Question

a corn field includes corn plants, mice, hawks, and various insects, fungi, and bacteria. which nutritional role is correctly paired with organisms that carry out that role?
1 heterotrophs - corn and bacteria
2 producers - insects and fungi
3 consumers - mice and insects
4 decomposers - hawks and bacteria
submit answer
listen

Explanation:

• Producers are organisms that can make their own food through photosynthesis (like corn plants) or chemosynthesis. Insects are consumers (they eat plants or other organisms) and fungi are decomposers (break down dead organic matter). So the pair “producers - insects and fungi” is incorrect.
• Heterotrophs are organisms that cannot make their own food and rely on other organisms for nutrition. Corn is a producer (autotroph) as it can photosynthesize, so “heterotrophs - corn and bacteria” is wrong. Bacteria can be decomposers, producers (cyanobacteria), or consumers.
• Consumers are organisms that eat other organisms. Mice eat plants (corn) and insects eat parts of plants or other small organisms. So “consumers - mice and insects” is correct.
• Decomposers break down dead plants and animals. Hawks are consumers (top - level predators), so “decomposers - hawks and bacteria” is wrong. Bacteria can be decomposers, but hawks are not.

Answer:

1. consumers – mice and insects
