Savanna Ecosystem Characteristics
The observation that savannas are characterized by seasonal droughts and fires that influence their plant and animal life best supports which of the following conclusions?
A
Savannas are unaffected by seasonal variations, with constant rainfall and absence of fires leading to uniform vegetation.
B
Savannas experience continuous heavy rainfall, preventing fires and promoting the growth of dense forests rather than grasslands.
C
Savannas are primarily aquatic ecosystems, where droughts and fires have no impact on the predominantly water-based plant and animal life.
D
Savannas are dynamic ecosystems where periodic droughts and fires play a key role in maintaining biodiversity and ecosystem structure.
