A stable ecosystem is characterized by having a continual input of energy from the sun. This is required in order to sustain or maintain a stable structure. Without proper supply of energy, life would not exist. Hope this answers the question.

What are convergent boundaries?

boyakko [2]

Answer:

Explanation:

A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.[1] These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types.

Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surface to the mantle.[2] These convection cells bring hot mantle material to the surface along spreading centers creating new crust. As this new crust is pushed away from the spreading center by the formation of newer crust, it cools, thins, and becomes denser. Subduction begins when this dense crust converges with less dense crust. The force of gravity helps drive the subducting slab into the mantle.[3] As the relatively cool subducting slab sinks deeper into the mantle, it is heated, causing hydrous minerals to break down. This releases water into the hotter asthenosphere, which leads to partial melting of asthenosphere and volcanism. Both dehydration and partial melting occurs along the 1,000 °C (1,830 °F) isotherm, generally at depths of 65 to 130 km (40 to 81 mi).[4][5]

Some lithospheric plates consist of both continental and oceanic lithosphere. In some instances, initial convergence with another plate will destroy oceanic lithosphere, leading to convergence of two continental plates. Neither continental plate will subduct. It is likely that the plate may break along the boundary of continental and oceanic crust. Seismic tomography reveals pieces of lithosphere that have broken off during convergence

Homologous structure are body parts that are similar to each other. They are almost the same, but not quite. That's how the meanings are similar.

When you see the glycerinated muscle fibers shorten, what do you think is actually happening in the muscle cells? think about wh

madam [21]

I believe that you are supposed to notice that the striations in the contracted muscle fibers are much closer together than the striations in the uncontracted muscle. Therefore, it would appear that somehow the striated parts of the muscle are being pulled closer together somehow. Glycerinated muscle retains the organized structural array of myosin thick filaments and actin thin filaments, actin associated proteins like troponin and tropomyosin which regulate contraction, and the functional capacity for contraction.
