Based on the chart, [blank] and [blank] are root feeders that consume plant roots.

**Question 2** **Incorrect** The provided answer states: "pathogens" and "parasites" are root feeders that consume plant roots. Explanation: The terms "pathogens" and "parasites" are highlighted in labeled boxes, indicating that they were chosen as answers in a question related to biology or plant science. The question's topic seems to involve identifying organisms that feed on plant roots. However, the response is marked as incorrect, suggesting that another pair of terms would correctly identify root feeders in this context.

# Types of Soil Organisms and Their Major Functions ## Photosynthesizers - **Organisms**: Plants, algae, bacteria - **Functions**: - **Capture energy** - Use solar energy to fix CO2 - Add organic matter to soil ## Decomposers - **Organisms**: Bacteria and fungi - **Functions**: - **Break down residue** - Retain nutrients in their biomass - Bind soil aggregates - Convert nitrogen ## Mutualists - **Organisms**: Bacteria and fungi - **Functions**: - **Enhance plant growth** - Protect plants from disease - Fix nitrogen for plants - Symbiotic relationships that assist with nutrient delivery ## Pathogens and Parasites - **Organisms**: Bacteria and fungi, nematodes and micro-arthropods - **Functions**: - **Promotes disease** - Consume healthy roots - Parasitize other nematodes or insects ## Root Feeders - **Organisms**: Nematodes and macro-arthropods - **Functions**: - **Consume plant roots** - Cycle organic material - Can cause crop yield loss ## Bacterial or Fungal Feeders - **Organisms**: Protozoa and nematodes, nematodes and micro-arthropods - **Functions**: - **Graze** - Release nitrogen from bacteria or fungi for plant use - Control root-feeding or disease bacteria or fungal pests ## Shredders - **Organisms**: Earthworms and macro-arthropods - **Functions**: - **Break down residue and build soil structure** - Shred plant litter - Guts and fecal pellets provide habitat for bacteria - Enhance soil structure through burrowing ## Higher-level Predators - **Organisms**: Nematode-feeding nematodes, large arthropods (e.g., mice, voles, shrews, birds, etc.) - **Functions**: - **Control populations** - Consume lower trophic level predators and control population - Improve soil structure through burrowing - Larger organisms can carry smaller ones to other locations This chart outlines various types of soil organisms and their primary ecological functions, from
