Answer:
Ventral
Explanation:
This is because when you want to dissect a pig, it's back is place on a dissecting tray and it's belly side is up which is the ventral side. With the ventral side, dissection will be easy and the major organs and systems can be observed easily as they will be rightly viewed because they are obvious and rightly placed at belly side up.
The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.
<h3>
How do materials move within the earth?</h3>
The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.
So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

Energy moves from one trophic level to another as organisms feed on one another.
Explanation:
Energy flows from one trophic level to another in a food chain. according to the ten percent law, only ten percent of the total energy passes onto the next trophic level. While studying the energy flow model two aspects should be taken under consideration. Firstly, the flow of energy is unidirectional and passes on from autotrophs to primary consumer and then secontary, tertiary so on. Secondly the amount of energy decreases at succesive trophic level.
