Answer
Since the whole ecosystem depends on the primary producers for survival, definitely all the sizes of the population in the ecosystem will be affected. The producers(green plants ) makes use of sunlight to supply the needed energy as food substances for the consumers ( rabbit) to feed on, and the Consumers is eaten by the top level consumers e.g Leopard.
Therefore, if the population of top level consumers is decreasing, this indicated that the secondary consumers population is reducing, due to reduction in energy obtained from primary producers which has dropped due to the decline in productivity.Hence nothing fort the top consumers to feed on.

Chemical properties are tested on not because of their color or their appearance but how they will react to certain tests. Such as; is it flammable? Could it be toxic? Physical properties are tested on and observed because of the texture, the color, smell and etc.
Hope this helps!

Answer:
c. Sarcomere
Explanation:
Sarcomere is one of the basic components of striated muscle that allows muscle contraction. That is, it is the contractile unit in the muscle cell.
The sarcomere is made up of a protein complex, the most important of which are actin and myosin. In the presence of Ca2 +, the ends of the myosin bind to nearby actin molecules and fold with great velocity. The actin filament then moves to the center of the sarcomere, triggering the approach of the two Z lines. This causes the sarcomere to shrink and, to a large extent, lead to contraction of the entire muscle.
