Answer:
Bathypelagic Zone
Explanation:
This zone occurs above the Abyssopelagic zone and below the Mesopelagic zone. The zone is dark because little light reached this region. Only a small proportion of the higher frequency visible light (red light)reaches this region. The sea creatures in this region will be predominantly back or red in color.
Hope this helps!
A collision of two galaxies has left a merged star system with an unusual appearance as well as bizarre internal motions. Messier 64 (M64) has a spectacular dark band of absorbing dust in front of the galaxy's bright nucleus, giving rise to its nicknames of the "Black Eye" or "Evil Eye" galaxy.
Fine details of the dark band are revealed in this image of the central portion of M64 obtained with the Hubble Space Telescope. M64 is well known among amateur astronomers because of its appearance in small telescopes. It was first cataloged in the 18th century by the French astronomer Messier. Located in the northern constellation Coma Berenices, M64 resides roughly 17 million light-years from Earth.

An individual's major depressive disorder is most likely to be characterized by a constant sense of melancholy or a lack of interest in external stimuli.
<h3>What is depressive disorder?</h3>
Depressive disorder is a mood disorder characterized by persistent sorrow and loss of interest. Clinical depression, often referred to as major depressive disorder, has an impact on your emotions, thoughts, and behavior and can result in a variety of mental and physical problems. You could periodically feel like life isn't worth living and find it difficult to go about your everyday chores.
You can't suddenly "snap out" of depression; it's more complicated than a bout of the blues. Depression could require long-term therapy. However, don't give up. The majority of depressed people experience less severe symptoms thanks to medication, counseling, or both.

<span>The delineation of an aquatic ecosystem is the process of spatial identification, mapping and recording of the site; description documents the critical components and processes that underpin the ecosystem values of the site, and develops conceptual model(s) and identifies threats.
Delineating an aquatic ecosystem often starts with defining the main aquatic elements (core elements). The core elements will often be distinct landforms or features such as a waterhole, a swamp, a lake or a river. Ecotonal areas may be included as part of the core element or may be considered as a separate zone. For example, riparian vegetation is often considered to be an integral part of a river ecosystem, even if only inundated in big flood events.
The area around the core elements that has a critical influence on ecosystem function is referred to here as the Ecological Focal Zone. Beyond this, the landscape may be usefully differentiated as a Zone of Influence and a Catchment Zone.</span>
