Answer:
1.46 x [tex]10^{11}[/tex] krill in 365 days.
Explanation:
The adult killer whale eats 4.0 x [tex]10^{8}[/tex] (400 000 000) krill in a day.
Number of krill that the adult whale would eat in 3.65 x [tex]10^{2}[/tex] (365) days can be determined as;
= Number of krill eaten per day x number of days
= 4.0 x [tex]10^{8}[/tex] x 3.65 x [tex]10^{2}[/tex]
= 1.46 x [tex]10^{11}[/tex]
Therefore, an adult killer whale would eat 1.46 x [tex]10^{11}[/tex] krill in a year (365 days).
