Answer: Plants
Explanation: Less solar radiation would mean less sunlight for photosynthesis which means that they won't get enough energy for survival and might die out.
Answer: The size.
Explanation: On the one hand the Emperor Penguin is bigger reaching up to 48 Inches (120cm) of height and 100 Lb in weight, on the other hand the Galápagos Penguin is much smaller. For example a large adult usually goes up to 21 Inches (53cm) and 5 Lb of weight.
This is directly related to the temperature of the environment in which each one develops, because a body exchanges heat in two dimensions through the surface. So, it's easier for a big creature to maintain core temperature stable.
This is really important in environments like the Arctic where temperature goes below zero and the opposite happen in the Equator where there is a tropical weather all the time.
Answer:
Blue light
Adding 10-20% blue light allowed plants to grow much healthier, with a compact appearance. There is also far-red light which is has wavelengths that are lower than normal red light–similar to near-infrared wavelengths. Far-red light helps the plants produce greater yields.
