A branch of science, which deals with the natural procedures that comprise fire within an ecosystem and the ecological influences it imparts, the association between the biotic and the abiotic constituents of an ecosystem with the fire, and the role played by fire within an ecosystem is termed as a fire ecology.
Different kinds of ecosystems like savanna, prairie, coniferous forests and chaparral have originated by the contribution of the fire, which plays an essential role in the renewal and vitality of the habitat.

Answer:
D the train
Explanation:
The train is safe very fast and was the first built
ANSWER: None of the above options are correct.
Cardiac Output(CO) = Stroke Volume(SV) × Heart Rate(HR)
Therefore where HR= 90bpm and SV= 110ml/min,
CO = 90 × 110 = 9900ml/min or 9.9L/min.
EXPLANATION:
CARDIAC OUTPUT is the volume of blood being pumped by the heart into the systemic circulation per minute.
Cardiac output is the product of two variables, stroke volume and heart rate.
STROKE VOLUME is the amount of blood pumped out by the left ventricle in each contraction.
HEART RATE is the count of the number of times the heart beats per minute.
