Which characteristic is found in the whale but not in the phytoplankton?
Rare images of blue whale feeding behavior
Killer whales (orca) are massive marine apex predators that eat a range of large prey. However, the majority of biological activity in the ocean occurs among microscopic marine organisms, such as marine bacteria and phytoplankton, which cannot be seen individually with the naked eye. 1st
The plants, animals, and other species that live in the salt water of the sea or ocean, or the brackish water of coastal estuaries, are known as marine life. Sea life has an effect on the planet’s natural ecosystem on a fundamental basis. Microorganisms, which make up the majority of marine organisms, generate oxygen and sequester carbon. Marine life shapes and protects shorelines, and certain marine species also assist in the formation of new land. The word “marine” comes from the Latin word “mare,” which means “water” or “ocean.”
The majority of life forms began their evolution in aquatic environments. Oceans cover about 90% of the planet’s surface area and have 90% of the world’s living space.  The first vertebrates emerged in the form of fish, which are only found in water. Some of these developed into amphibians, creatures that spend part of their lives in the water and part on land. Some fish developed into land animals, such as seals, dolphins, and whales, and then returned to the sea as seals, dolphins, or whales. Kelp and algae are aquatic plant types that provide the foundation for certain underwater ecosystems. Plankton, especially phytoplankton, which are key primary producers, is the general foundation of the ocean food chain.

The SOCCOM program data portal (https://soccom.princeton.edu/content/data-access) has BGC-Argo float data. The data set used in this analysis corresponds to the low-resolution data snapshot released as a MATLAB data file40 on March 12th, 2019. NASA’s OceanColor Web (https://oceancolor.gsfc.nasa.gov) has remote sensing PAR info. The GEOTRACES International Data Assembly Centre (https://www.bodc.ac.uk/geotraces/data/) has dissolved iron data.
http://sites.science.oregonstate.edu/ocean.productivity/cbpm2.code.php contains the phytoplankton growth model (CbPM) code. The science programming software MATLAB Version: 220.127.116.118062 was used for all tests (R2017a).

The whale shark (Rhincodon typus) is the world’s largest known extant fish species. It is a slow-moving, filter-feeding carpet shark. The longest confirmed person measured 18.8 meters (62 feet). [eight] The whale shark holds several world records for size, including being the world’s largest living nonmammalian vertebrate. It is the only extant member of the Rhincodon genus and the Rhincodontidae family, which belongs to the subclass Elasmobranchii of the class Chondrichthyes. It was previously known as Rhiniodon in the Rhinodontidae family.
The whale shark can be found in open waters of tropical oceans and is rarely found in water below 21 degrees Celsius (70 degrees Fahrenheit).
[two] Whale shark lifespans have been estimated to be 80–130 years based on observations of vertebral growth bands and free-swimming shark growth rates. [nine] [nine] [nine] Whale sharks have enormous mouths and filter feed, a feeding mode shared by only two other sharks: the megamouth shark and the basking shark. They eat plankton and small fish almost entirely and pose no danger to humans.

Plankton is the foundation of both marine and freshwater ecosystems, providing food for larger animals and, indirectly, humans whose fisheries depend on it. Plankton has only recently begun to be produced and used as a human resource, despite its high biological productivity and widespread distribution. Large-scale algae cultures have been shown to be theoretically feasible on many occasions. In this case, the unicellular green alga Chlorella has been used extensively. Output is geared toward a protein content of more than 50% thanks to ideal culture conditions. Although this protein has a good balance of essential amino acids, it is difficult to use because of its poor digestibility. As a source of food and gas exchange, phytoplankton may become increasingly important in space travel. The algae would convert the carbon dioxide emitted during spacecraft crew respiration into organic compounds, while the oxygen liberated during this process would help human respiration.
