Answer :There was enough oxygen in the atmosphere to support a major burst of life on Earth
Explanation:
The Great Oxygen Event marks the time, approximately 2.5 billion years ago, when there was enough oxygen in the atmosphere to support a major burst of life on Earth
For the first half of the Earht's history, there was no oxygen in the atmosphere. It was inhabited only by single-celled organisms.Of those simple life forms, the cyanobacteria may have. evolved a way to take energy from sunlight, and used it to make sugars out of water and carbon dioxide. They used the same chemical process we know as photosynthesis. This released vast quantities of oxygen into the atmosphere and triggered the evolution of complex life.
The right answer is b. Tree.
Some plants (like trees) have evolved with different unusual nutritional adaptations over time. Heterotrophic plants are plants that use only or partly a source of organic carbon to grow, unlike the most common autotrophic plants, which use inorganic carbon and water to grow, often through the process of photosynthesis (photoautotrophic).
