Past bombardment by asteroids is not a source of Earth's internal heat. The correct sources are mantle convection, radioactive substances, and gravitational contraction. Asteroid impacts are not a constant or ongoing source of internal heat.
The Earth's internal heat is primarily caused by three sources: mantle convection, radioactive substances, and gravitational contraction. However, past bombardment by asteroids is not a source of Earth's internal heat.
Let's briefly define these terms:

Answer:
it is by reducing the need for fossil fuels through the use of biofuel etanoel
Explanation
Photosynthesis does not release carbon back into the atmosphere. Option (d) is correct.
A layer of gases known as the atmosphere envelops the planet Earth. The gravitational pull of the planet's neighbor, Earth, keeps it close to the surface. The three primary elements of the atmosphere are nitrogen, oxygen, and argon.
Naturally, photosynthesis removes carbon dioxide, and trees are particularly adept at storing the carbon that is taken out of the atmosphere via photosynthesis.
The fermentation of lactic acid does not result in the production of carbon dioxide gas. The method doesn't use any oxygen, which is the cause of that. However, carbon dioxide gas is a byproduct of other activities such aerobic respiration and alcoholic fermentation.
Therefore, Option (d) is correct. Photosynthesis is correct answer.
