Which statement correctly describes the relationship between the equations for photosynthesis and cellular respiration?

The equation for cellular respiration is the opposite of the photosynthesis equation.

The equation for cellular respiration is identical to the photosynthesis equation.

The equation for cellular respiration does not involve glucose or oxygen.

The equation for cellular respiration only produces water and ATP.

What is the main purpose of cellular respiration in living organisms?

To store energy in the form of ATP

To release oxygen into the atmosphere

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

It releases carbon dioxide into the atmosphere.

It releases oxygen into the atmosphere.

It has no effect on the atmosphere.

It reduces the amount of carbon compounds in the atmosphere.

What role do decomposers play in the carbon cycle?

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

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

They consume carbon dioxide from the atmosphere for energy.

They convert carbon dioxide into oxygen through photosynthesis.

How do animals contribute to the carbon cycle through digestion?

They incorporate carbon molecules into their cells and tissues.

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

They convert carbon molecules into oxygen for respiration.

They eliminate carbon molecules completely from the ecosystem.

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

It creates a Greenhouse Effect and leads to Global Warming.

It decreases the amount of carbon dioxide in the atmosphere.

It increases the amount of oxygen in the atmosphere.

It has no significant impact on the environment.

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

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

It increases the amount of oxygen in the atmosphere.

It provides more habitats for organisms.

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

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

Because plants absorb CO2 to use in photosynthesis.

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

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

Because plants normally convert CO2 into other chemicals.

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

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

The absorption of CO2 from the atmosphere.

The increase of habitats for organisms.

The decrease of oxygen in the atmosphere.

Which of the following is the correct equation for PHOTOSYNTHESIS?

CO 2 +light+H 2 O --> O 2 + glucose

CO 2 + glucose + H 2 O --> O 2 + light

O2 + light + H 2 O --> CO 2 + Glucosg

CO 2 + O 2 + H 2 O --> Light+ glucose

Which of the following is correct?

There is as much carbon on earth as when it was formed

Carbon is being created whenever it is recycled

Carbon is lost every time it is recycled

Carbon changes to different forms and is never recovered

Deforestation contributes to the greenhouse gasses by

loss of trees that would otherwise remove carbon dioxide from the air

as trees are cut, they release carbon dioxide

increasing the amount of oxygen in the air

underground in soil and fossil fuels
