A) characterized by four seasons. Deciduous forests have four seasons because they are located between polar regions and the tropics. Leaves from trees fall off during winter. Annual precipitation is 750 to 1,500 mm per year and is spread evenly throughout the year.

Answer from: mikealonso

Answer is A) characterized by four seasons.

Deciduous forest is characterized by the trees whose leaves fall seasonally. Trees of this forest grow in areas where there are four distinct seasons and having annual rainfall between 750 to 1,500 mm. The fallen leaves from the trees provide a regular source of organic matter to the soil. The trees in deciduous forest is dominated by broad leaf trees such as oaks, maples, beeches. Besides these trees shrubs and perennial herbs also found in abundance.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
