What traits make archeabacteria likely relatives of Earths earliest organisms?
Archaea share similarities with early organisms in their ability to thrive in extreme environments, their simple cellular structure, and their reliance on sources of energy that were likely available on early Earth, such as hydrogen, sulfur, and methane. They also lack the complex membrane structures found in eukaryotic cells, resembling the simpler cells that are thought to have originated early in Earth's history.
Does photosynthesis deposit energy in earths saving account for living organisms?
Yes, photosynthesis is the process by which plants convert sunlight into chemical energy in the form of glucose. This energy is stored in plant tissues and is used by other organisms when they consume plants, making photosynthesis a key component in the energy flow of ecosystems.
What are Single celled organisms with rigid silica cell walls in many different shapes?
Diatoms are single-celled organisms with rigid silica cell walls that come in a wide variety of shapes and sizes. They are aquatic microorganisms that play a significant role in marine and freshwater ecosystems. Diatoms are known for their intricate and beautiful glass-like cell walls.
What substances is not able to preserve entire organisms?
there are a lot of substances that wont preserve an organism. one would be molten rock under the earths crust or feathers something that cant keep it compact and still in one piece over millions of years.
Which process in living things evolved as oxygen levels increased in earths atmosphere?
Aerobic respiration evolved as oxygen levels increased in Earth's atmosphere. This process allows living organisms to efficiently extract energy from food by using oxygen to break down glucose molecules and produce ATP. As oxygen became more abundant, organisms that could perform aerobic respiration gained a significant evolutionary advantage.
According to its name the archaeozoic era of earths history was characterized by what type of life form?
unicellular organisms are earliest forms of life

What is Earths biosphere is?
living organisms - study island answer (:
What is earths oldest form of life?
Single cell organisms date back to approximately 3.5-3.8 billion years old. These are bacteria and archaea.
How is hypothesis about earths earliest life forms consistent with fossil evidence?
I know you have a textbook so use it
What percentage of earths water is fresh water available for use by living organisms?
three percent of all the earths water is fresh water
How much do humans currently consume of the available food crops and medicine produced by earths organisms causeing a potential threat to biodiversity?
Humans currently consume a great amount of the available food crops and medicine produced by earths organisms. This is a threat because some of these organisms are rare.
Which two factors define the earths biomes?
each biome has a certain climate and organisms
How did earths early organisms obtain food?
That organisms have many lifes substances that could involved how many they will actually have in common in scintifice will hav more.
Why pieces of earth's earliest crust do not exist today?
Earth's earliest crust, which formed over 4 billion years ago, has been recycled through processes like subduction, where it is pulled back into the mantle. This constant recycling of Earth's crust, along with the effects of erosion and weathering, means that no original pieces of the earliest crust remain intact today.
What are the effects of living organisms on the earths surface?
Biggest effect is oxygen. Minor effects is a temperature regulation by modulation of CO2.
Which major biome type contains most Earths biodiversity?
Forests contain about 70% of the biomass, the total weight of living organisms.
