global final

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.
