Which of the following organisms is likely to be in the lowest trophic level of an ocean food chain?
O Leopard Seal
O Penguin
O Krill
O Plankton
O Fish

Plankton

Explanation:

Plankton are small organisms that exist in water and are too weak to swim against the currents of the ocean and the seas. This leads to them going wherever the currents take them. Plankton can be either plants or animals.

Of the organisms listed, they are on the lowest trophic level and provide a source of food to other organisms of different sizes ranging from krill to whales.

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
