In chapter 7-8,describe two huge crises in the life of karana. Describe what these to events were?

Basically Karana and Ramo are left behind. The canoes are already making their way towards the ship when Ramo appears on the shore clutching his spear. Despite Karana's cries, Chief Matasaip refuses to turn back for the young boy. The waves are too strong, and would destroy the canoes.

When Karana and Ramo return to the abandoned village, they find that wild dogs have already eaten much of the food that the tribe left behind. For dinner, they eat the remainder of the abalone stores, but the next day have to start gathering their own food. Karana gathers seeds and gull eggs, while Ramo spears some small fish.
