Answer:
Because volvox can photosynthesise
Explanation:
Volvox is a multicellular algae. They grow in spherical colonies.
Its cells contain chloroplasts meaning it can photosynthesise. This means it can use light energy from the sun to synthesise its own food. Therefore, it doesn't need to capture food from the environment.
The ductus arteriosus allows fetal blood to move from the pulmonary trunk into the aorta. The ductus venosus on the other hand is a fetal vessel that transports blood from the umbilical vein to the inferior venacava. Ductus arteriosus is a blood vessel connecting the main pulmonary artery to the proximal descending aorta. It allows most of the blood from the right ventricle to bypass the fetus's fluid-filled non-functioning lungs.
The different sizes of animals are related to the amount of food available in these environments.
<h3>How does altitude influence species richness?</h3>
The study in mountains with increasing altitude and increased species richness at heights of evidenced, followed by a reduction in richness with increasing altitude.
With this information, we can conclude that the different size of the lizards is explained by the amount of food available in the place where it is inserted.
