Explain how pastoralism and agriculture led to abundant food supplies

I'll attempt to answer this one! Agriculture gave people the chance to grow crops of all kinds depending on their materials or resources. Agriculture was pretty easy for anyone to learn and maintain for themselves. Agriculture led to an abundance because seeds were easy to acquire from the crops to grow more and many people were able to grow their own crops. In terms of pastoralism, people could also raise livestock. They could derive meat from the animals and food sources such as milk from animals like cows or goats. The livestock were pretty easy to maintain as many of them only needed to eat grass to produce/grow well.
