Frogs and toads undergo complete metamorphosis to change from water-dependent tadpoles to Sand-bound adults. Scientists working with two species of toads (A and B) notice that Species A takes 9 days from egg to adulthood, while Species B takes about 3 weeks to complete the process.
a. Josh claims that Species A most likely lives in the desert, where water supply is scarce, and it would be an advantage to get to adulthood quickly. Is he
correct? Explain your answer.
b. Scientists do a "water drop" experiment on Species B, where they place Species in a full tank of water for a week, then drain 75% of the water to
simulate pond-drying. After the water drop, it took Species B twelve days to reach adulthood from a fertilized egg. Describe why the ability to change
metamorphosis speed is an advantage for Species B.

the cell is the smallest structural and functional unit of living organisms, which can exist on its own. therefore, it is sometimes called the building block of life. some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.

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.
