Review 9: SC.7.L.17.2 - SC.8.L.18.4

(SC.7.L.17.2) Organisms interact with organisms of different species. They also interact with individuals of the same species. Which type of interaction is most likely to occur between two organisms of the same species?

• parasitism
• predation
• competition
• commensalism

(SC.7.L.17.2) The picture below shows organisms that have relationships with trees. For example, shelf fungus receive water and nutrients from the tree, causing the tree to rot and eventually die over time. What relationship exists between the shelf fungus and the tree?

• commensalism
• mutualism
• parasitism
• competition

(SC.7.L.17.2) Two types of relationships organisms can have are called mutualism and commensalism. Which of the following best compares these two types of relationships?

• In mutualism, one organism is harmed; whereas in commensalism, two organisms are harmed.
• In mutualism, two organisms benefit; whereas in commensalism, one organism benefits.
• In mutualism, two organisms are harmed; whereas in commensalism, one organism benefits.
• In mutualism, one organism benefits; whereas in commensalism, two organisms benefit.

(SC.7.L.17.2) One type of interaction that can occur between organisms is a predator/prey relationship. How would a prey species most likely be affected if disease killed most of the predator species?

• The prey population would increase.
• The prey population would no longer be able to live in the ecosystem.
• The prey population would need to find other food.
• The prey population would start hunting the predators.

(SC.7.L.17.2) In the United States, there has been a great decline in the size of honeybee populations. Scientists are very concerned that this will cause a decrease in the populations of flowering plants. Using this information, what type of relationship do honeybees and flowering plants have?

• competition; the honeybees and the plants compete for resources
• mutualism; the honeybees and plants both benefit from the relationship
• parasitic; honeybees are parasites of plants
• commensalism; the honeybees benefit but the plants are not affected

(SC.7.L.17.2) An introduced species is one that is accidentally or intentionally added to an ecosystem. Lionfish are an introduced species originally from the Western Pacific Ocean that has the potential to harm Florida’s coral reefs. Lionfish reproduce all year long and consume parrotfish, a beneficial species of fish that eats algae. Over time, this may cause the reefs to be overgrown with algae. Which of the following best describes the relationship between parrotfish and lionfish?

• commensalism
• predation
• competition
• mutualism

(SC.7.L.17.2) Students in Ms. Greene’s class observed the organisms in an ecosystem near the school. They made this table classifying some of the relationships between organisms in the ecosystem, but they forgot to add a label to each column of the table. What column heads should be added to the table?

• A: Two Organisms Benefit, B: One Organism Benefits
• A: One Organism Benefits, B: Two Organisms Benefit
• A: One Organism Benefits, B: One Organism Harmed
• A: Two Organisms Benefit, B: Two Organisms Harmed

• small fish and phytoplankton

(SC.7.L.17.2) Honeybees eat nectar found in flowers. In the process of gathering nectar, bees carry pollen from flower to flower. This allows the flowering plants to reproduce. Based on this information, what is the best classification for the relationship between honeybees and flowering plants?

• competition
• commensalism
• parasitism
• mutualism

(SC.7.L.17.2) The graph below shows how the numbers of two different organisms in a forest changed over time. The changes in population sizes can be used to make inferences about the relationship between wolves and rabbits in this forest. Based on the information in the graph, what is the most likely relationship between these organisms?

• Rabbits and wolves rely on the same food source.
• Wolves and rabbits have a mutualistic relationship.
• Wolves are predators of rabbits.
• The relationship between wolves and rabbits is commensalism.
