Which of the following organisms lives near the surface of aquatic?

The correct answer is a. Phytoplankton is derived from Greek words “phyto” meaning “plant” and “plankton” meaning “made to drift or wander”. Hence, these are plant like microscopic organisms that live in large water bodies.

Which of the following organisms lives near the surface of aquatic biomes because it needs sunlight to survive a phytoplankton B zooplankton C Sturgeon D manatee?

This is going to be phytoplankton. Phytoplankton need sunlight in order to survive and perform photosynthesis. This is why they stay near the surface of an aquatic biome! =)

What discovery did Alvin make quizlet?

What does the Alvin Do?

Alvin is a 3-person research submersible that takes scientists deep into the ocean. Since its launch in 1964, Alvin has taken more than 14,000 scientists, engineers and observers to visit the floor of the deep sea. They can also use Alvin’s equipment to sample rocks, sediment, fluids, and sea life.

How long can Alvin stay underwater?

ten hours

What makes Alvin the submarine so special?

In the past half century, the deep-sea submersible has made more than 4,700 dives all over the world. It has discovered hydrothermal vents, explored the Titanic, and searched for a missing hydrogen bomb in the Mediterranean Sea. It even spent a year—while lost—at the bottom of the ocean.

What kind of ecosystem was found by Alvin?

Scientists discovered the hot-springs ecosystems with the help of Alvin, the world’s first deep-sea submersible. Constructed in the early 1960s for the U.S. Navy, Alvin is a three-person, self-propelling capsule-like submarine nearly eight meters long.

Who found the Titanic?

Robert Ballard

What is the source of energy for deep sea organisms?

Since the 19th century however, research has demonstrated that significant biodiversity exists in the deep sea. The three main sources of energy and nutrients for deep sea communities are marine snow, whale falls, and chemosynthesis at hydrothermal vents and cold seeps.

What is the source of energy for deep ocean organisms?

The source of energy for deep organisms is the bacterias that take special process called chemosynthesis. These bacterias are called as extremophiles.

What are the names of 3 major ocean basins?

The continents, which cover 29.2% of the earth’s surface, break up the ocean into the three basins, which we call the Atlantic, Pacific, and Indian oceans. The ocean basins, which cover 70.8% of the earth’s surface, can be viewed as northward-projecting gulfs of the world-circling ocean around Antarctica (Fig.

Which algae is found in deep sea?

Red algae

What is the source of light in deep sea?

An intriguing source of light at the very bottom of the sea is found at hydrothermal vents. Here are found not only light but also abundant life. At the vent orifice, temperatures are found to be as high as 250°-400°C. A large component of the light is due to thermal radiation.

Do jellyfish produce light?

Jellyfish such as comb jellies produce bright flashes to startle a predator, others such as siphonophores can produce a chain of light or release thousands of glowing particles into the water as a mimic of small plankton to confuse the predator.

Is jellyfish a source of light?

* Jellyfish are not made of jelly, they are made up of salt, protien and 95% water. Jelly fish light up because they use it as a defense against prodotors. Some jellyfish, such as sea nettles normally make or create their own light. Or they can glow or give off flashes of light as fireflies do.

What is the deepest sea?

Pacific Ocean

What would happen if you were teleported to the bottom of the ocean?

So nothing would happen if you were teleported to the bottom of the Mariana Trench for one nanosecond, although you may come back wet. Light, which travels at just over 186,000 miles per second in a vacuum, only travels about one foot in a nanosecond.

Can water pressure kill you?

The pressure of the water on a deep-diver’s body can crush him. It can easily cause death. Coming up from the extreme pressure of deep water to the much lower pressure at the surface is especially dangerous. Ascending too quickly can cause a fatal condition called “the bends.”

Can you fart while diving?

Farting is possible while scuba diving but not advisable because: An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness. The acoustic wave of the underwater fart explosion can disorient your fellow divers.

Can humans survive 47 meters underwater?

You can you survive 47 metres underwater but to do so you need to have the necessary training and experience as a scuba diver. To survive a deep dive to 47 metres down you must follow decompression stop limits or carry out decompression stops on your ascent to avoid getting decompression sickness.
