What is organic activity?
1. Changes occurring in living things. 2. Changes, including growth, taking place in complex systems (societies, computer networks, and the like)

What is earths suface and atmosphere?
The Earth's surface and atmosphere are distinct layers of our planet: Earth's Surface: The Earth's surface refers to the outermost layer of the planet, which includes the solid landmasses, bodies of water (oceans, seas, lakes, rivers), and everything that makes up the top layer of the Earth. It is where life as we know it thrives, with various ecosystems and habitats for organisms. The surface features include continents, mountains, valleys, deserts, forests, and more. Earth's Atmosphere: The Earth's atmosphere is the layer of gases that surrounds the planet and is held in place by gravity. It consists of several layers, with the troposphere being the closest to the Earth's surface and the exosphere being the outermost layer. The atmosphere contains gases like nitrogen, oxygen, carbon dioxide, and traces of other gases. It plays a crucial role in regulating the planet's temperature, weather patterns, and protecting it from harmful solar radiation. These two layers, the surface and the atmosphere, interact in various ways, including the exchange of heat, moisture, and gases. Together, they create the conditions necessary for life on Earth and the complex systems that govern our planet's climate and weather.
What were the two effects of rising oxygen levels in the atmosphere?
The Two Effects areA) The Gases from the volcanoes which carried water vapourB)The Water vapour then increased the amount of oxygen.A:1) Killing off early Anaerobic bacterial life 2) Allowed more complex organisms to evolve3) Created the ozone layer which blocks harmful radiation from the Sun
Why did complex organisms that inhabit the earth develop?
"They" happened by accident (i.e. mutations), and the ones that were more efficient eat the less efficient. That's life.
What changes were necessary in earth's atmosphere to allow complex organisms to evolove?
During the few billion years following the appearance of cyanobacteria, oxygen became a major gas in Earth's atmosphere. The ozone layer in the stratosphere also began to develop, shielding Earth from ultraviolet rays. These major changes in the air allowed species of single-celled organisms to evolve into more complex organisms.
What was the significance of the development of chloroplasts?
The development of chloroplasts led to the oxygenation of Earth's atmosphere, which allowed the evolution of more complex oxygen-breathing organisms.

What are advantages of human beings are complex organisms?
advantages of human beings are complex organisms
Why do complex organisms need specialized cell?
Complex organisms need cells that perform many different functions. Complex organisms are capable of a lot of different things, and that variety needs to be supported on the cellular level. Without them, complex organisms cannot perform different functions.
What is the name for a complex organisms groups of organisms?
System
Why are complex organisms made up of specialized cells?
Complex organisms need cells that perform many different functions. Complex organisms are capable of a lot of different things, and that variety needs to be supported on the cellular level. Without them, complex organisms cannot perform different functions.
Will advanced organisms be the same as complex organismswhy?
The complexity of body design will increase over evolutionary time. This is the process by which new modifications occur in the organisms. So, in this way we can say that advanced organisms will be complex as compared to complex organisms...
What events occurred that allowed single - celled organisms to into more complex organisms at the end of the precambrian time?
the ozone layer began to develop shielding earth from ultraviolet rays, this was hypothesized that these changes allowed species of single celled organisms to evolve into more complexed organisms
Which evolved first - organisms with complex body structures or those with simple body structures?
Complex organisms evolved from simple organisms, so simple organisms evolved first.
