Answer: i think more animal
Explanation:
Gases in Earth's Atmosphere. Nitrogen and Oxygen are by far the most common. Dry air is composed of about 78% Nitrogen (N2) and about 21% Oxygen (O2). Argon, Carbon Dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases.
So therefore Oxygen is the gas that makes up the largest portion of the Earths Atmosphere.
A molecule.
Have a nice day, hope this helps.

The Savanna or Savannah
The Savanna is a biome that is typically found in Africa and is characterized by a tree density low enough to allow sunlight to reach the ground and allow for smaller plants such as grasses to grow. The growth of these grasses provides an optimal food source for herbivores, which is why large grazing herbivores such as zebras are found here. The presence of these herbivores allows for the existence of larger carnivores such as lions.
