Desert Ecosystem Worksheets & Facts | Inhabitants, Significance - Free Printable

Let's go through each statement one by one and determine whether it is TRUE or FALSE based on the facts about desert ecosystems. We'll follow the instructions:
- If the statement is true, circle the cactus.
- If the statement is false, circle the camel and correct the incorrect word/phrase.

---

1. The cold desert ecosystem experiences snow sometimes.

✔ TRUE
Cold deserts (like those in Central Asia or parts of North America) can have snowfall during winter.
👉 Circle the cactus.

---

2. Deserts are also sources of petroleum and other minerals.

✔ TRUE
Many deserts, such as the Arabian Desert, contain large oil reserves. Deserts are often rich in minerals due to geological processes and erosion.
👉 Circle the cactus.

---

3. The wind velocity is very low in deserts.

✘ FALSE
Wind velocity in deserts is often high, especially during dust storms. The lack of vegetation means less resistance to wind.
👉 Circle the camel, and write "high" over "very low".

---

4. The desert is extremely hot during the day and equally hot during the night.

✘ FALSE
Deserts are extremely hot during the day but very cold at night due to lack of moisture and cloud cover to retain heat.
👉 Circle the camel, and write "cold" over "equally hot".

---

5. Thorny shrubs easily die in deserts.

✘ FALSE
Thorny shrubs (like acacias) are well-adapted to desert conditions and survive well. Their thorns deter herbivores, and they conserve water efficiently.
👉 Circle the camel, and write "survive" over "easily die".

---

6. The amount of rainfall is higher in the warm desert.

✘ FALSE
Warm deserts (like the Sahara) are among the driest places on Earth. Rainfall is very low, not higher. Cold deserts may receive slightly more precipitation, but still minimal.
👉 Circle the camel, and write "lower" over "higher".

---

7. Despite the low population density, the desert offers biodiversity.

✔ TRUE
Deserts support unique flora and fauna adapted to extreme conditions (e.g., camels, lizards, cacti). Biodiversity exists even if species richness is lower than in tropical regions.
👉 Circle the cactus.

---

8. Deserts do not offer artifacts because of its setting.

✘ FALSE
Deserts do preserve artifacts well due to dry conditions that prevent decay. Many archaeological sites (e.g., Egypt, Mesopotamia) are in deserts.
👉 Circle the camel, and write "do" over "do not".

Final Answers Summary:

| Statement | Verdict | Action |
|---------|--------|--------|
| 1. Cold desert has snow sometimes. | ✔ TRUE | Circle cactus |
| 2. Deserts have petroleum/minerals. | ✔ TRUE | Circle cactus |
| 3. Wind velocity is very low. | ✘ FALSE | Circle camel, write high |
| 4. Hot day and equally hot night. | ✘ FALSE | Circle camel, write cold |
| 5. Thorny shrubs easily die. | ✘ FALSE | Circle camel, write survive |
| 6. Rainfall is higher in warm desert. | ✘ FALSE | Circle camel, write lower |
| 7. Low population, but biodiversity. | ✔ TRUE | Circle cactus |
| 8. Deserts do not offer artifacts. | ✘ FALSE | Circle camel, write do |

---

✔ Corrected Version of False Statements:
- The wind velocity is high in deserts.
- The desert is extremely hot during the day and cold during the night.
- Thorny shrubs survive in deserts.
- The amount of rainfall is lower in the warm desert.
- Deserts do offer artifacts because of its setting.
