Because it is too dark for photosynthesis to occur at these depths
Plant photosynthesis is the primary source of nutrients in every ecosystem. Deep in the ocean, where little or no sunlight is present, photosynthesis is impossible. Thus, organisms in deep water ecosystems depend on detritus (discarded waste) and other organic matter that drifts down from (and is generated) nearer to the surface, or on species that migrate back and forth.
The depth at which dangerous pressure levels are encountered underwater varies depending on factors such as the individual's health and diving experience. However, in general, dangerous pressure levels can start to be experienced at depths greater than 30 meters (approximately 100 feet). It is important for divers to be properly trained and equipped to handle the increased pressure at greater depths.
No, plantlike organisms generally require sunlight for photosynthesis, which is limited below 1000 meters in the ocean. Below this depth, the lack of light makes it challenging for plantlike organisms to survive and thrive due to the limited energy available for photosynthesis.
Deep-sea creatures live under water in an ocean or sea. They live in deapts such as trinches or caves. They are atleast 40 to 50 miles under water.' +++ There no "caves" in the deep oceans. You find them in shallow coastal seas and coral reefs. The oceans are NOT "40 to 50 miles" deep - those figures are rubbish. The mean depth of the abyssal plains is about 3-4 miles at most; some subduction trenches like the Marianas are deeper, but none reach even 10 miles.
Crinoids, also known as sea lilies, are marine organisms that typically range in size from a few centimeters to several meters in length. On average, crinoids are smaller in size compared to other marine organisms such as whales, sharks, and large fish.
Marine algae require sunlight for photosynthesis, which is the process that provides them with energy. Light penetration decreases with depth, leading to insufficient light for photosynthesis beyond 200 meters. This absence of marine algae at depths below 200 meters can limit the availability of food and oxygen for other marine organisms, impacting the overall biodiversity and food web dynamics in these deep-sea ecosystems.
Bioluminescent organisms are found mainly in the mesopelagic zone of the ocean, also known as the twilight zone. This zone is located between the surface and the deep sea, typically between depths of 200 to 1000 meters, where very little sunlight penetrates. Bioluminescence is an important adaptation for organisms in this area to communicate, camouflage, or attract prey.

The bathyal zone is a deep-sea region typically found at depths of 200 to 4,000 meters. It receives little to no sunlight, resulting in low light levels. Organisms in this zone are adapted to withstand high pressure and cold temperatures.

Yes, 5 meters underwater is generally considered scuba diving. Scuba diving typically involves using a self-contained underwater breathing apparatus to explore underwater environments at various depths. While recreational diving can occur at varying depths, 5 meters is within the range commonly accessed by divers.
The depth of seas bordering continents can vary greatly, with some reaching depths of over 12,000 feet (3,660 meters) or more. For example, the Java Trench in the Indian Ocean reaches depths of around 24,442 feet (7,450 meters). These deep trenches are formed by tectonic plate movements and are some of the deepest parts of the Earth's oceans.
The porpoise can dive to depths of 200 meters. However, they tend to stay in shallow coastal regions to hunt.

Bass Strait has an average depth of around 50 meters (164 feet) but can reach depths of up to 245 meters (804 feet) in some areas.
The deepest regions of the sea, with depths greater than 6,000 meters, are known as the abyssal zone. This zone is characterized by extreme pressure, cold temperatures, and complete darkness, making it one of the most challenging environments on Earth. It is home to unique organisms adapted to its harsh conditions, including various species of deep-sea fish, invertebrates, and bacteria.
