Question 28
1. Earthworms
2. Jellyfish
3. Millipedes
4. Seahorses
5. Woodlice
Select the correct answer using the code given below.
AOptions
BSolution
Detritivores are organisms that feed on dead organic matter, including decaying plants and animals, and their waste products. They play a crucial role in decomposition and nutrient cycling.
1. Earthworms: These are classic examples of detritivores, consuming decaying organic matter in the soil and aiding in its breakdown and aeration.
2. Jellyfish: Jellyfish are typically carnivorous, preying on small fish, zooplankton, and other invertebrates.
3. Millipedes: Millipedes primarily feed on decaying plant matter, making them detritivores.
4. Seahorses: Seahorses are carnivores, feeding on small crustaceans and other tiny invertebrates.
5. Woodlice: Also known as pill bugs or sow bugs, woodlice feed on decaying wood and other plant debris, classifying them as detritivores.
Therefore, earthworms, millipedes, and woodlice are detritivores.
CStrategy
To answer questions about ecological roles, clearly define the term (e.g., detritivore, producer, consumer). Then, recall examples of organisms and their primary diets. Systematically evaluate each option against the definition to arrive at the correct combination.
