Firstly, food chains are considered to be oversimplified and have been replaced with food webs as a more accurate representation of the energy relationships in an ecosystem. Having said that, let's use a food chain as simplified elements of a food web. The coastal food chain that you have used as an example is not quite accurate as these organisms do not necessarily eat one another. Let me offer this for a coastal food chain:

phytoplankton-->zooplankton-->fish fry-->larger fish.

For an open ocean food chain how about:

phytoplankton-->zooplankton-->jellyfish-->sea turtle.
