Answer:
The whale is heterotrophic.
Explanation:
Energy is needed by organisms to perform their life functions. Organisms, in nature, feed on one another for energy source. Some organisms are, however, capable of synthesizing their own food or energy source via a process called photosynthesis. This is the case of the phytoplankton in the question. These organisms are, therefore, called AUTOTROPHIC ORGANISMS or PRODUCERS.
On the other hand, some organisms are incapable of this self-production of energy source. Hence, they rely on other organisms for it. These category of organisms are called HETEROTROPHIC organisms, which is the category the large whale fall into due to its dependence on phytoplankton for energy source.
A at right angles
•
The movement produces oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of light energy called a photon. ... Magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave.
