Aphids are small plant-eating insects that secrete sugary substances that attract ants. In exchange for receiving access to the aphids' sugary excretions, ants attack the predators and parasites of aphids. The relationship between ants and aphids is an example of what kind of symbiotic association? (Standards 6.1f, 6.1g, 6.3a)

Sample Question
Termites are small insects that eat wood causing so much damage that they can eventually cause a house to fall down. However, termites cannot make enzymes that digest cellulose, the main component in wood. A small protozoan called Trichonympha sphaerica lives inside the termite’s gut and excretes enzymes to break down cellulose. However, the protozoa itself cannot make the enzymes. Instead, a species of bacteria that lives inside the protozoa produces the enzyme. What type of relationships are described in this passage? (Standards 6.1f, 6.1g, 6.3a)

Sample Question
If the flow of energy in an Arctic ecosystem goes through a simple food chain from seaweeds to fish to seals to polar bears, then which of the following is TRUE?

The carnivores can provide more food for the Eskimos than the herbivores can.
