Question

John relies on the information from a local fisheries research institute. They used an automatic plankton sampling systems that screens 14 liters of water daily. Below are the results that indicate the amount of plankton in the water and the sardine sizes.

Answer 1

Water Samples Plankton Population Average Sardine Size
February 14,352/ liter 5 in
March 16,321/ liter 7 in

West Coast

Water Samples Plankton Population Average Sardine Size
February 12,231/liter 4 in
March 13,781/liter 5 in

Which statement best analyzes the data?

An increase in plankton population results in a decrease in sardine size.

A decrease in plankton population results in an increase in sardine size.

An increase in plankton population results in an increase in sardine size.

An increase in the amount of plankton per liter results in a decrease in sardine size

Answer 2

B.

Answer 3

We have discovered dead fish floating around our boat. We think that the dead fish are caused by a sudden increase in a red tide algae bloom. What would be a properly written hypothesis for our belief?

If fish are floating, then they are dead.

If the red tide alga blooms quickly, then a high number of fish will die.

If fish die, then it is because of the algae.

If fish are dead, then a sudden increase in red tide will occur.

Answer 7

Phytoplankton Productivity/Temperature of Water at Sea Surface
The graph shows phytoplankton growth in relation to the temperature of the water at the surface level. For species one, 80 degrees F had a growth rate of 5.5, 85 degrees F had a growth rate of 4.5, 90 degrees F had a growth rate of 3.2, 95 degrees F had a growth rate of 3.1, and 100 degrees F had a growth rate of 3.0. For species two, 80 degrees F had a growth rate of 4.2, 85 degrees F had a growth rate of 4.1, 90 degrees F had a growth rate of 4.0, 95 degrees F had a growth rate of 3.7, and 100 degrees F had a growth rate of 3.2. For species three, 80 degrees F had a growth rate of 4.9, 85 degrees F had a growth rate of 4.9, 90 degrees F had a growth rate of 4.7, 95 degrees F had a growth rate of 4.3, and 100 degrees F had a growth rate of 3.8.
According to the table, which is true?


Warmer surface temperatures results in increased phytoplankton productivity.

Warmer surface temperatures have no effect on phytoplankton productivity.

Cooler surface temperatures result in increased phytoplankton productivity.

Cooler surface temperatures have no effect on phytoplankton productivity.
