food webs ... and because in marine ecosystems, there are phytoplankton as well. These microorggansims are not apparant in terrestrial food chains
food chain
Trophic levels and food chains are connected in number of ways. Trophic levels show the energy transfer throughout the species in different food chains.
trophic levels.
Dolphins are near the top of the marine food chain
The three trophic levels in a food chain are producers (plants), primary consumers (herbivores that eat plants), and secondary consumers (carnivores that eat herbivores).
The trophic level is the level in the food chain that an animal occupies. The armadillo belongs to both the second and third trophic levels.
three
The different levels in a food chain are known as trophic levels. There are multiple levels, starting at the bottom with autotrophs, mostly plants that make their own food, and ending with apex predators, that are at the top and have no predators of their own.
Ocean circulation patterns play a crucial role in moving nutrients and plankton, which are the base of the marine food chain. These patterns can transport plankton to areas where they are needed by higher trophic levels, influencing the distribution and abundance of marine species. Disruptions in ocean circulation can impact the marine food chain by altering nutrient availability and the distribution of species.
Successive stages of nourishment as represented by the links of the food chain. According to a grossly simplified scheme the primary producers (ie, phytoplankton) constitute the first trophic level, herbivorous zooplankton the second trophic level, and carnivorous organisms the third trophic level.
energy pyramid or nutrient pyramid.
False. The number of trophic levels in a food chain is influenced by factors such as energy availability, efficiency of energy transfer, and ecosystem stability. While energy loss can limit the number of trophic levels, in some cases, ecosystems can support more than 7 trophic levels.
