Biomes: Worksheet | PDF - Free Printable

Let’s go slide by slide and answer each question clearly.

Slide 2:

1. Ecosystem is short for what, and what does it include?
→ “Ecosystem” is short for “ecological system.”
→ It includes all living things (like plants, animals, microbes) AND non-living things (like soil, water, air, sunlight) in a specific area that interact with each other.

2. How many ‘ecosystems’ do we have? Name them.
→ There are many ecosystems — too many to count exactly! But scientists often group them into major types like:
- Forests
- Grasslands
- Deserts
- Oceans
- Freshwater (rivers, lakes)
- Tundra
- Wetlands
*(Note: The number isn’t fixed — it depends on how you classify them. For school purposes, listing 5–7 main ones is fine.)*

3. Name ‘the living organisms’.
→ Living organisms = biotic factors. Examples: trees, deer, bacteria, birds, fish, insects, fungi.

4. An ‘Ecosystem’s Development’ depends on what?
→ It depends on:
- Climate (temperature, rainfall)
- Soil type
- Sunlight
- Water availability
- Interactions between living things (like predation, competition, symbiosis)

Slide 3 & 5:

What are the five (5) environmental systems of the Human Ecosystem?
*(This likely refers to the 5 spheres or subsystems that make up Earth’s environment that humans interact with.)*

They are:
1. Atmosphere (air)
2. Hydrosphere (water)
3. Lithosphere (land/rocks/soil)
4. Biosphere (living things)
5. Anthroposphere (human-made systems — cities, farms, technology)

*Sometimes “Cryosphere” (ice) is included instead of anthroposphere, but since this says “Human Ecosystem,” anthroposphere fits better.*

Give an example of each. Use the table below:

| 1 | 2 | 3 | 4 | 5 |
|---------------|-------------|--------------|------------|-----------------|
| Atmosphere | Hydrosphere | Lithosphere | Biosphere | Anthroposphere |
| Air we breathe| Rivers | Soil | Trees | Cities |

*(You can swap examples — e.g., oceans for hydrosphere, rocks for lithosphere, animals for biosphere, roads for anthroposphere.)*

Slide 6 – Fill in the gaps:

> Biomes are the d__________ r__________ found on our p__________ which can be distinguished by their t__________, climate and biological d__________ (variety).

Fill-ins:
- different
- regions
- planet
- temperature
- diversity

So full sentence:
→ *Biomes are the different regions found on our planet which can be distinguished by their temperature, climate and biological diversity (variety).*

> Biomes are a way to divide the Earth’s surface into what three (3) areas?

Answer:
Actually, biomes are usually divided based on climate, vegetation, and animal life — but if they mean geographic zones, sometimes it’s:

→ Land, Water, and Ice (but that’s not standard).

Wait — more accurately, biomes are grouped into:

1. Terrestrial (land-based)
2. Aquatic (water-based) → which splits into freshwater and marine
But the question says “three areas” — so perhaps:

→ Forests, Grasslands, Deserts? No, those are biome types.

Actually, looking at common curriculum:
Some sources say biomes divide Earth into:

1. Polar
2. Temperate
3. Tropical

OR

1. Land
2. Freshwater
3. Marine

Since the next slide asks for 5 biomes, and this says “divide into 3 areas”, it’s likely referring to:

→ Terrestrial, Freshwater, Marine

That’s the most logical trio.

So final fill-in for that part:
→ *Biomes are a way to divide the Earth’s surface into what three (3) areas?*
Answer: Terrestrial, Freshwater, Marine

Slide 7:

Many agree on five (5) biomes. They are?

Commonly accepted 5 major biomes:

1. Forest
2. Grassland
3. Desert
4. Tundra
5. Aquatic (or sometimes split as Freshwater + Marine, but here it’s one)

Alternatively, some list:

1. Tropical Rainforest
2. Savanna
3. Desert
4. Temperate Forest
5. Tundra

But since it says “five biomes” generally, the broad categories are:

→ Forest, Grassland, Desert, Tundra, Aquatic

Use the table:

| 1 | 2 | 3 | 4 | 5 |
|---------|----------|--------|--------|----------|
| Forest | Grassland| Desert | Tundra | Aquatic |

*(Aquatic can also be called “Water Biome” or split later — but for 5 total, this works.)*

Final Answer:

Slide 2:
- Ecosystem = ecological system; includes living + non-living things interacting.
- Many ecosystems exist — e.g., forest, desert, ocean, grassland, tundra.
- Living organisms: plants, animals, bacteria, fungi.
- Ecosystem development depends on climate, soil, water, sunlight, and species interactions.

Slide 3 & 5:
Five environmental systems of Human Ecosystem:
1. Atmosphere → Example: Air
2. Hydrosphere → Example: Rivers
3. Lithosphere → Example: Soil
4. Biosphere → Example: Trees
5. Anthroposphere → Example: Cities

Slide 6:
Biomes are the different regions found on our planet which can be distinguished by their temperature, climate and biological diversity.
Biomes divide Earth’s surface into: Terrestrial, Freshwater, Marine

Slide 7:
Five biomes:
1. Forest
2. Grassland
3. Desert
4. Tundra
5. Aquatic
