A specific nutrient is need for every organism in the ecosystem. If this particular nutrient is diminished within the ecosystem then cellular processes will decreases and a great number of specie will die. </span>
The correct answer is secondary structure of proteins is formed by the hydrogen bonding between amino acid chains.
Explanation:
The secondary structure of protein is generally stabilized by peptides bond along with hydrogen bonding between hydrogen atom and an electronegative atom such as oxygen.
The secondary structure both alpha helix and beta pleated sheet are stabilized by hydrogen bonding beside the presence of peptide bonds.

Reproductive structures consisting of one or more photosynthetic cells surrounded by fungal hyphae are called Soredia.
Explanation:
Soredia and isidia are produced by lichens as reproductive structures.
Lichen is the symbiotic association of an alga or cyanobacterium with a fungus.
Symbiosis is a close association between organism in which both benefit each other.
In lichens the photosynthetic organism prepares food while fungus absorbs nutrients and water.
