Question

Ryan lives in a house near a small lake. In the past few months, he has

noticed that there has been very little rainfall due to a drought. He
monitored the water depth in the lake by inserting a metal cylinder in the
sand and marking the water level each week for 4 weeks. He recorded his
data in the table below. What would MOST LIKELY take place in the lake
ecosystem based on this data?"
O
The fish population would decrease due to competition for food and shelter
O
The deer population would increase due to incropsed space for habitats
O
Trees near the water's edge will grow twice as fast during the drought
O
Fish-eating birds would find it more difficult to catch their prey in the lake

Answer 1

A. The fish population would decrease due to competition for food and shelter

Step-by-step explanation:

As the water depth of the lake decreases, the microorganisms that the fish usually eat will also be decreased be cramped into a smaller area. When this happen, competition among fishes to obtain their food will become fiercer.

Not only that, the reduction in lake depth also make the amount of area that small fishes can use to hide becomes smaller. This made them an easier target for bigger fishes, Both of these situation contributed to the decreasing fish population.
