Is called autotroph organisms that create organic molecules needed for survival from inorganic sources. this is achieved through photosynthesis (which is light energy) or chemosynthesis (which is chemical energy).
And photosynthesis is when autotrophs capture and convert the light energy from the sun into usable chemical energy (which is their food).

Answer:
Natural selection
Explanation:
Natural selection occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that it is able to survive and reproduce in a given environment. If an allele reduces fitness, its frequency will tend to drop from one generation to the next.
Answer: Option B
Explanation: The thin layer that forms the outer covering of the cell is known as the cell membrane. It is composed of the lipid bilayer which as embedded proteins.
This membrane is selectively permeable which means it allows only specific molecules to pass through them.
The main function of cell membrane is to protect the cell from the outer environment and by the invasion of harmful bacteria and viruses.
<span>"they form a cyst: a hard covering is formed around the protozoan and metabolic rate is slowed"</span>
