Question

Почему в океане на больших глубинах обитают только животные? ПОМОГИТЕ!!!!!!!ОЧЕНЬ СРОЧНО!!!!ЗАВТРА СДАВАТЬ!!!

Answer 1

Растения не живут на больших глубинах, так как без солнечного света невозможен синтез углеводов (фотосинтез) .
А животные (в том числе рыбы) могут, т. к потребляют уже готовую биомассу.
Также на дне обитает множество бактерий, разлагающих организмы до неорганических веществ.

Answer 2

Why do only animals inhabit the deep depths of the ocean?

The deep depths of the ocean are home to a variety of animals, but why is it that only animals inhabit these areas? There are several reasons for this phenomenon.

1. Lack of sunlight: One of the main reasons why only animals inhabit the deep depths of the ocean is the lack of sunlight. Sunlight is crucial for photosynthesis, the process by which plants and algae convert sunlight into energy. Without sunlight, plants and algae cannot survive, and as a result, the deep depths of the ocean are devoid of plant life.

2. Extreme pressure: Another factor that limits the presence of organisms in the deep ocean is the extreme pressure. The pressure at great depths can be several hundred times greater than at the surface. This high pressure can be detrimental to many organisms, as it can disrupt their bodily functions and cause damage to their cells.

3. Cold temperatures: The deep ocean is also characterized by cold temperatures. Water temperature decreases with depth, and in the deep ocean, temperatures can be near freezing. These cold temperatures can pose challenges for organisms, as they can slow down metabolic processes and limit the availability of energy.

4. Limited food supply: The deep ocean has a limited food supply compared to the surface waters. Sunlight-driven photosynthesis, which forms the base of the food chain in the surface waters, is absent in the deep ocean. As a result, the food web in the deep ocean relies on organic matter that sinks from the surface or is produced by chemosynthetic bacteria near hydrothermal vents.

Despite these challenges, many animals have adapted to survive in the deep ocean. These animals often have specialized adaptations that allow them to withstand the extreme conditions, such as bioluminescence for communication and camouflage, large mouths for capturing prey, and efficient energy storage mechanisms.

In conclusion, the lack of sunlight, extreme pressure, cold temperatures, and limited food supply are some of the reasons why only animals inhabit the deep depths of the ocean. These animals have evolved unique adaptations to survive in this harsh environment.
