1. Chapter 3 Review

2. The zone where no organisms can tolerate • The zone where only a few organisms can tolerate • The range where an abundant number of organisms reside is the _________

3. Organisms that resemble each other physically and genetically, and can produce fertile offspring • A (n) _________ consists of all different species in an area interacting with each other.

4. The formula for glucose is ______________. • Most of the solar energy that passes through the atmosphere is: • Only _____% of solar energy is ever processed by plants.

5. What are the three major components that sustain life on earth? • What are the 4 spheres of lifecomponents? • Within the biosphere the atmosphere contains 78% of breathable ______________.

6. ______________ is a limiting factor specific to aquatic life zones. Its depletion creates Dead Zones when too much nitrogen is applied. • The ______________________ states that too much or too little of any abiotic factor can limit or prevent the growth of a population, even if all other factors are at or near the optimal range of tolerance. • Limiting factors that are dependent on populations are ___________.

7. What are the four component of Biological Diversity? • Ecologists studying the effects of pollution in the Chattahoochee notice a population of raccoons has begun to be reduced in numbers. This is an example of a reduction in what type of diversity?

8. ____________ occurs when infrared radiation from the sun increases the kinetic energy of atmospheric gases. This warms the atmosphere and the surface of the planet allowing life to exist. • Consistent weather patterns in a specific area over 30 years’ time is ____________

9. Since 1900 the global CO2 output has increased as populations have also increased

10. In the diagram, which trophic level contains the secondary consumers?

11. Refer to the illustration on the previous slide. How much energy is available to the organisms in level C? • A dead zone is reduced in the amount of biomass in an ecosystem and, in turn, reduces the % of available and useable energy that is transferable to the next Tropic Level. This reduction, measured by %, is of __________________.

12. The percentage of useable energy transferred as biomass from one Trophic level to another is called ____________ and is represented by the 10 % rule on a Trophic Pyramid. • If the producer level contained 5600 KC of energy, how much energy would the secondary consumers be able to get?

13. A population of frogs began to show signs of disorientation by not eating. Biologists captured them and measured each frog for its toxicity. The accumulation of toxins in individual organisms is a measurement of _____________________. • Inherited trait that increases an organisms chances of survival is _____________.

14. The addition of fertilizers is reaping havoc on ecosystems causing ponds and lakes to go into succession too quickly by ___________________: a usually naturally occurring event that creates too much algae and bacteria, depleting dissolved oxygen, which kills off fish. • Net primary productivity measures the amount of biomass producers can provide for consumers. The formula for determining NPP is: _________________________.

15. The process by which bacteria takes useable nitrogen in the soil and returns it to the atmosphere is _______________. • Fossil fuels are taken from ________ and as it combusted it contributes to the _______________.
