Impact of Changing One Component of an Ecosystem 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 a stable ecosystem?

A stable ecosystem maintains its structure and function over time, with balanced interactions between biotic (living) and abiotic (non-living) components, ensuring biodiversity and proper functioning.

What are examples of natural events that can disrupt an ecosystem?

Natural events that can disrupt an ecosystem include wildfires, floods, the introduction of a new species, diseases, drought, landslides, and natural climate change.

What human activities can alter a stable ecosystem?

Human activities that can alter a stable ecosystem include hunting, deforestation, introducing invasive species, removing plants, diverting water supplies, using chemicals, manmade fires, and human-induced climate change.

What is the ripple effect in an ecosystem?

The ripple effect in an ecosystem refers to how changes, such as deforestation, can cause a series of impacts that spread out, affecting various species and components within the ecosystem.

What happens to a deciduous woodland ecosystem if deforestation occurs?

Deforestation in a deciduous woodland can lead to the loss of insects that rely on trees, the decline of beetles, robins, and sparrow hawks due to food shortages, and overall disruption of the food web, causing species to die out or relocate.

Define the term “deciduous woodland.”

Deciduous woodland is a type of ecosystem or biome that contains trees with broad leaves that shed annually, typically found in temperate regions with distinct seasonal variations.
