Which of the following statements are true about the impact of competition and environmental filtering on community structure. A
torisob [31]

:

D. Both competition and environmental filtering shape community structure.

Explanation:

Based on competition theory,  two  organisms occupying the same ecological niche can only coexist   provided  there is spatial or conditioning niche partitioning.This  prevent  competitive exclusion , ensuring survival of the two species in their niche. Since the two species developed greater variability in (over-dispersed traits)  to resist the selection  pressure,(competition).Many overdisperesed traits is present in the communities.

  However environmental filtering, is concerned with selection of species with  natural ability or triats to survive in a given communities,Thus if two species of organism  meet the same ecologocal requirements in a community, environmental filtering, fitters them and ensure their survival ahead of others who do not meet the requirements, and could not survive.

Thus the simultaneous operation of theses  two opposing selection pressures, structured communities ensuring coexistence and favoured ability of organism to survive.

13) Crossing over is important because it creates ___.
Ainat [17]

Crossing over is important because it creates genetic variability.

<h3>What is crossing over?</h3>

It is the exchange of chromosomal segments between non-homologous chromosomes in a tetrad.

Since chromosomal segments contain genes at different loci, the exchange will increase the genetic variability of the new chromosomes.

Thus, the daughter cells carrying the recombined chromosomes will be genetically variable from not just the parent cell, but fellow daughter cells.
