<span>An
atom with an atomic number of 12 has 12 protons. Because the mass
number is the sum of the protons and neutrons, the mass number would
need to be at least 12. I hope this helped!

1)Biotic factors are the living components of an ecosystem. These include living animals, plants, and microscopic organisms like bacteria.
Abiotic factors are the non-living components of an ecosystem. ... Biotic and abiotic factors both influence each other.
Answer:
unicellular; multicellular
Explanation:
<em>The smallest and the most basic unit of life is the cell. Living organisms that are made of just one cell are said to be </em><em>unicellular </em><em>while those that are made up of multiple cells are said to be </em><em>multicellular.</em><em> Many unicellular organisms are some of the smallest living organisms to exist in nature. They cannot be seen with the ordinary eyes, except with the aid of microscopes.</em>
Answer:
2 unit
Explanation:
According to the 10% law, the transfer of biomass energy from one higher trophic level to lower trophic level is only 10%.
Primary(Producer)→Primary consumers→secondary consumers→tertiary consumers.
that is 2000→200→20→2
note: only 10% of the total biomass is received by the next trophic level.
therefore tertiary consumers will receive 2 units of biomass.
