What do you think these herbivores feed on?
The correct order of the African species is
8
Animals such as cheetahs generally have no predators feeding on them. They are at the top of the food chain. Why
do you think this is?
9
Like the cheetah, humans are at the top of the food chain. However, depending on what you eat, you can be a
primary, secondary, or even tertiary consumer. At what trophic level are you when you eat: (a) a beef hotdog?
(b) trout?

energy, what is one way to make sure that the planet
can support more people?

Circle: TRUE OR FALSE? Aquatic biomes make up a large part of earth’s surface veering more area than all terrestrial
biomes added together.

Working left to rigt click on the arrow up for increase and arrow down for decrease. Be sure to write your hypothesis
below first before clicking on the “Global experiment” button. You do not need to type your hypothesis on the
computer because you have written it here. Just place a letter in the box and then click on the “Global experiment”
button for the answer.
1. MARINE PRODUCERS INCREASE - Experiments have shown that fertilizing the ocean with additional iron would
greatly enhance photosynthesis and the ocean's CO2 uptake. How do you think large-scale fertilization of the ocean
with iron would affect global temperatures?
a. YOUR HYPOTHESIS:
b. ANSWER:
2. MARINE PRODUCERS DECREASE - Pollution of the ocean with toxic chemicals and disruption of the ocean floor in
shallow water significantly reduces the number of photosynthetic organisms. Since 80% of the Earth is covered with
ocean, most photosynthesis is done by marine autotrophs. How do you think pollution of the ocean would affect
global temperatures?
a. YOUR HYPOTHESIS:
b. ANSWER:
3. TERRESTRIAL PRODUCERS INCREASE - Old-growth tropical and temperate forests are responsible for removing large
concentrations of CO2 from the atmosphere. In tropical rain forests, photosynthesis occurs every day of the year.
Temperate forests remove a great deal of CO2 during their summer growing season. How do you think increasing the
global expanse of the tropical and temperate forests would affect global temperature?
a. YOUR HYPOTHESIS:
b. ANSWER:
4. TERRESTRIAL PRODUCERS DECREASE - Many scientists believe that tropical rain forests are being replaced with tilled
fields and pastures at an alarming rate. These forests are capable of removing vast amounts of the CO2 from the
atmosphere. How do you think a continuing reduction in tropical and temperate forests would affect global
temperatures?
a. YOUR HYPOTHESIS:
b. ANSWER:
5. CONSUMERS INCREASE - For eons of time, the amount of CO2 photosynthetic organisms removed from the
atmosphere was balanced by the amount of CO2 consumers returned to the atmosphere through respiration. How
do you think a large increase in the population of consumers would affect global temperatures?
a. YOUR HYPOTHESIS:
b. ANSWER:
6. CONSUMERS DECREASE - Because respiration requires large amounts of oxygen, most heterotrophs are absolutely
dependent on oxygen for life. If the amount of oxygen in the atmosphere was greatly reduced, many organisms
would die and no longer consume reduced carbon or produce CO2. How do you think a large decrease in consumers
would affect global temperatures?
a. YOUR HYPOTHESIS:
b. ANSWER:
7. INDUSTRY INCREASE - Since the industrial revolution, humans have been burning coal, natural gas, and oil to provide
the energy required to power industrial machines. When these fossil fuels are burned, CO2 is produced and released
into the atmosphere. As the planet becomes increasingly industrialized, CO2 production from the burning of fossil
fuels is likely to increase. How do you think increasing industrial CO2 production would affect global temperatures?
a. YOUR HYPOTHESIS:
b. ANSWER:
8. INDUSTRY DECREASE - Solar, nuclear, and geothermal energy sources provide energy without producing large
amounts of CO2. If humans increasingly switch to these alternate sources of energy, they would significantly reduce
the amount of industrially-produced CO2. How do you think a reduction in industrial CO2 production would affect
global temperatures?
a. YOUR HYPOTHESIS:
b. ANSWER:
