Unit 1 Quiz: The Living World: Ecosystems

What is a predator-prey relationship?

• A relationship where two species compete for limited resources

• A relationship where one organism eats another organism

• A relationship where two species mutually benefit from each other

• A relationship where two species live in close proximity without any interaction

What is symbiosis?

• A relationship where two species mutually benefit from each other

• A relationship where two species live in close proximity without any interaction

• A relationship where one organism eats another organism

• A relationship where two species compete for limited resources

What is resource partitioning?

• The process of two species mutually benefiting from each other

• The process of using resources in different ways, places, or at different times to reduce competition

• The process of one organism eating another organism

• The process of two species living in close proximity without any interaction

Which of the following is a terrestrial biome?

• Coral reef

• Tropical rainforest

• Marshland

• Estuary

What factors contribute to the global distribution of terrestrial biomes?

• Climate, geography, latitude and altitude, and water availability

• Salinity, depth, turbidity, nutrient availability, and temperature

• Climate, geography, latitude and altitude, nutrient availability, and soil

• Salinity, depth, turbidity, and temperature

Which of the following is a freshwater biome?

• Marshland

• Ocean

• Savanna

• Coral reef

What is the primary reservoir of water in the hydrologic cycle?

• Ice caps

• Groundwater

• Oceans

• Lakes

What is net primary productivity (NPP)?

• The total rate of photosynthesis in a given area

• The rate at which solar energy is converted into organic compounds via photosynthesis over a unit of time

• The rate at which energy flows from the sun to producers in the lowest trophic levels

• The rate of energy storage by photosynthesizers in a given area, after subtracting the energy lost to respiration

What is the 10% rule?

• Approximately 25% of energy is passed on from one trophic level to the next

• Approximately 50% of energy is passed on from one trophic level to the next

• Approximately 90% of energy is passed on from one trophic level to the next

• Approximately 10% of energy is passed on from one trophic level to the next

What is a food web?

• A linear representation of the flow of energy and nutrients from one organism to another

• A model of an interlocking pattern of food chains that depicts the flow of energy and nutrients in two or more food chains

• A relationship where two species compete for limited resources

• A relationship where two species mutually benefit from each other
