What are the two sources of energy the fuel life on earth And explain how they do so?
No
Describe the two sources of energy that fuel life on earth?
The two sources of energy that fuel life on Earth are sunlight and chemical energy. Sunlight is converted into chemical energy through photosynthesis by plants and other organisms, creating food that sustains life. Chemical energy is derived from the breakdown of organic molecules through processes like cellular respiration, providing organisms with the energy needed to carry out their functions.
What are the two sources of energy that fuel on life?
sun and the atmosphere The sun and volcanic vents
What sources of energy were available on the early earth?
On early Earth, sources of energy included solar energy from the sun, geothermal energy from the planet's interior, and chemical energy from reactions between different elements and compounds. These energy sources contributed to the emergence of life and the development of early organisms.
What are the 2 sources of energy for all life on earth?
Sun and Food ( that includes water)
How did the three sources of heat prevent life from existing when the earth was formed?
the first sources of heat was asteroids and meteorites. another sources of heat for the early earth was the contraction of gravity. the third sources of energy for the early earth was radioactivity. hope this helped :)
What providers the earth with all energy?
The sun is the primary source of energy for the Earth, providing sunlight that powers photosynthesis in plants, which in turn fuels most life on the planet. Other sources of energy on Earth include geothermal energy, tidal energy, and the Earth's internal heat.
Energy can enter the earth system from internal sources through convection and from external sources through what?
External sources of energy entering the Earth system include solar radiation and cosmic rays. Solar radiation, the primary external energy source, drives various processes and is essential for sustaining life on Earth. Cosmic rays, though less significant than solar radiation, also contribute to the energy balance of the planet.
Energy that fuels life comes mostly from the?
Sun. Plants use sunlight to photosynthesize, converting it into chemical energy that sustains life on Earth. Other sources of energy, such as geothermal and chemical energy, also play a role in fueling life processes.
What forms of energy are vital for life on earth?
The key forms of energy vital for life on Earth are solar energy, which powers photosynthesis in plants to produce food, and chemical energy, stored in the bonds of molecules like glucose for fuel. Both of these forms of energy are used by organisms to carry out their life processes and sustain growth and reproduction.
What are the source of life in earth?
The primary sources of life on Earth are water, energy from the sun, and organic molecules such as carbon-based compounds. These elements provide the necessary building blocks and environment for life to exist and thrive.
What is the definition of obtaining energy?
Obtaining energy refers to the process of acquiring or harnessing energy from various sources, such as food, sunlight, or fuel, to power the activities and functions of living organisms or machines. It involves converting the stored energy in these sources into a form that can be used to perform work or sustain life processes.
