Question

all living organisms are made of carbon. carbon is also constantly being added to removed from the atmosphere. during photosynthesis, for example, plants extract from the atmosphere, along with water and sunlight, and turn it into sugar and ox for nourishment. as a result of photosynthesis, carbon is taken out of the atmosph contrast, burning fossil fuels such as oil and coal leads to the release of carbon int atmosphere in the form of carbon dioxide. carbon dioxide is a greenhouse gas tha as a blanket, trapping heat around earth. humans have burned so many fossil fuel there is more carbon dioxide in the atmosphere than there used to be. due to this increase in carbon dioxide, earth has become warmer.
match causes with their effects.
photosynthesis takes place. fossil fuels burn.
earth is warmer.
cause effect
carbon is removed from the atmosphere.
carbon enters the atmosphere.
an excess of carbon dioxide is present in the atmosphere.

Explanation:

1. From the text: "During photosynthesis...carbon is taken out of the atmosphere" → photosynthesis (cause) removes carbon (effect).
2. From the text: "burning fossil fuels...leads to the release of carbon into the atmosphere" → fossil fuel burning (cause) releases carbon (effect).
3. From the text: "more carbon dioxide...Earth has become warmer" → excess CO₂ (cause) warms Earth (effect).

Answer:

• Cause: Photosynthesis takes place. ; Effect: Carbon is removed from the atmosphere.
• Cause: Fossil fuels burn. ; Effect: Carbon enters the atmosphere.
• Cause: An excess of carbon dioxide is present in the atmosphere. ; Effect: Earth is warmer.
