Answer:
A. The whale is heterotrophic.
Explanation:
The whale is an aquatic animal that is heterotrophic in nature. Heterotrophic means that this animal lacks the ability to manufacture its own food because it depends on plants and animals as a source of food energy. Since the Whale is dependent on phytoplankton for food, this means that it is not a producer of food and as such is heterotrophic.
Phytoplankton is a marine alga. Algaes are prokaryotes and this means that they are unicellular animals without a membrane-bound nucleus. The Cell wall is mostly a characteristic of plants. So the first option is a perfect description of the whale and not its food source which is the phytoplankton.
<span>Scientific research has an integral relationship to environmental resources. Resources that exist in the environment can help scientific research by making available the material that is necessary to conduct experiments. Water is an environmental resource and scientists can test the water in the environment in order to see if there are toxic levels of chemicals in the water. Without these resources, the science would not be as relevant.</span>
