im studying for my upcoming test and these are some sample questions my teacher posted, i need help with most of the questions and help for any of them is appreciated , i need to know the reason why they are either true/false too.
please help
Answer True or False
2a) The fundamental niche will always be larger than the realized niche in herbivores that are frequently attacked by predators.
2b) Rare individuals perform best under negative frequency dependent selection.
2c) Sex role reversals should be most common where sons are cheaper to produce and easier to rear
than daughters.
2d) Honest signals should be most often associated with high costs of production.
2e) Competitive exclusion is an extreme form of niche reduction. ____________________________________
2f) Sexual selection is a special form of natural selection that deals sexual reproduction i.e. selection to produce sexually to increase genetic variance.
2g) The higher the variance in quality among egglaying sites, the more pronounced the fighting characters in male salmon.
2h) In bamboo, plants that reproduce out of synch with the other members of the population will accrue high reproductive fitness.
2i) Ecosystems are defined by the unique biological communities that they harbor.
2j) Trait mediated effects can cause change in realized replacement rates.
2k) Replacement rate values of 1.0 are impossible to achieve when death rates exceed 0.5.
2l) Habitat fragmentation leads to decoupling of population dynamics among sub-populations.
2m) Inbreeding depression is most commonly observed in human females who suffer from morning
