7. We use this example most of the time,

8. We use this example most of the time, however, phytoplankton,

9. We use this example most of the time, however, phytoplankton, and zooplankton are the basis for the aquatic transfer of energy.

10. The sun provides the energy for the phytoplankton. Zooplankton eat the phytoplankton.

11. The sun provides the energy for the phytoplankton. Zooplankton eat the phytoplankton. This energy then moves up the f ood chain

12. The sun provides the energy for the phytoplankton. Zooplankton eat the phytoplankton. This energy then moves up the food chain

13. Phytoplankton: Very small free floating aquatic plants that get energy from the sun.

14. Phytoplankton: Very small free floating aquatic plants that get energy from the sun. They produce oxygen for animals.

15. Phytoplankton: Very small free floating aquatic plants that get energy from the sun. They produce oxygen for animals. Photosynthesis

16. Phytoplankton: Very small free floating aquatic plants that get energy from the sun. They produce oxygen for animals. Photosynthesis The Sun provides energy for plants to g row, repair, and reproduce

28. Visit this website to research and answer this question. Why are phytoplankton important? https://www.whoi.edu/know-your-ocean/ocean-topics/ocean-life/phytoplankton/

29. Z ooplankton are an important element of the aquatic food chain. These organisms serve as an intermediary species in the food chain, transferring energy from planktonic algae (primary producers) to the larger invertebrate predators and fish who in turn feed on them.

30. Many are Protists

77. The aquatic food chain starts with the Sun. Energy from the sun is used by the phytoplankton. Phytoplankton get eaten by Zooplankton. The fish eat the zooplankton, and get eaten by larger fish. The seal eats the fish, and the Polar Bear eats the Seal.

78. A summary…

79. A summary… The ultimate source of energy (for most ecosystems) is the sun.

80. A summary… The ultimate source of energy (for most ecosystems) is the sun. The ultimate fate of energy in ecosystems is for it to be lost as heat.
