The figure shows an energy pyramid for an ecosystem. What happens to the amount of energy in the pyramid as it moves up through the different levels? A) It increases by a factor of about 10%. B) It decreases by a factor of about 90%. C) It increases by a factor of about 90%. D) It decreases by a factor of about 10%

B) It decreases by a factor of about 90%.

Explanation:

When we move in the upward direction in the energy pyramid of an ecosystem, the amount of energy is decreases. If a producer contains 100 % energy, so only 10 percent energy is transferred to the body of primary consumer and the rest 90 percent is lost as heat energy. And again when primary consumer is eaten by secondary consumer, only 10 percent of energy is transferred and the remaining energy is lost as heat energy and so on.

events in order:

1.       vishnu schist

4. hakatar   shale

5. igneous intrusion

6. shinumo quartzite

7. dox sandstone

8. tapeats limestone

9. bright angel shale

10. muav limestone

11. temple butte limestone

12. redwall limestone  

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
