Which of the following is the main source of energy for living things?
All lifeforms need energy to survive. Energy is the resource that allows organisms to do things. What kinds of things might an organism do with energy? The answer to this question is as varied as the lifeforms that use energy. Some, like the African Lion, use energy to chase after prey. Other lifeforms, like many creatures we find in the depths of the Earth's oceans, use energy to create their own light. Living things use energy to grow, to defend themselves, and to move around
The first organisms on earth were most likely todays?
The first organisms on life were supposedly (scientifically) single cell organisms. We have a couple hundred billion lying around modern day.Some of Earth's first organisms were similar to today's bacteria.
What kinds of organisms survived the mass extinction that killed the dinosaursWhat kinds of organisms survived the mass extinction that killed the dinosaursWhat kinds of organisms survived the mass ex?
Cretaceous-Paleogene extinction event was one of the most important events in Earth history. When a massive asteroid fell on the coast of Yucatan in modern Mexico it eradicated about half of all animal species, including the dinosaurs. But many of other organisms, such birds, survived. Also survived many organisms with light mass: early mammals, insects, some reptiles, etc.
What was hutton's contribution to evolution?
James Hutton is often regarded as the father of modern geology, and his contributions laid the groundwork for evolutionary theory. He proposed the concept of deep time, suggesting that the Earth is much older than previously thought, allowing for gradual changes in organisms over long periods. His idea of uniformitarianismβthat the processes shaping the Earth today are the same as those in the pastβimplied that the same slow, continuous processes could lead to significant biological changes over time, influencing later thinkers like Charles Darwin.
What is is similar among all living organisms on Earth?
All living organisms on Earth use DNA as their genetic material.All living organisms use cellular metabolism to obtain and use energy.All living organisms have some form of response to external stimuli.All living organisms undergo reproduction.All living organisms are made up of one or more cells, the basic unit of life.

What were the earliest lifeforms on earth like?
The earliest lifeforms on Earth were likely single-celled organisms, such as bacteria and archaea. These organisms were simple in structure and relied on primitive forms of metabolism to survive. Over time, they evolved into more complex life forms.
What was the era with no lifeforms on Earth?
The Hadean Eon, the earliest time interval, was when the Earth was cooling, and continents and oceans formed. Lifeforms are thought to have appeared in the following eon, the Archean Eon.(eras are a much smaller time interval, and the Hadean is not normally subdivided into these)
What organisms are thought to have been the first to appear on earth?
bacteria
The first eukaryotic organisms on earth were?
The first eukaryotic organisms on earth were likely single-celled organisms such as protists, which are a diverse group of organisms that have a nucleus and other membrane-bound organelles. These organisms are thought to have evolved around 1.6-2.1 billion years ago.
Members of which domain were thought to be some of the first organisms on earth billions of years before dinosaurs?
Archaebacteria
Members of which domain were thought to be some of the first organisms on earth billions of years before the dinosaurs?
Archaebacteria
What is the most primitive life on earth?
The most primitive life on Earth are single-celled organisms such as bacteria and archaea. These organisms have simple cell structures and are thought to have been some of the first life forms to appear on Earth billions of years ago.
Does any planet besides earth have lifeforms on it?
yes on Jupiter scientists found a small molacule
Why do nuclear bombs harmful?
Because the Blast and radiation are considered harmful to all lifeforms on the Earth.
What are considered the oldest multicellular organisms on earth?
One of the oldest multicellular organisms on Earth are believed to be the Ediacaran biota, which lived around 635 to 541 million years ago. Fossils of these ancient organisms show evidence of complex multicellularity, though their exact classification and relationships to modern organisms are still debated among researchers.
What element upon which most modern organisms depend was missing from earth's early atmosphere?
Oxygen was the element missing from Earth's early atmosphere, which eventually accumulated due to early photosynthetic organisms. This change in the atmosphere allowed for the evolution of organisms that rely on oxygen for respiration.
What idea of Darwin's based on fossils and modern organisms he found basically say genetic changes are inherited by later generations?
what term defined as the study of the distributon of organisms on earth
