Trees can benefit fauna. The most common examples are silvopasture where cattle, goats, or sheep browse on grasses grown under trees. In hot climates, the animals are less stressed and put on weight faster when grazing in a cooler, shaded environment. The leaves of trees or shrubs can also serve as fodder.
Context:
Two farmers from the same village raised animals. The village was situated in a hot climate. They took the animals to graze on pastures nearby. Tom took his animals to a silvopasture, while Bill took his to a grassland.
Q: Which farmer had fewer animals grazing in a cooler environment?
