Maya wrote a few steps to describe how carbon circulates between the atmosphere and living organisms. step 4 is missing.

step 1: carbon enters the atmosphere as carbon dioxide from respiration and combustion
step 2: plants use carbon dioxide to make glucose
step 3: plant-eating animals consume the glucose present in plants
step 4:

which of the following best describes step 4?

carbon dioxide in the atmosphere is used by plants for photosynthesis.

carbon dioxide in the atmosphere is converted into glucose by animals.

dead animals decompose and recycle the carbon in the form of oxygen and water.

dead animals are buried and form fossil fuels, which produce carbon dioxide when burned.

The answer is; Dead animals are buried and form fossil fuels, which produce carbon dioxide when burned.

When animals and plants are fossilized and buried under sediments, the higher pressure and temperatures turns them to oil, over time, that is mined and combusted for energy by humans. This plays a significant  role in the carbon cycle.

events in order:

1.       vishnu schist

2. zoroaster granite

3. bass limestone

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.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
