What else can I help you with?
When no animal and trees then how you will live on earth?
You wont... trees provide oxygen so we can breathe ( plants included) and animals -for some, provide food.
What four human needs that will have an impact on Earth?
in any embryonic development, an embryo must have protection from the environment, a food source, a place for waste, and a source of oxygen
What conditions are necessary for life on Earth?
damien because he is a stupid American
What food do you eat on earth day?
Food you usually eat.
Can humans only live on earth?
No, it is not for only humans. It existed long before humans appeared and will exist long after we are gone; in that time, it has, is and will support hundreds of millions of other types of organism.
What does the atmosphere surrounding earth provide oxygen for?
The atmosphere surrounding Earth provides oxygen for living organisms to breathe and carry out cellular respiration, which is the process that releases energy from food. This oxygen is essential for sustaining life on Earth.
How did early photosynthesis organisms change Earth's atmosphere?
Photosynthetic bacteria produced oxygen, and as they continued to colonize the earth they produced more oxygen. Eventually all the oxygen sinks became saturated, and this resulted in the Great Oxygenation Event (GOE). Aerobic organisms would late evolve and utilize the free oxygen.
Which process producer most of the oxygen in earth's atmosphere?
The process that produces most of the oxygen in Earths atmosphere is photosynthesis. Plants use this process to create food.
Which gases in the earth's atmosphere are essential for life?
Oxygen and carbon dioxide are two essential gases in Earth's atmosphere for supporting life. Oxygen is needed for respiration by most organisms, while carbon dioxide is utilized by plants for photosynthesis to produce oxygen and food.
Why do scientists think that oxygen accumulated in the earth's atmosphere?
Scientists believe that oxygen accumulated in Earth's atmosphere due to the activities of primitive photosynthetic organisms like cyanobacteria, which released oxygen as a byproduct of photosynthesis. Over time, this oxygen built up in the atmosphere through processes like the Great Oxygenation Event, ultimately leading to the oxygen-rich atmosphere we have today.
The abundance of oxygen in Earth's atmosphere is partly because of what?
The abundance of oxygen in Earth's atmosphere is primarily due to photosynthesis, a process carried out by plants and algae that produces oxygen as a byproduct. Without photosynthesis, oxygen levels in the atmosphere would decrease over time due to various processes that consume oxygen.
Can identify the food sources of oxygen element?
Practically all foods contain oxygen; and the first is of course water. Also the Earth atmosphere contain approx. 20 % oxygen as a gas.
How did Earth's atmosphere get oxygen during the Precambrian time?
Cyanobacteria uses sunlight to make their own food. This process releases oxygen. Overtime, oxygen built upon the ocean and air.
What essentials for life are found in earths atmosphere?
The Earth's atmosphere contains oxygen, which is essential for respiration in most living organisms. It also contains carbon dioxide, which plants use for photosynthesis to produce food. Water vapor in the atmosphere is essential for the water cycle, which is vital for all forms of life on Earth.
Why are phytoplankton critical to life earth?
They produce much of the oxygen in the earth's atmosphere that aerobic life requires, and they are at the base of the food chain in most marine environments
Why is there oxygen in Earth's atmosphere?
The oxygen is the product of photosynthesis. Plants and algae use the energy of sunlight to turn water and carbon dioxide into sugar and oxygen. The plants use the sugar as food and turn some into cellulose to make cell walls. Oxygen is released into the atmosphere as a byproduct.
