It is true that r-related species have a short life span and an early reproduction cycle. R-related species also known as r-strategist have a short and simple life span. Due to their simple life span, their nutrient exchange rate with the environment is rapid. Unlike K-selected species, they have the ability to reproduce at a young age. They reproduce a large number of off-springs, but many of their off-springs tend to die before attainment of their reproductive age.
<span>There is no primary root. Innumerable thin roots of similar size are present.</span>

According to the research, a tropism is a plant's response to external stimuli like light, gravity, and touch.
<h3>What is a tropism?</h3>
It is the response that plants or certain organs of them make to a stimulus that comes from the outside.
There are different classes of tropisms according to the nature of the stimulus, gravitropism, phototropism, heliotropism among others.
Therefore, we can conclude that according to the research, a tropism is a plant's response to external stimuli like light, gravity, and touch.

Think of a sponge. The more porous (ability to absorb, what happens to that sponge?) it is more permeable (ability to move). A
