A student is developing a model of the carbon cycle. She wants to include an example that shows the interaction between the atmosphere and the geosphere.

Question

Which example would best show this interaction?

(1 point)
Responses

Fossil fuels being burned and releasing carbon dioxide into the air.
Fossil fuels being burned and releasing carbon dioxide into the air.

Animals inhaling oxygen and releasing carbon dioxide back into the air.
Animals inhaling oxygen and releasing carbon dioxide back into the air.

Fish dying in the ocean and decomposing on the ocean floor.
Fish dying in the ocean and decomposing on the ocean floor.

Plants undergoing photosynthesis to convert carbon dioxide into biomass.

Answer 1

The best example that shows the interaction between the atmosphere and the geosphere is:

Fossil fuels being burned and releasing carbon dioxide into the air.

This example highlights the interaction between carbon stored in the geosphere (in the form of fossil fuels) and the atmosphere, as burning fossil fuels releases carbon dioxide into the atmosphere.

Answer 2

Which process shows the uptake of carbon from the atmosphere to the biosphere?(1 point)
Responses

Diffusion
Diffusion

Decomposition
Decomposition

Photosynthesis
Photosynthesis

Cellular respiration

Answer 3

The process that shows the uptake of carbon from the atmosphere to the biosphere is:

Photosynthesis.

During photosynthesis, plants take in carbon dioxide from the atmosphere and convert it into organic compounds, effectively transferring carbon from the atmosphere to the biosphere.

Answer 4

What role do decomposers have in the carbon cycle?(1 point)
Responses

Decomposers use carbon to produce energy but do not release any as wastes.
Decomposers use carbon to produce energy but do not release any as wastes.

Decomposers convert atmospheric carbon dioxide into oxygen through photosynthesis.
Decomposers convert atmospheric carbon dioxide into oxygen through photosynthesis.

Decomposition locks carbon into soil
Decomposition locks carbon into soil

Decomposers release carbon dioxide into the atmosphere.

Answer 5

The correct response regarding the role of decomposers in the carbon cycle is:

Decomposers release carbon dioxide into the atmosphere.

Decomposers break down dead organic matter, and in this process, they release carbon dioxide back into the atmosphere, contributing to the carbon cycle.

Answer 6

How does cellular respiration affect the exchange of carbon between the biosphere and geosphere?(1 point)
Responses

Bacteria absorb carbon dioxide from the soil through respiration, reducing underground carbon.
Bacteria absorb carbon dioxide from the soil through respiration, reducing underground carbon.

Respiration increases the oxygen content in soil, enhancing decomposition by bacteria.
Respiration increases the oxygen content in soil, enhancing decomposition by bacteria.

Respiration allows bacteria to change stone into carbon dioxide.
Respiration allows bacteria to change stone into carbon dioxide.

Bacteria release carbon dioxide into the soil during respiration, increasing soil carbon levels.

Answer 7

The correct response regarding how cellular respiration affects the exchange of carbon between the biosphere and geosphere is:

Bacteria release carbon dioxide into the soil during respiration, increasing soil carbon levels.

During cellular respiration, bacteria and other organisms break down organic matter, releasing carbon dioxide into the soil, which can contribute to the carbon levels in the geosphere.

Answer 8

Which is a benefit of using a model?(1 point)
Responses

A model explains concepts that are difficult to show.
A model explains concepts that are difficult to show.

A model predicts conditions of future events.
A model predicts conditions of future events.

A model negates the need for further experimentation.
A model negates the need for further experimentation.

A model shows the all the events of a real phenomenon.

Answer 9

The correct benefit of using a model is:

A model explains concepts that are difficult to show.

Models simplify complex processes or systems, allowing for easier understanding and explanation of concepts that may be challenging to visualize or demonstrate accurately.

Answer 10

Answer 11

The correct term used to describe the process by which light energy from the sun is converted into chemical energy is:
