The given statement is false.
The fires are essential to both the grassland and savanna ecosystems. The grasslands and savannas are featured by two seasons, which are sustained by fire, and exhibit species that are impervious to drought. These fires help in following on the sequences and permit for habitats to maintain their resolution.
The African savanna ecosystem refers to a tropical grassland with warm temperatures over a year, and with its highest seasonal rainfall in the summers.
Answer:
h - height
Explanation:
gravitational potential energy = m * g * h
m stands for mass. Mass doesn't change in physics
g stands for gravitational acceleration. It is a constant.
h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.
