What are two ways nonliving things could affect
yellow-rumped warblers?

the nonliving things that could affect  yellow-rumped warblers is the temperature and humidity of the atmosphere.

Explanation:

Yellow-rumped warblers is a type of bird which is found in central and North  America. Temperature and humidity has a great impact on yellow-rumped warblers. They migrate to central america when the winter season arrived because the climate of central and north america is warm and wet due to more rainfall. This bird does not tolerate the extreme low and high temperature so that's why they migrate to warm areas in the winter.

it would lead to upper respiratory infections and pneumonia.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
