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 interdependence in an ecosystem?

Interdependence is the relationship where species within a community rely on each other for survival. Changes in the population of one species can significantly affect other species in the ecosystem.

How does a decline in the population of birds affect the grass and grasshopper populations in a simple food chain?

If the population of birds declines, the grasshopper population will increase, which in turn will decrease the quantity of grass due to more grasshoppers consuming it.

What are the two types of competition in an ecosystem?

The two types of competition are:

• Interspecific competition: between individuals of different species.

• Intraspecific competition: between individuals from the same species.

What resources do animals compete for in an ecosystem?

Animals compete for food, water, mates and territory.

What resources do plants compete for in an ecosystem?

Plants compete for light, water, space and mineral ions.

Why is competition important in an ecosystem?

Competition is important because it determines which organisms have access to the resources they need to survive and reproduce.

An organism with more resources is more likely to survive and reproduce.
