The image shows a food web in an arctic ecosystem. rising temperatures in the arctic ocean can lead to large die-offs of phytoplankton, which are autotrophs. what would most likely happen in an arctic ecosystem if the phytoplankton population decreased? a)the populations of all other organisms in the food web would decrease because there would be less energy available in the ecosystem. b)the populations of krill and zooplankton would decrease, but no other organisms would be affected. c)the populations of all other organisms in the food web would increase because there would be more energy available in the ecosystem. d)the populations of zooplankton and krill would increase, but no other organisms would be affected.

 A)the populations of all other organisms in the food web would decrease because there would be less energy available in the ecosystem.

A food chain is a linear sequence of transfer of food and energy when one organism is consumed by other organisms. A food web is an interconnection of different food chains. One organism is dependent upon other organism for it's food requirement. In the given situation, the decline in the phytoplankton population will initially cause decline in the population of krill and zooplanktons but finally may also affect the population of other organisms which feed upon krill and zooplanktons. Therefore, the energy distribution in the food web will also be affected.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
