Phytoplankton are the autotrophs that are the main producers for the upper layers of the ocean.
This is because the upper layers of the ocean provide the most sunlight, which is what phytoplankton need in order to perform photosynthesis.
the first layer is the surface layer it is nice and warm and mixed with the waves. the next layer is the thermocline it is just warm not any thing special. the next is freezing cold i would not want to go there.
The Earth's mantle has two main layers: the upper mantle and the lower mantle. These layers are distinguished by differences in their composition, temperature, and behavior. The upper mantle extends from the crust to a depth of about 410 miles (660 kilometers), while the lower mantle extends from about 410 miles (660 kilometers) to approximately 1,800 miles (2,900 kilometers) below the Earth's surface.
there are 5 major oceans: Arctic, Pacific, Atlantic, Indian, and Southern
Yes, the Earth's crust is typically divided into two main layers: the upper crust and the lower crust. The upper crust is composed primarily of lighter, less dense rocks such as granite, while the lower crust consists of denser rocks like gabbro. This differentiation in composition and density contributes to the overall structure and behavior of the Earth's crust.
While there are more than four oceans on Earth, there are four which are considered the main ones. The four main oceans are the Pacific, Atlantic, Indian, and Arctic.

The mantle is divided into two main layers: the upper mantle and the lower mantle. The upper mantle is further divided into the lithosphere and the asthenosphere. The lithosphere is rigid and made up of the crust and the upper part of the mantle, while the asthenosphere is semi-molten and capable of flowing.
The mantle is divided into two main layers: the upper mantle and the lower mantle. The upper mantle is closer to the Earth's crust and is more rigid, while the lower mantle is hotter and flows more easily due to higher temperatures and pressures.
The 3 main layers of earth (crust, mantle, core) are divided into crust, upper mantle, lower mantle, outer core, and inner core.
