which organism is the carnivore in this food web ? a. Krill, B. marine Phytoplankton, c. adelie penguin , d. zooplankton?
In the epipelagic zone, the food web typically includes phytoplankton at the base, which are then eaten by zooplankton. Zooplankton are consumed by small fish, which in turn are preyed upon by larger fish, marine mammals, and birds. This food chain provides energy and nutrients to sustain life in the epipelagic zone.
Zooplankton get their food from eating phytoplankton. The phytoplankton are the base of the food chain. Zooplankton are primary consumers or the second step in the food chain.
Zooplankton is an animal. Its included in the food chain.

Zooplankton are small animals that primary feed on phytoplankton, which are tiny plant-like organisms found in the water. They may also consume other zooplankton, organic particles, and detritus as food sources. This makes them an important link in the marine food web, providing energy to a wide variety of marine organisms.
Tetrahymena, a genus of ciliated protozoa, primarily feeds on bacteria and small organic particles, rather than zooplankton. It captures food using its cilia to create water currents that draw in particles. In contrast, zooplankton, which are larger organisms, often graze on phytoplankton and other microscopic life forms. Thus, Tetrahymena does not eat zooplankton; instead, it occupies a different niche in the aquatic food web.
Answer is primary consumer. (depending on the type of web you are constructing) krill is a primary consumer or secondary because the primarys include phytoplanktons, zooplankton algae etc and since kill eat phyto and zoo plankton it would be a primary consumer or in a food web it would be in the second bottom row making it secondary in the food piramid or web. eg. bottom row: phytoplankton and zooplankton second bottom row: krill, prawns, and fish then the next up are the tertiary and quaternary row, which are the higher levels in the food web.
Zooplankton primarily feed on phytoplankton (microscopic algae), bacteria, and other organic matter found in the water column. Some zooplankton species are herbivores, while others are carnivores that prey on smaller zooplankton or detritus. Grazing on phytoplankton is an essential part of the marine food web, as zooplankton serve as a crucial link between primary producers and higher trophic levels.

Small fish eat zooplankton along with many other things
