A temperate deciduous forest is dominated by oak trees, which produce acorns. Populations of deer, black bear, and squirrels all rely on the acorns as a primary source of food. A large portion of the forest is cut down, causing it to lose most of its oak trees. What is most likely to happen in the forest as a result?

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.
