Marine life can be roughly grouped into autotrophs and heterotrophs according to their roles within the food web: the former include photosynthetic and the much rarer chemosynthetic organisms (chemoautotrophs) that can convert inorganic molecules into organic compounds using energy from sunlight or exothermic oxidation, such as cyanobacteria ...
General characteristics of a large marine ecosystem (Gulf of Alaska). Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal ...
A lion (Panthera leo).Lions are an example of charismatic megafauna, a group of wildlife species that are especially popular in human culture.. Wildlife refers to undomesticated animals and uncultivated plant species which can exist in their natural habitat, but has come to include all organisms that grow or live wild in an area without being introduced by humans.

Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many phyla , families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy .
Seashore wildlife habitats exist from the Tropics to the Arctic and Antarctic. Seashores and beaches provide varied habitats in different parts of the world, and even within the same beach . Phytoplankton is at the bottom of some food chains , while zooplankton and other organisms eat phytoplankton.
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [58]

Culling is the deliberate and selective killing of wildlife by governments for various purposes. An example of this is shark culling, in which "shark control" programs in Queensland and New South Wales (in Australia) have killed thousands of sharks, as well as turtles, dolphins, whales, and other marine life.
