| Question | Answer |
|---|---|
| Define biotic. | A living thing in the biosphere. |
| Define abiotic. | Abiotic is non living. |
| Put these in smallest to largest: biome, population, organism, and community. | Organism, population, community, and biome. |
| Why is biodiversity important? | It is because as soon as one extinction occurs, the genetic material is gone forever. |
| What is succession ? | The slow and orderly replacement of community replacement. |
| The role of a species in an ecosystem is what? | Niche. |
| What are autotrophs called ? | Self-feeders or consumers. |
| What percent of available energy in any step in a food chain is passed on to the next step ? | 10% |
| Waves that cause the particles in a medium vibrate to both sides of the wave are called what ? | Longitudinal waves. |
| Define rarefraction. | The stretched out areas of a wave. |
| Define reflection. | Bouncing back of a wave when it hits something. |
| Define refraction. | The bending of light. |
| Waves which have particles that move perpendicular to the wave's vibrate from their resting point. | Transverse waves. |
| What is the wave height ? | The difference between a crest and an incoming trough. |
| What do you call the highest point of the wave and the lowest ? | The highest point is the wave crest and the lowest is the trough. |
| What is the wavelength ? | The distance from two equal points on the wave. |
| What kind of waves are sound waves ? | Longitudinal. |
| What kind of waves are ocean waves ? | Transverse. |
| The angle of incidence is equal to the angle of what ? | Reflection. |
| What are four things that are common to all waves ? | Wavelength, frequency, amplitude, velocity. |
| What is the waves frequency ? | # of wave crests/trough that pass a point in a given period of time after the first crest/trough. |
| What is a waves period ? | The time it takes for 1 full wavelength to pass. |
| What kind of waves can travel without a medium ? | Electromagnetic. |
| True or False: Electromagnetic waves travel at the same speed. | True. |
| Speed = what ? | frequency X wavelength. |
| What is the wave amplitude ? | It's half the wave's height. |
| What happens in cellular respiration ? | Process when mitochondria break down food molecules to produce ATP. |
| What are the 3 stages in cellular respiration? | Glycolysis, citric acid cycle, and the electron transport chain. |
| What is anaerobic ? | No oxygen is required. |
| What is aerobic ? | Requires oxygen. |
| Describe what happens in photosynthesis. | Energy from the sun stored in glucose, oxygen is given off and it produces sugar.It requires light only in presence of chlorophyll. |
| Describe what happens in cellular respiration. | Energy of glucose released and carbon dioxide is given off. Produces CO2 and H2O and it doesn't require light and occurs in all living cells. |
| Put these in largest to smallest: Infrared, visable, x-rays, gamma ray, radio waves, ultra violet. | Radio waves, infrared, visible, ultra violet, x-rays, gamma ray. |
| What does the light dependent stage do in photosynthesis ? | It traps suns energy and produces ATP without energy expense by the plant. |
| What does the light independent stage do in the photosynthesis ? | Where you put sugar. |
