Complete the following statements to accurately describe examples of organisms affecting the Earth’s atmosphere, and subsequent effects on other living organisms.

Starting around 2.7 billion years ago, photosynthesis by cyanobacteria, and later plants, pumped( Carbon dioxide, methane, O2) into the atmosphere. This caused the decline of anaerobic bacteria and allowed the rise and diversification of animals as seen in the (Cambrian, Carboniferous, Cretaceous) event around 500 million years ago.

Early vascular plants ( Captured, Released ) CO2 starting before the (Cambrian, Carboniferous, Cretaceous ) period that began around 350 million years ago, leading to lower temperatures and allowing the seed plants to outcompete seedless plants.

Modern human activity has raised (carbon dioxide, methane, oxygen) levels in the atmosphere to over(20%, 40%, 200ppm, 400ppm)., leading to higher temperatures, and contributing to extinctions of other specie
