Question

which organisms are decomposers in this food web? select all that apply. whirligig beetle bacteria golden algae water mold

Explanation:

To determine decomposers, we recall: Decomposers break down dead organic matter. Bacteria and water mold (fungi - like) are decomposers. Whirligig beetles are consumers (e.g., scavengers or predators), and golden algae are producers (photosynthetic). So the correct decomposers are bacteria and water mold. But based on the checked options, we analyze: Whirligig beetle is a consumer (not decomposer), golden algae is a producer. Bacteria and water mold are decomposers. However, if we follow the question's "select all that apply" with the given options (assuming the checkmarks are part of the problem's context, but correcting the biological classification): Decomposers in a food web are organisms that decompose dead material. Bacteria (prokaryotic decomposers) and water mold (fungal - like decomposers) are decomposers. Whirligig beetle is a consumer, golden algae is a producer. So the correct decomposers among the options are bacteria and water mold. But if we consider the original checkmarks (even if some are incorrect biologically), but biologically: Bacteria (decomposer), Water mold (decomposer). Whirligig beetle: consumer (e.g., eats other organisms), Golden algae: producer (photosynthesis). So the correct decomposers are bacteria and water mold.

Answer:

B. bacteria, D. water mold (assuming options are labeled as A. whirligig beetle, B. bacteria, C. golden algae, D. water mold)
