Biodiversity 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 is biodiversity?

The variety of living things, genes, and habitats in a place.

Name the three levels of biodiversity.

Genetic diversity, species diversity, and ecosystem (habitat) diversity.

What does high biodiversity tell you about an ecosystem?

It has many different species and is more stable and resilient.

What is species richness?

The number of different species in an area.

What is genetic diversity and why is it important?

Differences in genes within a species; it helps populations adapt to change.

Give two human activities that can reduce biodiversity.

Habitat destruction (e.g., deforestation) and pollution (air, water, or land).

What is habitat loss and how does it affect biodiversity?

When habitats are removed or broken up; fewer species can live there.

How can climate change affect biodiversity?

Changing temperature and rainfall can force species to move or die out.

What is extinction?

When the last individual of a species dies; that species is gone forever.

What is meant by local and global biodiversity?

Local is variety in a small area; global is variety across the world.
