Question 1 · Single choice — select one

A researcher finds that changes in soil management affect microbial communities in soil, plants, and animals, which may influence food quality and human exposure to microorganisms. Which interpretation best reflects a One Health perspective?

The main concern is agricultural productivity because soil microorganisms primarily influence plant growth. The main concern is human health because microorganisms are relevant mainly through disease pathways. The findings demonstrate that soil, plants, animals, and humans are connected through biological and environmental pathways that influence health across systems. The findings are primarily relevant for ecosystem science because soil organisms regulate ecological processes.

Question 2 · Single choice — select one

A city converts several biodiverse green spaces into highly sealed urban surfaces. According to the biodiversity hypothesis discussed in this lesson, what could be one possible consequence?

Increased exposure to environmental microorganisms may strengthen immune responses. Reduced contact with diverse environmental microorganisms may affect immune system regulation. Human gut microbiomes become completely independent from environmental influences. Allergies and asthma are eliminated because fewer microorganisms are present.

Question 3 · Multiple choice — select all that apply

Soils in a farming region have low concentrations of a specific micronutrient required by humans. Which outcome is most consistent with the relationships described in this lesson? (select all that apply)

Human nutrient intake is not related to soil conditions. Plants compensate automatically for all soil nutrient deficiencies. Soil nutrient content influences crop yield but not crop nutritional quality. Crops grown on these soils may contain lower concentrations of the nutrient, potentially affecting human nutrition.
