Detailed explanation-1: -Antarctic krill form one of the largest biomasses of any individual animal species.

Detailed explanation-2: -Antarctic krill (Euphausia superba, hereafter referred as krill) is a key dietary item for vertebrate predators, such as whales, seals, seabirds, and fish, as well as for invertebrates1. At between 300 and 500 million tonnes2 its biomass is the largest of any multicellular wild animal species on the planet3.

Detailed explanation-3: -Answer and Explanation: The trophic level that contains the greatest biomass in most ecosystems is the producers. Producers are organisms that are able to make their own food from sunlight or chemicals. Thus, they have access to 100% of the energy available.

Detailed explanation-4: -The domain that represents the highest biomass on earth is bacteria. In a terrestrial food chain, the biomass of an organism decreases as you move to high trophic levels. Biomass can be described as the total dry weight of an organism at a given trophic level.

Detailed explanation-5: -Krill are small, shrimp-like crustaceans that are an important food source for many animals, including baleen whales. They are the building blocks of the marine food web. They are the most commonly eaten crustacean among marine animals.
