Answer:
A food chain is a representation of what eats what in an ecosystem.
A combination of food chains is termed as a food web.
Example of two food chains in a food web are :
Example No 1:
Plant----- Grasshopper------ Frog---snake--- bacteria
Example No 2:
Plant---- rabbits---- fox---- bacteria
In a food chain, producers are usually plants and algae which are able to make their own food. Consumers feed on the plants. In example no 1, grasshoppers are primary consumers, frogs are secondary consumers, snakes are tertiary consumers.
In example no 2,plants are producers, rabbits are primary consumers and foxed are secondary consumers.
Decomposers are organisms that feed on the dead organisms in a food chain. In both the examples of food chain, bacteria are the decomposers.

Answer:
Pleiotropy
Explanation:
Pleiotropy is a condition that occurs when one gene affect several other phenotypic traits that are not related. The autosomal dominant allele of the genetic disease called blue sclera, is pleiotropic. It has the potential of causing also fragile bones and deafness which are entirely unrelated traits. Genetic mutation of a gene is the most likely explainable reason for the connection of these traits together.
