Physical weathering, also known as disaggregation or mechanical weathering, refers to the category of procedures, which makes the disintegration of rocks in the absence of chemical modification. In general, the mechanical weathering takes place due to the build-up of pressure within the rocks.
However, the rocks can also get worn away by a procedure known as abrasion. Abrasion refers to the disintegration of rocks due to friction.
Answer: No
Explanation: The number tertiary consumers will be less than the number of secondary consumers because as we move up in the ecological pyramid, the energy decreases.

They transfer only 10 per cent of the total energy they have. The primary consumers transfer only 10 per cent of the total energy they have to consumers.
The number of organism decreases along with increase in the tropic level of energy pyramid.
