Adaptations, Interdependence and Competition 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 meant by an adaptation?

A feature or behaviour that helps an organism survive and reproduce in its habitat.

Name the three types of adaptation.

Structural, behavioural and functional (physiological).

What is a structural adaptation? Give one example.

A body feature that helps survival, for example thick fur to keep warm.

What is a functional (physiological) adaptation? Give one example.

A process inside the body that helps survival, for example producing very concentrated urine to save water.

What is an extremophile?

A microorganism that lives in extreme conditions, such as very high temperature, pressure or salt levels.

What do plants compete for?

Light, space, water and mineral ions from the soil.

What do animals compete for?

Food, mates and territory.

What does interdependence mean in a community?

Organisms rely on each other for things like food, shelter, pollination and seed dispersal.

In biology, what is a community?

All the populations of different species living in the same habitat.

What is a stable community?

A community where population sizes and environmental factors stay fairly constant over time due to interdependence.

Name two abiotic factors that can affect a community.

Light intensity and temperature.

Name two biotic factors that can affect a community.

Availability of food and new predators.
