Algae need nutrients like carbon, nitrogen, and phosphorus, among others, in order to grow. could carbon ever limit algae growth?
no. carbon is abundant everywhere and so it can never be a limiting nutrient for algae
no. algae are too small to ever require more carbon than what is available in the environment
yes. because carbon is needed by algae to grow, it has the potential to limit growth.
yes. whenever phosphorus is added to a lake, algae grow and therefore use more carbon as well.

Look at the data above. provide an explanation for europe’s projected population decrease by the year 2050. (i'm doing this for future kids) the answer is : the percentage of people over the age of 65 and under the age of 15 in europe is currently the same at 16% each. therefore, the majority of the population is between the ages of 16 and 64. in forty years from now, in 2050, a greater percentage of the population will be over the age of 65. europe also has a relatively long life expectancy of 75 years. this, combined with a low birth rate means that by 2050 europe’s population will actually be less than it is today.
