Let's solve the paragraph step by step using the given words:
Given words:
- fossil
- buried
- light
- chemical
- sediments
- coal
- Plants
- photosynthesis
- Creatures
- oil
- sea
- natural gas
---
Now, let's fill in the blanks logically.
---
1. The Sun produces a great deal of ________ energy and heat energy.
The Sun emits
light energy (along with heat). So the correct word is:
>
light
✔ *The Sun produces a great deal of
light energy and heat energy.*
---
2. Some of this reaches the Earth. ________ can trap this energy and change it by a process called ________.
Plants use sunlight to perform
photosynthesis, which converts light energy into chemical energy.
So:
- First blank:
Plants
- Second blank:
photosynthesis
✔ *Some of this reaches the Earth.
Plants can trap this energy and change it by a process called
photosynthesis.*
---
3. Some of the energy becomes locked in them, in the form of ________ energy.
Plants store energy as
chemical energy through photosynthesis.
✔ *Some of the energy becomes locked in them, in the form of
chemical energy.*
---
4. Over many years, loads and loads of plants grew. Some were ________ underground.
Dead plants were
buried underground over time.
✔ *Some were
buried underground.*
---
5. Their energy became trapped as they were turned into ________.
Over time, buried plant matter turns into
coal.
✔ *Their energy became trapped as they were turned into
coal.*
---
6. ________ that fed on the plants fell to the bottom of the ________.
Creatures (animals) that ate the plants died and sank to the bottom of the
sea.
So:
- First blank:
Creatures
- Second blank:
sea
✔ *Creatures that fed on the plants fell to the bottom of the
sea.*
---
7. They were buried under ________ and chemical changes occurred to make ________ and ________.
After death, creatures were buried under
sediments. Over millions of years, pressure and heat cause chemical changes forming
oil and
natural gas.
So:
- First blank:
sediments
- Second blank:
oil
- Third blank:
natural gas
✔ *They were buried under
sediments and chemical changes occurred to make
oil and
natural gas.*
---
8. We call fuels formed from living things in this way ________ fuels.
These are called
fossil fuels.
✔ *We call fuels formed from living things in this way
fossil fuels.*
---
✔ Final Filled Paragraph:
The Sun produces a great deal of
light energy and heat energy.
Some of this reaches the Earth.
Plants can trap this energy and change it by a process called
photosynthesis. Some of the energy becomes locked in them, in the form of
chemical energy.
Over many years, loads and loads of plants grew. Some were
buried underground. Their energy became trapped as they were turned into
coal.
Creatures that fed on the plants fell to the bottom of the
sea. They were buried under
sediments and chemical changes occurred to make
oil and
natural gas. We call fuels formed from living things in this way
fossil fuels.

🔍 Explanation:
This paragraph explains how
fossil fuels (coal, oil, natural gas) are formed:
- The Sun provides
light energy.
-
Plants use
photosynthesis to convert this into
chemical energy.
- When plants and animals die, they get
buried under
sediments.
- Over millions of years, heat and pressure turn them into
coal,
oil, and
natural gas.
- These are collectively known as
fossil fuels because they come from
fossilized remains of ancient life.
All the words used fit perfectly in context and follow scientific understanding.
