In an ecosystem, marsh snails feed on phytoplankton and painted turtles feed on marsh snails. Pollution has resulted in the depl
etion of phytoplankton. What effect would this situation likely have on the populations of marsh snails and painted turtles?
OA
The population of marsh snails will decrease, but the population of painted turtles will increase.
B. The population of marsh snails will increase, but the population of painted turtles will decrease.
OC The populations of marsh snails and painted turtles will increase.
D. The populations of marsh snails and painted turtles will decrease.
E. The populations of marsh snails and painted turtles will not be affected.
This is because since there are not enough phytoplankton to feed all the marsh snails. So they will decrease. When there is less marsh snails, the painted turtles will decrease because there will not be enough food. Therefore, both species are dependent on the phytoplankton.
Answer: Yes they are affected. By targeting the centrosome, some viruses hijack its functions, leading eventually either to cell death or to cell transformation.
