Cyclops bicuspidatus is a planktonic species of copepod found throughout the world, except Australia, [4] and characteristic of the Great Lakes of North America. [5] It is a deep water species found throughout the year with peak abundance occurring in May or June. [5]
In mathematics, for a function :, the image of an input value is the single output value produced by when passed . The preimage of an output value y {\displaystyle y} is the set of input values that produce y {\displaystyle y} .
A planktivore is an aquatic organism that feeds on planktonic food, including zooplankton and phytoplankton. [1] [2] Planktivorous organisms encompass a range of some of the planet's smallest to largest multicellular animals in both the present day and in the past billion years; basking sharks and copepods are just two examples of giant and microscopic organisms that feed upon plankton.
The global biomass of gelatinous zooplankton (sometimes referred to as jelly‐C) within the upper 200 m of the ocean amounts to 0.038 Pg C. [21] Calculations for mesozooplankton (200 μm to 2 cm) suggest about 0.20 Pg C. [22] The short life span of most gelatinous zooplankton, from weeks up to 2 to 12 months, [23] [24] suggests biomass ...

[140] [141] [142] The export rate of the lipid pump may vary from 1–9.3 g C m −2 y −1 across temperate and subpolar regions containing seasonally-migrating zooplankton. [142] The role of zooplankton, and particularly copepods, in the food web is crucial to the survival of higher trophic level organisms whose primary source of nutrition is ...
Micronekton typically ranges in size from 2 to 20 cm, macro-zooplankton from 2 mm to 2 cm, meso-zooplankton from 0.2 to 2 mm and micro-zooplankton from 20 μm to 0.2 mm. Micronekton represents 3.8-11.8 billion tons of mesopelagic fishes worldwide, [3] [4] approximately 380 million tons of Antarctic krill in the Southern Ocean [5] and a global ...
Fish larvae are part of the zooplankton that eat smaller plankton, while fish eggs carry their own food supply. Both eggs and larvae are themselves eaten by larger animals. [2] [3] Fish can produce high numbers of eggs which are often released into the open water column. Fish eggs typically have a diameter of about 1 millimetre (0.039 in).
