Predators at the top level of the trophic pyramid include animals like sharks and dolphins. However, not all top marine predators live in the sea. The albatross is an important predator at the top of the marine food web in Otago. Humans are also top-level consumers in the marine food web.
1 Φεβ 2019 · Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Primary consumers are in turn eaten by fish, small sharks, corals, and baleen whales.
19 Οκτ 2023 · On the ocean's surface waters, microscopic animals— zooplankton, which include jellyfish and the larval stages of some fish, barnacles, and mollusks—drift across the sea, grazing opportunistically. Larger herbivores include surgeonfish, parrotfish, green turtles, and manatees.
19 Οκτ 2023 · They eat grasses, shrubs, and trees. In a desert ecosystem, a mouse that eats seeds and fruits is a primary consumer. In an ocean ecosystem, many types of fish and turtles are herbivores that eat algae and seagrass. In kelp forests, seaweeds known as giant kelp provide shelter and food for an entire ecosystem.
Humans rely on the oceans for food, and thus play a role as apex predators, influencing aquatic food webs through overfishing. Human activities may decrease the biomass of fished animals, decrease biodiversity, and alter the species present in an ecosystem.
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.
12 Φεβ 2003 · Food web analysis and estimates of consumption are essential for understanding which ecosystems can support additional species, and which may be less stable and susceptible to species loss...
