Trophic Levels 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 food chain?

A food chain shows the feeding relationships in a specific ecosystem, illustrating the direction of biomass transfer between trophic levels.

What are trophic levels in a food chain?

Trophic levels represent the stages in a food chain: producers (level 1), primary consumers (level 2), secondary consumers (level 3), and tertiary consumers (level 4).

Who are the producers in a food chain?

Producers are photosynthetic organisms, like plants or algae, that use the Sun’s energy to perform photosynthesis and produce biomass.

What role do primary consumers play in a food chain?

Primary consumers are herbivores or omnivores that eat producers.

For example, in the food chain Grass → Grasshopper → Bird → Snake, the grasshopper is the primary consumer.

Who are decomposers and what is their role?

Decomposers, such as bacteria and fungi, break down dead or decaying organic matter, returning nutrients to the environment and supporting ecosystem health.

What is an apex predator?

An apex predator is a carnivore at the top of the food chain with no natural predators.

For example, the snake in the food chain Grass → Grasshopper → Bird → Snake could be considered an apex predator.
