Interdependency in Tropical Rainforests 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 are the biotic components of Tropical Rainforests (TRFs)?

The biotic components include vegetation (high biodiversity of plants) and animals (variety of species such as mammals, insects, reptiles and birds).

What are the abiotic components of Tropical Rainforests (TRFs)?

The abiotic components include the climate (high temperatures and rainfall) and the soil (largely infertile due to leaching).

Why is the nutrient cycle important in Tropical Rainforests (TRFs)?

The nutrient cycle provides essential nutrients for plant growth, maintaining ecosystem balance.
Decomposition of organic matter replenishes topsoil nutrients, despite rapid leaching.

Give an example of interdependence in Tropical Rainforests (TRFs).

The Brazil nut tree and the agouti have a mutual relationship.
The agouti disperses the tree’s seeds by gnawing open hard shells, while the agouti relies on the nuts for sustenance.

What is leaching and how does it affect TRFs?

Leaching is the process of rainwater washing nutrients away from the soil, making the soil largely infertile despite its depth.

Define “interdependent” in the context of Tropical Rainforests (TRFs).

Interdependent means that all components of the ecosystem, both biotic and abiotic, are mutually dependent on each other for the ecosystem to function properly.
