Here's the simplest and most easy difference to notice:

A food web is made of many smaller food chains.

A food chain is only one set of prey to predators, while a web is a collection with relationships between many sets.

What is recombination and how does it work? is it the same thing as crossing-over? if an organism practiced self-fertilization,
Sever21 [200]
Recombination is the method by which organisms can randomly assort their genotypes amongst each other to create offspring with a different haplotype than either of its parents. This can be done by either copying sequences from one homologous chromosome to another (no physical exchange) or crossing over (physical exchange. 
Crossing over is a mechanism in eukaryotes by which recombination can occur, in which the two homologous chromosomes contributed by both parents literally cross over and break at certain points to exchange certain sections of the chromosomes amongst each together.
Self fertilizing organisms typically do not produce offspring that are genetically identical. However, this has an inbreeding effect on its offspring, since it is recombining from the same genotype and so has a higher chance of producing homozygous offspring. This is very detrimental for mammals and some eukaryotes, but in some other organisms such as bacteria, homozygosity is typically not an issue.

pychu [463]
This is absolutely false.
There is a wide diversity of life teaming around hydrothermal vents. These communities include primary producer organisms, but instead of obtaining energy from the sun, these bacteria use a process called chemosynthesis to convert minerals and other chemicals in the water into energy. These bacteria support a wide range of other animal species, including giant tube worms, deep sea mussels, serpulid or “feather duster” worms, and vent crabs, the apex predator of the vent community.
