Explanation:

The majority of the energy collected by the earth in a day is re-emitted, and the majority of this outgoing radiation is infrared.

infrared rays

Explanation:

Infrared A radiation (IR-A) accounts for almost a third of total solar radiation.

Infrared radiation is a part of the spectrum of electromagnetic radiation that continues to the red part of the visible spectrum.

Most of the absorbed energy of the Sun's radiation is converted by the Earth into heat. The surface of the Earth thus heated emits its electromagnetic radiation back into the atmosphere, in the infrared region of the spectrum (long-wave radiation).

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
