An organism that can make its own food is called an "Auto-troph". They maybe of two types:
1) Photo-Autotroph (Get source by sunlight)
2) Chemo-Autotroph (Get source by chemicals i.e., CH₄, NH₃ etc.)
Hope this helps!
Primary producers are mostly plants. Primary producers will probably experience some downfall due to the large number of fish. And if the producer species becomes extinct, then that could mean disaster for the entire community. I hope this was helpful in some way!

Answer:
The correct answer to the question: For this individual, select the pair of recombinant genotypes that could result if crossing over occurs between these two chromosomes, would be, 3. Ab and aB.
Explanation:
During meiosis, the copy and distribution of genetic information present in genes, and which happens when chromosomes are divided and then crossed over, is a pretty unique one.
Essentially, genetic recombination happens when genes cross over and combine with genes present close to them. This process does not always happen and it is the reason why we say that some gametes are parental, instead of recombinant; because the genes in the chromosomes, especially depending on factors like distance between them, do not combine.
In this particular case, given the way that genes will cross over and knowing how recombination works, we could say that the possible genotypical recombinants for AB on chromosome 1 and ab on chromosome 2 would be the ones offered in option 3.
The enzyme pectinase speeds up the breakdown of pectin in fruits, producing more juice. It speeds up breakdown of pectin in plant cell walls, thus creating more juice. It is also used in wine making to avoid cloudiness
