Final answer:
Savannas are hot, tropical grasslands with scattered trees. They have a dry season, and the dominant vegetation is mostly grasses and forbs, with few trees. Plants in savannas have developed well-developed root systems that help them recover quickly after a fire.
Step-by-step explanation:
Savannas are grasslands with scattered trees, located in Africa, South America, and northern Australia. They have hot, tropical climates with an extensive dry season. The dominant vegetation in savannas is grasses and forbs (herbaceous flowering plants), with relatively few trees due to fire disturbances. The plants in savannas have well-developed root systems that allow them to quickly re-sprout after a fire.
