In the autumn, many birds will collect seeds and then hide them in various caches throughout their habitat. The birds will guard
their caches from other birds, and move the caches if they start to dry out. These caches provide a food source for the birds during the winter. What is an abiotic factor that contributed to the evolution of this set of behaviors? A. cold winter climate
Abiotic factors refers to the physical and climatic conditions of the system. The observed behaviour to collect the seeds and hide them has been evolved in response to unfavorable conditions during winter season. The given birds prepare themselves to survive the harsh climatic conditions and low food availability during winter by storing the seeds during autumn.
Both biotic and abiotic factors are responsible for shaping the evolutionary framework of the population. Resource availability can be one of the important abiotic factor in determining the evolutionary dynamics of the population or species. Limitations in resource can result in increase in competition. According to population exclusion principle when two species compete for the same limiting resource this results in co-evolution of both the species. But the extent of evolution may vary among the species. The one which undergoes more favorable evolution will be stronger competitor and drive more resources and will be fit for survival in adverse limiting conditions.
Since the genes are located in the nucleus of a cell which has being removed (but some genes are still located in the mitochondria of the ocyte) from its ocyte to fuse it with with another nucleus. Since the cell follows a maternal inheritance of gene, it would have a small head because of the presence genes in the mitochondria.
