(b) Increased conduction
(c) Reduced radiation
(d) Increased radiation

Answer 1

Horses sleep under trees to reduce radiation and keep warm.

Step-by-step explanation:

On cold, clear nights, horses sleep under the cover of large trees to help them keep warm by reducing radiation.

When a horse is under a tree, the tree acts as a shield, blocking some of the heat loss through radiation. The tree absorbs the heat and prevents it from escaping into the cold night air, creating a warmer microclimate underneath.

This is an example of how animals use their environment to regulate their body temperature and conserve heat.
