Answer: LABORATORY EXPERIMENTS
Explanation:
Exponential growth can be define as the increase in per capita growth of the population when the resources available are surplus. A limiting factor is the one which is capable of limiting the growth, abundance and distribution of population of species. Predator populations, habitat conditions and food resources all are examples of limiting factors which can limit the growth of population exponentially.
Laboratory experiments cannot be consider as limiting factor hence, are not responsible for limiting the exponential growth.
B. are more difficult to control than point sources. This is because A. is wrong (point source), and C. is wrong, because it doesn't necessarily cost less or more to identify the sources. D. may be right, as non point sources are natural, such as snow melts or rain.
I think it is A if not it is B
Here is your answer:
Fungi are different from plants because "they do not need sunlight to grow" most fungi could grow in harsh conditions and do not need sunlight to grow. Some grow deep in caves where there's no sunlight at all but still grow. Plant's need sunlight they cannot grow without it. Some fungi can even form and grow on humans, but plants can't.
Hope this helps!
