The Jambite team has reviewed how many of you have performed on various subjects and we've found that many people struggled on Question @20. In fact about 85% of test takers got that question wrong. Here is the question and solution. Also relevant to this question is the definition of the terms 'perennation' and 'perennation organ'

In botany, perennation is ability of organisms, particularly plants, to survive from one germinating season to another, especially under unfavorable conditions such as drought or winter.
Therefore a perennating organ, is an organ that stores enough nutrients to sustain the organism during the unfavorable season

Here's another question that roughly 85% of the you didn't get correct.
In order to do well on this question you also have to understand the definition of 'limiting factors'
A limiting factor is a conditions that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem. Usually a limiting factor is the MAIN thing controlling the population of organisms. For example on land, air would NOT be a limiting factor because it's widely available. Whereas, in some ecosystems, the abundance of food is the main factor controlling population.
