What is the difference between oceanography and marine biology?

• Oceanography studies the physical and chemical properties of the ocean, while marine biology studies the organisms living in the ocean.

• Oceanography studies marine organisms, while marine biology studies the physical properties of the ocean.

• Oceanography and marine biology are the same fields.

• Oceanography focuses on freshwater bodies, while marine biology focuses on saltwater bodies.

What is the difference between biotic and abiotic? Give examples.

• Biotic refers to non-living things, while abiotic refers to living things.

• Biotic refers to living things, while abiotic refers to non-living things.

• Biotic and abiotic both refer to living things.

• Biotic and abiotic both refer to non-living things.

What is environment?

• The study of stars and planets.

• The surroundings or conditions in which an organism lives.

• The study of human anatomy.

• The study of ancient civilizations.

What is an organism’s niche?

• The physical space an organism occupies.

• The role or function of an organism in its ecosystem.

• The genetic makeup of an organism.

• The lifespan of an organism.

What is homeostasis?

• The process by which organisms maintain a stable internal environment.

• The process by which organisms change their external environment.

• The process by which organisms reproduce.

• The process by which organisms migrate.

What are the 3 zones that an organism might encounter when trying to maintain homeostasis.

• Terrestrial, aquatic, and aerial zones.

• Optimal Range, Zone of Stress, Zone of Intolerance

• Light, dark, and twilight zones.

• Urban, rural, and suburban zones.

Which of the following are ways sunlight affects marine organism distribution?

• Temperature regulation, photosynthesis, and vision.

• Sound propagation, pressure changes, and nutrient cycling.

• Water currents, tidal movements, and wave action.

• Salinity levels, oxygen availability, and sediment deposition.

What is the difference between ectotherms and endotherms?

• Ectotherms regulate their body temperature internally, while endotherms rely on external sources.

• Ectotherms rely on external sources to regulate their body temperature, while endotherms regulate their body temperature internally.

• Ectotherms and endotherms both rely on external sources to regulate their body temperature.

• Ectotherms and endotherms both regulate their body temperature internally.

What does it mean when an organism is in optimal range of environmental factors?

• The range of environmental factors are not good for the organism.

• They use too much energy in trying to maintain homeostasis that they can not survive

• They use an excess of energy in trying to maintain homeostasis and become stresses

• They use very little energy to maintain homeostasis
