Question

question 1 (1 point) soil ph is a measure of acid - content in the soil. the graph below shows the tolerance of earthworms to ph. in a meadow where earthworms live in the soil, the ph gradually decreases from the optimum range into the zone of stress. what is the most likely effect on the earthworm population? tolerance lower limit of tolerance zone of stress optimum range zone of stress upper limit of tolerance population low ← range of soil ph → high a earthworms will produce fewer offspring, but more of those offspring will survive. b earthworms will produce more offspring, and more of those offspring will survive. c earthworms will produce fewer offspring, and fewer of those offspring will survive. d earthworms will produce more offspring, but fewer of those offspring will survive.

Explanation:

When the soil pH moves from the optimum range into the zone of stress for earthworms, it becomes a less - favorable environment. In stressful conditions, organisms generally have reduced reproductive output and lower survival rates of offspring due to the physiological stress caused by the sub - optimal environmental factor (in this case, soil pH).

Answer:

C. Earthworms will produce fewer offspring, and fewer of those offspring will survive.
