A team of ecologists observed feeding patterns of several populations in the desert. The energy pyramid shown above depicts the feeding patterns the ecologists observed. Which of the following best explains the difference in the amount of available energy in the trophic levels of the desert ecosystem?

There is more available energy in the birds of prey because they have greater muscle mass for storing energy than organisms in lower trophic levels have.

There is more energy available in the second trophic level because less energy is needed for hunting compared to the higher trophic levels.

There is less available energy in the fourth trophic level because of the loss of energy through metabolism in each of the lower trophic levels.

There is less energy available in the producers because their tissues are less dense than those at higher trophic levels.

The common brushtail possum is a marsupial native to Australia. This possum was later introduced to New Zealand where it had no natural predators and had an abundant food supply. Which of these likely occurred in New Zealand a few years after the introduction of this possum?

The possum population increased substantially

The possum became extinct

The possum population evolved into a different species

The possums developed shorter life spans

DDT and other pesticides used over 50 years ago are still affecting the environment today. Scientists have found these substances in recent glacier runoff. Glacier runoff occurs during the summer, when precipitation that has fallen on glaciers during the winter is released. Ice layers from existing glaciers have been analyzed. The results of this analysis show that the concentrations of DDT and other pesticides were highest about 10 years after the use of these substances was banned.
What is one claim that can be made based on the scientists findings?

DDT and other pesticides cause glacier runoff during the summer.

It takes scientists more than 50 years to analyze a glacier.

Precipitation helps to break down pesticides.

The decisions of one human generation may have an impact on future generations.

Constance made the table above during a field investigation on ocean life. Based on Constance’s table, which of the following is a valid conclusion?

The warm water and abundant sunlight in the neritic zone limits the plankton population.

Organisms in the benthic zone must be able to tolerate occasional air exposure.

There are no producers in the benthic zone that rely on photosynthesis.

Organisms in the intertidal zone must be able to withstand very cold water.

The tropical rain forests have been called the lungs of the planet. They take huge quantities of carbon dioxide from the atmosphere during photosynthesis and give off large quantities of oxygen. Vast tracts of tropical rain forests are being cleared for farms by people cutting down and burning the trees. Which of the following is the best hypothesis about the effect that rain forest destruction may have on atmospheric carbon dioxide levels?

Cutting down trees, which take carbon dioxide from the atmosphere, and burning the trees, which adds carbon dioxide to the atmosphere, will increase atmospheric carbon dioxide levels.

Cutting down rain forest trees will decrease atmospheric carbon dioxide levels, because plants give off carbon dioxide as a result of cellular respiration.

Rain forest destruction will not influence overall carbon dioxide levels, because it will affect only areas around the equator.

Any carbon dioxide added to the atmosphere because of rain forest destruction will fall into the oceans and be used in building coral reefs.

Your class has been observing the population growth of a species of Paramecium, a single-celled organism, for 18 days. Your data are shown in the graph above. Food was occasionally added to the test tube in which the paramecia were grown. There are limited resources so the population stays constant around the carrying capacity.
Look at the graph above. What is the carrying capacity of the test-tube environment as long as food is added?

About 100 paramecia

About 60 paramecia

About 10 paramecia

About 50 paramecia

Latecia conducted an experimental investigation of the gas production of a water plant. She placed a beaker upside down over a water plant submerged in water and collected the gas that the water plant produced when kept in sunlight. After several days, a large bubble of gas collected in the upside-down beaker.
Given that the gas came from the water plant, what are the contents of the bubble of gas collected in the test tube?

The gas contains one of the products of respiration, carbon dioxide.

The gas contains one of the products of respiration, oxygen.

The gas contains one of the products of photosynthesis, carbon dioxide.

The gas contains one of the products of photosynthesis, oxygen.
