Impact of Environmental Change 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 are some environmental factors that affect the distribution of organisms?

Temperature, availability of water, and composition of gases in the atmosphere.

How does temperature affect the distribution of organisms?

Organisms have adaptations for specific temperature ranges. Changes in temperature can affect food availability and cause organisms to migrate or face extinction.

What is desertification?

Desertification is the process by which fertile land becomes desert, often due to changes in temperature affecting plant growth.

How does water availability impact organisms in an ecosystem?

Water is essential for all organisms and plants. Changes in water availability can lead to migration and affect the whole food web and ecosystem.

How does the composition of gases in the atmosphere influence the distribution of organisms?

Greenhouse gases contribute to global warming. Pollutants like sulphur dioxide affect sensitive species, such as lichen, leading to their decline in polluted areas.

Why are wildebeest migrations important in North Africa?

Wildebeest migrate long distances following rainfall patterns in search of fresh grazing land and water. This illustrates the impact of water availability on organism distribution.
