What is the food chain of the ocean?

A food chain in the ocean begins with tiny one-celled organisms called diatoms, which make their own food from sunlight. Shrimplike creatures eat the diatoms. Small fish eat the shrimplike creatures, and bigger fish eat the small fish.

What is an example of a marine food chain?

Chaetognaths and comb jellies eat the smaller larval fish, while larval crabs and small juvenile fish eat the chaetognaths. Large fish eat small fish. Dolphins, sharks and sea birds eat large fish. Baleen whales and whale sharks, although very large, eat zooplankton.

Which of the following organisms begins marine food chain?

Explanation: Marine food chain begins with phytoplankton. Phytoplankton is microscopic marine algae. Phytoplankton provides the foundation of the sea’s food chain in a balanced system. This phytoplankton captures the sun’s energy through photosynthesis.

Where does energy begin in a food chain?

producers
The food chain begins with producers, organisms such as green plants, that can make their own food. Through photosynthesis, producers convert solar energy to chemical energy, energy in the chemical bonds of the food.

What are 3 consumers in the ocean?

Primary consumers in the ocean include zooplankton, small fish, and crustaceans. The secondary consumers are fish, coral, penguins, whales, and other species that eat the zooplankton. The top predators in the ocean, sharks, killer whales, and leopard seals, eat both primary and secondary consumers.

What is food chain and example?

The definition of a food chain is a system where a small animal is the food for a larger animal which, in turn, is the food for an even larger animal. An example of food chain is a fly being eaten by a frog and then the frog is eaten by a larger animal.

Are humans at top of food chain?

It’s a platitude that we’ve all heard dozens of times, whether to justify our treatment of other species or simply to celebrate a carnivorous lifestyle: humans are the top of the food chain. Ecologists, though, have a statistical way of calculating a species’ trophic level—its level, or rank, in a food chain.

What organisms are at the top of the food chain?

species at the top of the food chain, with no predators of its own. Also called an alpha predator or apex predator. one of three positions on the food chain: autotrophs (first), herbivores (second), and carnivores and omnivores (third).

  Who is top of the food chain on Earth?

  At the top of the scale are meat-eaters that don’t have any predators themselves, such as polar bears and orca whales. Instead, we sit somewhere between pigs and anchovies, scientists reported recently. That puts us right in the middle of the chain, with polar bears and orca whales occupying the highest position.
