In the Orangutan Energy Model you used, what happened to the energy levels of the majority of orangutans when the % of fruit trees decreased?

• energy was lowered because there was less food

• energy stayed the same because the orangutans didn't move around as much

• energy levels were greater because they didn't move around as much

What is the dependent variable in the simulation we started yesterday?

• the size of the rainforest space

• the number of orangutans

• the percent of fruit trees

• the energy level after 5 years

Why do people cut down tropical rainforests when they know it is harmful to the animals that live there?

• Cutting down tropical rainforests to sell or grow resources may be the only way for people in these areas to support themselves.

• People cut down tropical rainforests because they don’t realize there are animals living there.

• Cutting down tropical rainforests improves the environment by making more space for animals to live.

• People cut down rainforests to increase the number of orangutans.

What would be the criteria for a better design of an oil palm farm?

• A better-designed palm farm will ignore the needs of the farmers and focus only on protecting the animals.

• A better-designed palm farm will only make sure that farmers can still support themselves and their families.

• A better-designed palm farm needs to support living things in the tropical rainforest and farmers, too.

• A better-designed palm farm should only increase the number of fruit trees.

Which aspect of the picture represents a population of orangutans?

• the red dot represents an individual orangutan

• all of the dots (grey and red) represent a population of orangutans

• the grey dots represent a population of orangutans

• the red dot represents a population of orangutans

If we want a solution, we will have to make sure that

• farmers and rainforest animals have their needs met

• rainforest animals are protected at all costs

• farmers needs are met before worrying about rainforest ecosystems
