Answer:
Micro: A small scale ecosystem such as a pond, puddle, tree trunk, under a rock etc. Messo: A medium scale ecosystem such as a forest or a large lake.
Explanation:
Step-by- step Explanation:
- Since the percentge is gradually decreasing a point will come when it will be Zero. Therefore number of trophic level is limited and typically less than 10.
- If we properly look at the pattern 100%>10%>1%>0.1%. We observe that, only ten percent of available energy is transferred from one trophic level to the next.
- Now, if we look at the structure of the model, The box representing the primary consumer is larger than the boxes representing other consumers Thus, we can conclude that, Among the consumers in the ecosystem, first level consumer have the most available energy.
Thus , sclaims B,C and D supported by the model.

The right option is; slab-pull
The main source of downward convection flow in the mantle is called slab pull.
Slab-pull is the force applied by a cold, dense oceanic plate descending into the mantle as a result of its own weight. This process is known as subduction. The oceanic plate has a density higher than that of the hotter mantle below it and the difference in their density causes the plate to submerge into the mantle.
