The Eurasian wigeon is a bird of open wetlands, such as wet grassland or marshes with some taller vegetation, and usually feeds by dabbling for plant food or grazing, which it does very readily. It nests on the ground, near water and under cover. It is highly gregarious outside of the breeding season and will form large flocks.
An American wigeon × mallard hybrid has also been recorded. [5] The American wigeon was formerly called the baldpate by ornithologists, and some people still use that name, especially hunters. The diet of the wigeon consists mainly of grass leaves (~80%), other food types eaten are seeds (~10%) and roots and stems (~5%). [6]

The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
Marine mammal adaptation to an aquatic lifestyle varies considerably between species. Both cetaceans and sirenians are fully aquatic and therefore are obligate water dwellers. Pinnipeds are semiaquatic; they spend the majority of their time in the water but need to return to land for important activities such as mating, breeding and molting.
The tiny (0.6 μm) marine cyanobacterium Prochlorococcus, discovered in 1986, forms today an important part of the base of the ocean food chain and accounts for much of the photosynthesis of the open ocean [140] and an estimated 20% of the oxygen in the Earth's atmosphere. [141]
The gadwall is a bird of open wetlands, such as prairie or steppe lakes, wet grassland or marshes with dense fringing vegetation, and usually feeds by dabbling for plant food with head submerged. They can also dive underwater for food, more proficiently than other dabbling ducks, and may also steal food from diving birds such as coots. [ 15 ]

They mainly eat vegetation or insects near to the water, consuming animals such as larvae, crustaceans, and mollusks. They likewise eat plant foods: leaves as well as seeds, grains, and nuts.
