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.
