The largest seaweed is two to three hundred meters long, making it the longest living thing on Earth

The largest seaweed is two to three hundred meters long, making it the longest living thing on Earth. The explanatory technique of "column numbers" is used.

In the example sentence, the length of the largest seaweed is indicated by a length of two or three hundred meters. The method of using column numbers can quantitatively explain the characteristics of things or the way of things, making the statement more accurate, more scientific, more specific and more convincing.

It should be noted that the figures quoted must be accurate, inaccurate figures must never be used, and even estimated figures need to have a reliable basis.

Example sentences: 1. The bridge is 265 meters long and consists of 11 semicircular stone arches, each of which is of different lengths, from 16 meters to 21 6 meters. The bridge is about 8 meters wide and has a flat surface, almost parallel to the river.

2, Yue Yu stele high meters, wide meters, the inscription is divided into 9 lines, 9 words per line, 77 words, the last line of empty four words.

3. There are more than 200 large and small harbor forks in the lake, more than 50 peninsulas, and the backwater is 10 kilometers long.

4. China once found a whale weighing nearly 40,000 kilograms, about 17 meters long, and a tongue is as heavy as a dozen big fat pigs.

5. Cod spawn up to 10 million eggs at a time, and less than 1% of the eggs that actually become juveniles may be less than 1%.

6. In this way, the lake area in the middle and lower reaches of the Yangtze River was still more than 22,000 square kilometers in the 50s of the 20th century, and only left in the 80s of the 20th century.

12,000 square kilometers, reduced.

Illustrative methods such as giving examples, making comparisons, and listing figures are used. In the introduction of the plants under the sea, you can appreciate the beauty of the underwater world.

This sentence comes from the text "The Underwater World", which introduces the underwater world from four aspects: the sound of the seabed, the activity characteristics of the animals on the seabed, the differences of plants on the seabed, and the topography of the seabed.

How to explain the column numbers.

The method of explaining the number of words in columns is used.

There are two theories on this issue:

1.Some say that the longest seaweed is two or three hundred meters long, making it the longest creature on earth.

2.Some say that a vine plant in the rainforest is the longest living thing on earth, reaching more than 400 meters.

Dear, I'm glad to answer your <>

Microalgae in the ocean can photosynthesize very efficiently. It is the process of synthesizing organic matter using light energy, carbon dioxide and water. Specifically, microalgae in the ocean can:

1.Efficient absorption of light energy, especially blue and red light. Microalgae contain large amounts of photosynthetic pigments, such as chlorophyll and other carotenoids, which can absorb the available spectrum in water.

2.Efficient CO2 fixation. Microalgae can quickly absorb carbon dioxide from water and convert it into organic compounds.

3.Oxygen is produced. A by-product of photosynthesis is the production of oxygen.

The oxygen produced by marine microalgae is essential for sustaining other organisms in the ocean. 4.Grows and reproduces rapidly.

Many marine microalgae grow and multiply quickly and can multiply rapidly in a short eggplant beam time, which favors their rapid use of light and nutrients. 5.Produces abundant biomass.

Due to the high efficiency of photosynthesis, the biomass of marine microalgae is also high, which provides the basis for the marine food chain. So in conclusion, microalgae in the ocean are efficient because they are efficient in photosynthesis and produce a lot of oxygen and biomass in the process, which provides the basis for the entire marine ecosystem.

Microalgae in the ocean can carry out photosynthesis efficiently.

Photosynthesis is the process by which microalgae synthesize organic matter by using solar energy, requiring conditions including water, light, and carbon dioxide. The abundance of microalgae in the oceans is abundant, and the microbiome in the surface water column is mainly composed of microalgae, which are one of the most important marine organisms associated with photosynthesis.

Microscopic algae in the ocean usually exist in the form of planktonic cells, which can absorb carbon dioxide from water and absorb and utilize sunlight through cell membranes, so as to carry out efficient photosynthesis and produce abundant organic matter.

In addition, microalgae can also be mixed in water bodies to maintain the balance and stability of marine ecosystems by jointly managing abundant organic matter, utilizing the dissolved oxygen produced and depleting toxic and harmful substances in the bottom water bodies.

Therefore, the microalgae in the ocean are an important part of the marine ecosystem. It has an efficient photosynthetic capacity and is able to produce abundant organic matter, which plays a vital role in the growth and development of marine life.

Algae

Algae are a class of simple plants that grow in water or humid environments, they photosynthesize like other plants, using light energy to convert carbon dioxide and water into oxygen and energy-rich organic matter, while also absorbing some inorganic matter and nutrients.

Algae are diverse in species and morphology, ranging from unicellular to multicellular, ranging in size from a few microns to several meters; There are species that can live in symbiosis with fungi to form moss-like organisms, and there are species that can form large amounts of algal blooms in water.

Algae are an important part of ecosystems, they are the bottom of the marine food chain and important producers of freshwater bodies, playing a vital role in the material cycle and energy flow of ecosystems.
