of Dover, in the southeast of England, are just one example of the huge quantities of such material that amassed during the Cretaceous period; there are many more. Just why the calcareous plankton were so prolific during the latter part of the Cretaceous period is not fully understood. Such massive amounts of chalky sediments have never since been deposited over a comparable period of time.

The high biological productivity of the Cretaceous oceans also led to ideal conditions for oil accumulation. Oil is formed when organic material trapped in sediments is slowly buried and

Understanding TOEFL Reading on Plankton

As a TOEFL test taker, you may encounter passages related to various scientific topics, including plankton. This article aims to provide insights into how to approach reading materials about plankton effectively, along with some useful tips and practice questions. ??

What are Plankton? ??

Plankton is a term used to describe a diverse group of organisms that live in water and cannot swim against currents. They are crucial for aquatic ecosystems and can be classified into two main categories:

• Phytoplankton: These are microscopic plants that perform photosynthesis and are the primary producers in the ocean. ??
• Zooplankton: These are small animals that feed on phytoplankton and other small organisms.

Key Vocabulary ??

When studying plankton, familiarize yourself with essential terms such as:

• Photosynthesis: The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.
• Ecosystem: A biological community of interacting organisms and their physical environment.
• Biomass: The total mass of organisms in a given area or volume.

Sample Passage ??

Here’s an example passage you might encounter:

"Plankton play a vital role in the marine food web. Phytoplankton, being the primary producers, convert sunlight into energy, forming the base of the food chain. Zooplankton, in turn, consume phytoplankton and serve as food for larger marine animals."

Practice Questions ?

After reading the passage, consider these questions:

1. What role do phytoplankton play in the marine ecosystem?
2. How do zooplankton contribute to the food web?

Listening Practice ??

You may also find listening materials related to plankton. Here’s a sample listening prompt:

"The speaker discusses the importance of plankton in maintaining the balance of marine ecosystems. They highlight how changes in plankton populations can indicate shifts in environmental conditions."

Tips for Success ??

To excel in TOEFL reading sections, especially on topics like plankton, keep the following strategies in mind:

• Skim the Passage: Quickly read through the passage to understand its main ideas before diving into details.
• Highlight Key Information: Use a highlighter to mark important points, such as definitions and examples.
• Practice Regularly: Engage with various reading materials to enhance your comprehension skills.

New Topics to Explore ??

In addition to plankton, consider exploring related topics such as:

• Coral reefs and their ecosystems
• The impact of climate change on marine life
• Ocean acidification and its effects on plankton

Final Thoughts ??

Studying topics like plankton not only helps you prepare for the TOEFL but also enriches your understanding of marine science. By practicing reading and listening skills, you will feel more confident on test day. Good luck! ??
