Why is death by perdators more natural or right then death by starvation

Because it is common in the ecosystem to be a predator to someone and a prey to someone else. It is very difficult for animals to die of starvation because the food chain is designed so that the food sources never expire. Bears eat salmon, but salmons keep reproducing and then they feed on on something else, so a bear can't die of starvation because there will always be salmon.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
