Ecological pyramids are graphical representations of the trophic structure of an ecosystem. Regarding these pyramids, check the incorrect alternative.
A) A pyramid is called a number pyramid when it tells you how many individuals there are at each tropic level.
B) The biomass pyramid can be inverted.
C) An energy pyramid can never be reversed.
D) The base of a pyramid is not always represented by the producer. E) A biomass pyramid represents the amount of organic matter found at each tropic level
C. is the wrong option. This is because it represented the energy fixed in each tropic level . it is never inverted because it flow upwards in the ecosystem.

Sternal angle marks the joint between the sternum and the 2nd rib.
Option E.
<h3><u>Explanation:</u></h3>
Sternum is the breast bone which is a dorsi ventrally flattened bone present in thorax of human. It gives the support for the ribs where the ribs join. A sternum has three parts - Manubrium sterni, body of sternum and the xyphoid process.
The sternum has attachments of a total of 10 ribs and clavicle. The clavicle and the first rib joins in the Manubrium sterni, and the 3rd to 10th rib joins in the body of sternum. The 2nd rib joins in a facet which is partly in Manubrium sterni and partly in body of sternum. This place id also called the sternal angle. So the sternal angle marks the joint of 2nd rib to sternum.
