26 de jun. de 2024 · 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. The second trophic level ( primary consumers) is occupied by zooplankton which feed off the phytoplankton. Higher order consumers complete the web.
2 de jul. de 2024 · Food webs can be divided into two main biological classifications: (i) macro-level food webs, which map interactions predominantly among the populations of multicellular organisms, with microorganisms typically depicted as ‘decomposers’ or sometimes producers [6], and (ii) microbial food webs, which detail the interplay of microorganisms within specific ecosystems or hosts [7].
16 de jun. de 2024 · Phytoplankton is the base of several aquatic food webs. In a balanced ecosystem, they provide food for a wide range of sea creatures. Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow.
2 de jul. de 2024 · Here, we propose a multilayered food web conceptual model that combines microbial food webs and macro-organism food webs, which opens the door to a better understanding of food web ecology, biodiversity interactions, and ecological processes.
Hace 2 días · The ocean is the body of salt water that covers approx. 70.8% of Earth. In English, the term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. The following names describe five different areas of the ocean: Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic.
13 de jun. de 2024 · These efforts are often challenging due to complex food web interactions that vary across habitat types, salinity gradients, and hydrodynamic features, and over time. There is a growing effort to understand relationships and feedbacks among food webs in the San Francisco Estuary and Pacific Ocean.
Hace 4 días · Acidification threatens Arctic food webs from the base up. Arctic food webs are considered simple, meaning there are few steps in the food chain from small organisms to larger predators. For example, pteropods are "a key prey item of a number of higher predators – larger plankton, fish, seabirds, whales".
