First of all, pterophyta have neither seeds nor flowers in the first place.. Angiosperms are flowers and are the most diverse group of land plants so I doubt they would be losing its seeds... Lastly gymnosperms are a group of seed producing plants.. According to what I just wrote, what do you think the answer is??
Answer: Yes! there is life in the stratosphere but not the type you think, it's actually microbial life forms that live on it.
Trophic levels go by,
Producer (The nuts)
Primary Consumer (Squirrels)
Secondary Consumer (Raccoons)
Tertiary Consumer (Bear)
So squirrels would be at a lower trophic level.
Hope his help :)
