The Interdependency of Hot Deserts Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What does interdependency mean in an ecosystem?

Interdependency means that the biotic (living) and abiotic (non-living) components of an ecosystem rely on each other for survival.
Changing one aspect can have dramatic consequences for others.

What is the role of vegetation in a hot desert food web?

Vegetation in hot deserts use energy from the sun to grow and provide energy for primary consumers like rodents and insects.

How can the use of pesticides affect the desert ecosystem?

Excessive use of pesticides can introduce chemicals into the ecosystem, affecting insect populations. This disrupts the food web, impacting birds and other animals that rely on insects for food.

How have the Bedouin adapted to life in the desert?

The Bedouin live in tents made from camel hair and vegetable fibres, manage livestock for food, and wear clothing designed to protect against heat. Their lifestyle is adapted to the harsh desert conditions.

What makes the nutrient cycle in hot deserts unique?

In hot deserts, litter decomposes very slowly due to extreme temperatures and lack of rainfall. Most nutrients are stored in the soil, and the transfer of nutrients is slow, promoting slow plant growth.

What is the significance of the nutrient cycle in hot deserts?

Despite the slow decomposition, the nutrient cycle is crucial for the ecosystem’s functioning. It supports vegetation, which primary consumers rely on, and maintains the limited biodiversity in the desert.
