From the outside, a whale's flippers appear to be flat, solid objects. However, when scientists observed the
bones within whale flippers they found bones like the
ones shown in the diagram.
Observing the bones made scientists ask more
questions about whale flippers. Scientists then used
the theory of evolution to understand how whales are
related to land mammals. They surmised that over
millions of years, the land mammals slowly adapted to
living near the sea and then living in the sea, where
solid flippers are more useful than fingers.
What part of the scientific cycle was used to
understand why whales have finger bones?

air enters through the nose, moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi andbronchioles till the alveoli.

answer;

a. sheep consumption efficiency would be reduced.

explanation;

-trophic efficiency is a measure of how much energy occurs at one level divided by the energy at the level immediately below it . trophic efficiency incorporates three types of efficiency:

-the proportion of available energy that is consumed (consumption efficiency).   it is the proportion of the available biomass that is ingested by consumers.

-the proportion of ingested food that is assimilated (assimilation efficiency).

-the proportion of assimilated food that goes into new consumer biomass (production efficiency).

-in this case, the grasshoppers would affect sheep by reducing the proportion of the available biomass that is ingested by the sheep.
