John is completing an internship in biology at the clearwater marine aquarium. while interning there, he monitors an outdoor phy
toplankton exhibit to observe how populations of phytoplankton change when exposed to light. it is observed that each year the phytoplankton population within the exhibit increased by 3,000 organisms when it was exposed to high amounts of sunlight. a new high rise apartment complex that overlooks the beach is being built. the new apartment complex will stand between the marine aquarium and the sun. The Phytoplankton that were receiving 8-12 hours of sunlight each day will now have between 2-5 hours of sunlight. which of the following is most likely to occur as a result of the new apartment complex? A. The Population will decline over time
B. The Population will decrease there need for food
C. The Population will migrate to another body of water.
D. The population will choose to evolve new adaptations
<em>The correct option is A. The Population will decline over time</em>
Explanation:
As the phytoplanktons won't receive enough sunlight, they will not be able to make enough food by photosynthesis. As a result, the phytoplanktons will start to die and they won't be able to reproduce abundantly like before. Hence, the population will decline.
Other options like option B are false because the population will not decrease their need for food. They will start to die due to lack of food and sunlight.
The environment the moths lived in used to be unpolluted. This made dark moths rare. As the area where light moths were found became more polluted, the light moths became less common in the polluted/dark areas. Light Moths began to evolve after not being able to survive in dark forests, they began to get darker and blend in with the polluted area to be safe from predators.
