A cousin who has been traveling overseas sneaks a plant through customs (who help along with the USDA, help to prevent invasive species) wants to plant this plant in their backyard. What would you say to them to discourage them from doing so? Please facts and scientific reasoning to convince them not to and to destroy the plant.

Answer and Explanation:

Invasive species are not native to an ecosystem/environment to which they've been introduced, which can cause disastrous disruptions to various food chains/webs and other native species' populations.

In this case, your cousin is bringing in a plant from overseas, so it clearly will be an invasive plant. You can tell them the following:

- this plant may take over the feeding source of native plants, causing those populations to decrease drastically or possibly even be wiped out

- secondary consumers that had once relied on those native plants for food energy will now have limited resources, competition will increase, and these consumers may begin to die off

- tertiary consumers that consumed these secondary consumers will begin to die off, as well

- this chain reaction will ripple through the entire food chain and food web, and totally disrupt the existing ecosystem

Thus, your cousin shouldn't plant this organism in their backyard and should instead destroy it.

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.
