Approximately 10% of energy is lost at each step of the food chain. Therefore larger predators must eat more to gain their energy requirements. For example if a Fox was third on the food chain it would only receive 1% of the energy the producer made
Persistent chlorinated hydrocarbon pesticides persist in the environment and accumulate in the foods chain causing harmful effects on the environment including posing a threat to humans health in the long term. Nonpersistent organophosphate pesticides are more toxic than the former but degrade after a short life span. Therefore they cause immediate harm in case one is in contact with them.
The fact that they do not accumulate in the environment, they are more favourable than chlorinated hydrocarbon pesticides. Chlorinated hydrocarbon pesticides will affect several generations due to their accumulation in the environment. However they don't need to be re-applied hence are less expensive
They are similar to those of primary succession, primary succession occurs in an area without any initial. Succession always begins on a barren surface, whereas secondary succession be gains in environments that already possess soil. I hope this helps.
in mendelian genetic , allele of each genes from the parents will segregate from each other so the gametes only carry one each.
If the parental mice has two different fur color (i.e white and Black) , the color of the offspring's fur would be either black, white, or the combination of both (Grey)
hope it helps
