Ans 1. Both
Ans 2. Once inside plants, carbon moves through food chains, where organisms become nutrients including herbivores, carnivores and ultimately, decomposers. Once buried in the soil, carbon can be converted into fossil fuels over long periods of time and then also reenter the atmosphere by combustion. The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law
Ans 3. Most of the chemical energy needed for life is stored in organic compounds as bonds between carbon atoms and other atoms. The law of conservation of energy states that energy can not be created or destroyed. Thus, just like matter energy is also conserved in the process.
Hope it helps
C. An ionic bond is a bond between charged atoms while a covalent bond is a bond between opposite charges
Average atomic mass is =1.11 u
need brainliest
Body elements and trace fossils I believe
Mass number is the sum of protons and neutrons inside an atom.
Atomic mass = no. of protons + no. of neutrons
