17. Five species of salmon live in Alaska and migrate at different times of the summer into streams to spawn. A food chain composed of many marine organisms that culminates in salmon now is extended to land via grizzlies, bald eagles and an assortment of gulls …. It is all part of the circle of life

Bald Eagles
Grizzlies
Gulls
Scav.

21. Spawning Some species migrate to spawn
Some species of fish are “broadcast spawners”
Others have extensive courtship displays as in the cod and its close relative, the haddock
Fertilization may be internal (sharks and a few bony fish) or external
Number of eggs produced in a spawn is directly correlated to extent of parental care
