Which of the following trophic levels represents a primary producer in an aquatic food chain? A. Phytoplankton B. Herbivorous zooplankton C. Carnivorous zooplankton D. Baleen whale

A. Phytoplankton

Energy is transferred along food chains from one stage to the next. Which statement best explains how the energy is transferred? A. If a primary consumer stores 100kcal of energy, then a secondary consumer that feeds on the primary consumer will also have 100kcal of energy available. B. If a primary producer stores 10,000kcal of energy, then a tertiary consumer will have 10kcal of energy available. C. If a primary producer stores 100,000kcal of energy, then a secondary consumer will have 10,000kcal of energy available. D. If a secondary consumer stores 500kcal of energy, then a tertiary consumer that feeds on the secondary consumer will have 5,000kcal of energy available.

B. If a primary producer stores 10,000kcal of energy, then a tertiary consumer will have 10kcal of energy available.

Brittlebush, grasshopper, grasshopper mouse, rattlesnake, red-tailed hawk D. Brittlebush, red-tailed hawk, rattlesnake, grasshopper mouse, grasshopper

C. Brittlebush, grasshopper mouse, rattlesnakes, red-tailed hawk

The energy available to consumers determined by subtracting the energy used by plants from the total energy transformed by the process of photosynthesis. A. Primary productivity B. Gross primary productivity C. Net primary productivity D. Cellular respiration

C. Net primary productivity

This rate of reaction can be measured in the dark by determining the amount of oxygen gas consumed in a period of time. A. Primary productivity B. Gross primary productivity C. Net primary productivity D. Cellular respiration

D. Cellular respiration

Which of the following best describes the flow of energy in most terrestrial and near-surface marine ecosystems? A. Decomposers break down dead or decaying organisms to release energy and nutrients to be used by producers. B. Chemoautotrophs use inorganic energy sources, such as hydrogen sulfide, to create organic compounds from carbon dioxide. C. Apex predators feed on other organisms, which releases heat that can be used by producers and primary consumers. D. Producers use energy from the sun to make organic matter, such as sugars, from carbon dioxide and water and are then consumed by organisms higher in the food chain.

D. Producers use energy from the sun to make organic matter, such as sugars, from carbon dioxide and water and are then consumed by organisms higher in the food chain.

Hot temperatures, low rainfall, and consistent sunlight C. Cold temperatures, high rainfall, and inconsistent sunlight D. Warm temperatures, low rainfall, and inconsistent sunlight

A. Warm temperatures, high rainfall, and consistent sunlight
