A local citizen science group is monitoring the water quality of a nearby lake. They gather water samples once a week on Wednesday between the hours of 7 A.M. and 9 A.M. from the same location. One day in August they were unable to sample within that time frame and collected the sample at 3 P.M. How might this difference in sample collection time affect the results?
Water sampled later in the day may be warmer and therefore have lower dissolved oxygen levels.
Water sampled later in the day may have increased insect respiration and therefore higher dissolved oxygen levels.
There would be no difference

A marsh food chain is shown. Grass → Grasshopper → Toad → Snake → Hawk. According to the food chain, how would an increase in the toad population MOST likely affect the other populations?
The grass population would decrease.
The hawk population would decrease.
The snake population would decrease.
The grasshopper population would decrease.
Why are producers always the first organisms in the food chain?
They prey on all other organisms.
They receive energy directly from the Sun.

They break down dead organisms and return nutrients to the environment.
The water pressure at 6000 m is more than 5850 pounds per square inch. Some researchers concluded that there was less biodiversity at this depth than at 50 m due to this extreme pressure. Other researchers concluded that the lesser biodiversity at 6000 m was due to a lack of food. Which statement explains why each group’s conclusion is acceptable?
Both light and pressure are dependent upon the movement of ocean currents.
Both research groups followed the scientific method in their investigations.
Both light and pressure affect what organisms will be found at different depths.
Both research groups compared the pressure and available light at different depths.
Photosynthetic organisms have many adaptive mechanisms that cause them to remain near the surface, such as buoyancy bubbles, droplets of oil, and increased surface area. Which statement explains the function of these mechanisms?
They stabilize pressure as the organisms move vertically through the different zones.
They help to keep the organisms in the layer with the greatest amount of light.
They are beneficial in camouflaging the phytoplankton from consumers.
They help absorb more wavelengths of light to maximize photosynthesis.
Yvette was looking at a map that showed where hurricanes had formed. She noticed that more hurricanes formed over tropical oceans than over colder ocean areas. Which of these BEST explains why more hurricanes form over tropical oceans than cold oceans?
