In a food chain 90% of the energy is lost in the transfer at each trophic level, and only 10% passes as usable biological energy. what will happen if secondary consumers are removed from a food chain? a) energy transfer in the food chain would be completely stopped. b) energy transferred to the tertiary consumers would be increased by 40%. c) energy transfer to the subsequent trophic levels of the food chain will be disturbed. d) producers will transfer more energy to the subsequent trophic levels of the food chain.

The answer it's C)Energy transfer to the subsequent trophic levels of the food chain will be disturbed. 

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.

Ithink that its like 15 mph.
