Answer:
The tilt of earth's rotation axis stays the same as it orbits the sun.
Explanation:
The axis of the Earth is an imaginary line around which the Earth is known to orbit. The axis of the earth is known to tilt at an angle of 66 and a half degrees. The tilt of the axis of the Earth remains the same and it does nor change as the earth orbits around the sun. The orbiting of the Earth around its axis causes day and night to occur on the planet Earth. The rotation of the Earth around its axis is slowing with time.

Answer:
This question lacks options, options are:a.Eating and breaking apart food converts carbon to other elements.b.Eating and breaking apart food converts other elements into carbon.c.Eating food involves taking up carbon dioxide.d.Eating and breaking apart food releases carbon dioxide as a byproduct.The correct answer is d.
Explanation:
Heterotrophs are organisms unable to photosynthesize, so they obtain energy and carbon through the consumption of other organisms.Carbon enters all the trophic networks through the autotrophs, these create their own food by fixing carbon, that is, they capture the carbon dioxide that forms the air or dissolved in water and use it to produce organic compounds. Heterotrophs, which feed on other beings (obtain their food from organic sources present in their environment), consume organic molecules and thus organic carbon passes through the chains and trophic networks. Carbon atoms through respiration in the form of carbon dioxide are released.
