Answer 1

The true statement about a penguin's energy source is:

A penguin relies indirectly on the sun as an energy source.

Penguins eat fish and krill, which are part of the marine food chain that ultimately depends on phytoplankton, which perform photosynthesis and require sunlight for energy. Therefore, penguins obtain their energy indirectly from the sun through the food they consume. The other options are incorrect; penguins do not perform photosynthesis themselves, and while nutrients are important, the ultimate energy source is linked to the sun.
