In every ecosystem, there are different organisms that interact with each other in a particular environment.
The components of an ecosystem interact and interrelate with the ones that form part of another. Every ecosystem is related to another one.
For example, in a food chain, a bird eats a fish, both animals belong to different ecosystems, but they are connected with each other.

Dna replication needs to occurs because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. so the dna needs to be copied before cell division so that each new cell receives full set of instructions. - Google
A chain of amino acids folded and twisted into a molecule
Answer:
The correct answer is C. The tertiary structure of a polypeptide is the overall three-dimensional shape of a fully folded polypeptide.
Explanation:
A polypeptide is a molecular chain composed of at least 10 amino acids (which are the molecules that make up proteins). When we talk about its tertiary structure, it refers to the complete overall three-dimensional structure of the polypeptide units of a given protein, where the polypeptide chain is fully folded and compacted. This folding is facilitated by unions called disulfide bonds, which are created from the cysteine residues, these bonds (called disulfide bridges as well) help to stabilize many polypeptides.
