Answer is D: the current make up of the crust
Changes in the temperature of the Earth's core will do the following:
1. Cause the outer core to solidify
-this means that the liquid outer core which is responsible for generating the magnetic field protecting us humans from solar radiation will be gone
2. Cause the mantle to solidify
-this means that if the mantle solidifies, the plate tectonics will stop moving around, and if this happens, the earthquakes and volcanoes will not be produced anymore and also mountain ranges will not be renewed, and the earth will be flattened by erosion.
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.
