Ecological Relationships and Interactions

In an ecological relationship, what is the term for an organism that hunts and kills other organisms for food?

• Prey

• Consumer

• Producer

• Predator

What happens to the antlion population when the ant population in a confined area increases?

• The antlion population decreases due to lack of food.

• The antlion population remains stable, unaffected by the ant population.

• The antlion population increases due to more available food.

• The antlion population migrates to find new food sources.

Which of the following is an example of competition for a biotic (LIVING) factor?

• Two plants competing for sunlight.

• Two antlions competing for ants.

• A plant growing in nutrient-poor soil.

• Animals seeking shelter from a storm.

What type of ecological relationship is characterized by one organism benefiting while the other is harmed?

• Mutualism

• Commensalism

• Parasitism

• Competition

How do Acacia ants benefit the Acacia tree in their mutualistic relationship?

• They provide the tree with extra nutrients.

• They help the tree absorb more sunlight.

• They protect the tree from consumers and eliminate competing plants.

• They pollinate the tree's flowers.

What defines a commensalistic relationship between two organisms?

• Both organisms benefit from the interaction.

• One organism benefits, and the other is harmed.

• One organism benefits, and the other is neither helped nor harmed.

• Both organisms are harmed by the interaction.

Why are ecological relationships important to study?

• They help predict weather patterns.

• They explain the geological history of Earth.

• They show how interactions impact populations and ecosystems.

• They are only relevant to microscopic organisms.
