"People in Albany and New York City are using “green roofs” to improve the environment. A green roof can be added to many buildi

ngs that have large, flat roofs. Green roofs have three parts: a protective layer to separate plant roots from the roof of the building, an absorptive layer to catch and hold rainwater, and a layer of plants. Often, green roofs use Sedum, a short, desert plant, because it is efficient at storing water in its leaves and can withstand the colder climate.
A green roof saves energy, reduces carbon dioxide in the atmosphere, and prevents rainwater and melting snow from overloading sewer systems. It can also protect the roof of a building from damage. However, green roofs can be expensive to install, and require care and maintenance.

State one reason why it is important to reduce the amount of carbon dioxide in the atmosphere."

This information cannot be obtained from the text, and we need to access general knowledge: why carbon dioxide is harmful to the environment.

It is harmful, for example, because it is one of the greenhouse gases, that is a gas that traps the heat in the Earth's atmosphere and leads to a warming up of our planet (global warming). Earth's temperature should be balanced, because any changes can have catastrophic effects: warming of the planet leads to the melting of ice caps and can cause floods, for example

Kruka [31]

The items needed to complete a circuit include the following:

  • Wire
  • Battery
  • Load
  • Switch

<h3>Functions of the parts of a Circuit.</h3>

The wire helps in the distribution of the electric current from the power

source in order to ensure it gets to the load.

The battery contains compounds which is responsible for providing the

energy required to power up the load.

The load could be a bulb, fan etc and is the final destination of the electric

current. The electric current powers up the load and makes it functional.

The switch helps to regulate the flow of electric current and has an 'on and

off button' to prevent energy wastage when not in use.
