Habitats and Ecosystems 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 habitat?

A habitat is the place where an organism lives.

Give two examples of habitats.

Two examples of habitats are a woodland and a pond.

What is an ecosystem?

An ecosystem is all the living things in an area and the non-living parts of the environment that affect them.

How is an ecosystem different from a habitat?

A habitat is the place where an organism lives, while an ecosystem includes that place plus all the living things there and the non-living conditions.

What are biotic factors in a habitat?

Biotic factors are the living parts of a habitat, such as plants, animals, fungi and bacteria.

What are abiotic factors in a habitat?

Abiotic factors are the non-living parts of a habitat, such as temperature, light, water, soil type and pH.

What is a microhabitat? Give one example.

A microhabitat is a very small part of a habitat with its own conditions, for example under a stone or in the bark of a tree.

Why do organisms need a suitable habitat to survive?

A suitable habitat provides the right food, water, shelter and conditions, such as temperature, that an organism needs to live and reproduce.

Give one example of a small ecosystem and one example of a large ecosystem.

A pond is an example of a small ecosystem, and a rainforest is an example of a large ecosystem.

How can a change in an abiotic factor like temperature affect an ecosystem?

A change in temperature can help some organisms and harm others, which can change which species live there and how many of them there are.
