Question

below is a food web from joshua tree national park, a desert ecosystem in southern california. which arrows show matter moving from a secondary consumer to a decomposer? select all that apply. the arrow between the kit fox and the coyote the arrow between the kit fox and the microfungus the arrow between the grasshopper and the grasshopper mouse the arrow between the grasshopper mouse and the coyote the arrow between the desert iguana and the kit fox

Explanation:

• First, identify secondary consumers in the food web. Secondary consumers eat primary consumers.
• Then, identify decomposers (microfungus in this case).
• Check each option:
• The arrow between the kit fox (a secondary consumer) and the microfungus (a decomposer) shows matter moving from a secondary consumer to a decomposer.
• The other options either show matter moving between consumers (e.g., kit fox and coyote, grasshopper and grasshopper mouse, grasshopper mouse and coyote, desert iguana and kit fox) or from a primary consumer to a secondary consumer (desert iguana is a primary consumer, kit fox is a secondary consumer in some chains but the key is the decomposer relation here).

Answer:

the arrow between the kit fox and the microfungus
