a chemical reaction plants use to create food
True I’m pretty sure! Hope I helped
Easy:
The four chambers of the heart are the right and left atria, and the right and left ventricles. The main veins connected the heart are the superior and inferior vena cava, the main artery is the Aorta.
The first chamber, (the right atruim) recieves deoxygenated blood and forces it into the right ventricles which forces the blood into the lungs for oxygenation. Then the blood reenters the heart in the left atrium, which forces the blood into the left ventricle and then out the Aorta to the rest of the body.
sorry, but this question needed kind of a long answer to be answered correctly.
Ans. (A).one species would be force to leave.
A niche is defined as a specific area, where an organism lives and interacts with all the abiotic and biotic factors that affect it.
Two organisms cannot survive in the exactly same habitat as they will compete for same resources, so one will die). Hence, one of the two competing species gets evolved to use a different niche and uses different sources. This is known as resources partitioning and helps the organisms to coexist by reducing competition between them.
Thus, the correct answer is option (A).
