Question 11

What is the result of combustion of wood and fossil fuels according to the text?

Accepted Answer

It releases carbon dioxide into the atmosphere.

Answer

It releases oxygen into the atmosphere.

Answer

It has no effect on the atmosphere.

Answer

It reduces the amount of carbon compounds in the atmosphere.

Question 12

What role do decomposers play in the carbon cycle?

Accepted Answer

They break down dead organisms and release carbon dioxide into the atmosphere.

Answer

They release oxygen into the atmosphere by breaking down living tissue.

Answer

They consume carbon dioxide from the atmosphere for energy.

Answer

They convert carbon dioxide into oxygen through photosynthesis.

Question 13

Accepted Answer

They incorporate carbon molecules into their cells and tissues.

Answer

They break down carbon molecules to release them into the soil.

Answer

They convert carbon molecules into oxygen for respiration.

Answer

They eliminate carbon molecules completely from the ecosystem.

Question 14

What do many scientists believe is the result of burning large amounts of fossil fuels?

Accepted Answer

It creates a Greenhouse Effect and leads to Global Warming.

Answer

It decreases the amount of carbon dioxide in the atmosphere.

Answer

It increases the amount of oxygen in the atmosphere.

Answer

It has no significant impact on the environment.

Question 15

What is one of the consequences of deforestation mentioned in the text?

Accepted Answer

It takes away habitats from organisms that live in those areas.

Answer

It increases the amount of oxygen in the atmosphere.

Answer

It provides more habitats for organisms.

Answer

It decreases the amount of Carbon Dioxide in the atmosphere and increases oxygen.

Question 16

Why does CO2 stay in the air when we get rid of plants?

Accepted Answer

Because plants absorb CO2 to use in photosynthesis.

Answer

Because plants release O2 into the atmosphere as a waste product of photosynthesis.

Answer

Because the removal of plants increases the amount of oxygen in the atmosphere.

Answer

Because plants normally convert CO2 into other chemicals.

Question 17

What can't happen if there are no plants, according to the text?

Accepted Answer

The release of O2 into the atmosphere as a waste product of photosynthesis.

Answer

The absorption of CO2 from the atmosphere.

Answer

The increase of habitats for organisms.

Answer

The decrease of oxygen in the atmosphere.

Question 18

Which of the following is the correct equation for PHOTOSYNTHESIS?

Accepted Answer

CO₂+light+H₂O --> O₂+ glucose

Answer

CO₂+ glucose + H₂O --> O₂+ light

Answer

_O2+ light + H₂O --> CO₂+ Glucosg

Answer

CO₂+ O₂ + H₂O --> Light+ glucose
