Parasitism and Mutualism 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 parasitism?

Parasitism is a symbiotic relationship where the parasite lives within or on a larger organism (the host), benefiting by taking nutrients, while the host suffers harm and gets no benefit.

Give an example of a parasitic relationship in humans.

An example is the tapeworm, which lives inside the human gut and ‘steals’ nutrients from the host, potentially leading to malnutrition.

What is mutualism?

Mutualism is a type of symbiotic relationship in which both species involved benefit from their interaction, such as through the exchange of nutrients.

Give an example of a mutualistic relationship.

An example is the relationship between flowers and bees.

Bees get nectar from flowers for food, and in the process, they spread the flower’s pollen, which helps plant reproduction.

How do bees benefit from their mutualistic relationship with flowers?

Bees benefit by getting nectar from the flowers, which they use for food.

How do flowers benefit from their mutualistic relationship with bees?

Flowers benefit because bees spread their pollen to other flowers, which helps with plant reproduction.
