in Earth's early conditions?
Answer:
Earth’s primitive atmosphere allowed for more of the Sun’s rays to reach the bacteria. In addition, the oceans and atmosphere were richer in carbon dioxide than they are today. Both of these factors helped green bacteria survive in Earth’s early conditions.
Explanation:
plato
Explanation:
The early atmosphere was mainly made of carbon dioxide and methane.
These early bacteria were able to harness the energy of the sun to make their own food by reducing carbon dioxide into glucose. Due to the abundance of carbon dioxide and sunlight, these organisms were able to thrive, unlike heterotrophs bacteria that depended on other organisms for food.
Photosynthetic bacteria were able to thrive so well that their abundance caused a change in the composition of the atmosphere in what is referred to as the Great Oxygenation Event. They evolved oxygen during photosynthesis hence causing the significant composition of oxygen in the air today.

Gravity is the force that pulls objects toward Earth's center
Objects that have a small mass will have no gravitational pull
Gravitational pull between two objects increases as the mass of one increases
Gravitational puli decreases when the distance between two objects increases
