  • A main difference between the two is how they forage. 
  • Sheep are grazers; they ramble slowly eating short plants close to the ground.
  •  Goats are browsers;
  •  they look for leaves, twigs, vines, and shrubs. And their agility allows them to attain charming positions in pursuit of their forage. 
  • They will defend their pride's territory, which can cover up to 100 square miles.
  •  Females are primarily responsible for hunting, which typically occurs after dark.
  •  They are also the primary caregivers for lion cubs.
  • Both male and female lions hunt
  • The reason females hunt more frequently, is because the male must spend more time defending his territory. Another reason is that males are more conspicuous in the bush with their dark colored manes, while females are more camouflaged and therefore less likely to be detected.
  • EVERYTHING HAS ITS OWN WAY OF LIVING AND EXISTING.
