Why do plants in early seral stages exhibit high levels of tolerance?

Question

Quizplus · Accepted Answer

Plants in early seral stages, also known as pioneer species, must deal with harsh conditions such as fluctuating temperatures, limited nutrients, and minimal soil development. These conditions require a high level of tolerance in order for the plant to survive and grow. Therefore, option B is the correct answer. Option A is incorrect because early plants do inhibit the growth of other plants (through shading and nutrient competition). Option C is incorrect because pioneer species are actually strong competitors for resources in their harsh environment. Option D is incorrect because many pioneer species have large, wind-dispersed seeds that germinate well in open, sunny areas.
