Answer: mode of reproduction
Explanation: Phylum pteridophyte are vascular plants this means they are plants that possess xylem and phloem tissues. Phylum pteridophyte reproduce and disperse by spores. The dominant phase in pteridophyte is sporophyte.
Phylum bryophyte lack true roots and they are non-vascular plants (no xylem and phloem tissues). They reproduce via gamates, the dominant reproductive phase in bryophyte is gametophyte.
The answer to the question is 7.4%.
<h3>How to calculate production efficiency?</h3>
Energy from food is 5000 J
Energy lost in feces is 2300 J
Energy used in cellular respiration (metabolism) is 2500 J
The production efficiency of consumer in an ecosystem is given by
(Energy from food- Energy lost in feces-Energy used in cellular respiration (metabolism)) divided by (Energy from food- Energy lost in feces)
= (5000 - 2300 - 2500)/ (5000 - 2300)
= 7.4
<h3>What is
production efficiency?</h3>
Energy transfer efficiency from one trophic level to the next is referred to as ecological or production efficiency. It is determined by a variety of assimilation and resource acquisition efficiency for organisms within an ecosystem.
The average efficiency of energy transfer between trophic levels is such that net production at one trophic level is often only 10% of net production at the trophic level before it (the Ten percent law). In contrast to being absorbed for production by consumers, a sizeable quantity of energy is lost to the environment as a result of non-predatory mortality, egestion, and cellular respiration. Although these fractions differ significantly from ecosystem to ecosystem and from trophic level to trophic level, the picture roughly represents the fraction of energy available after each stage of energy loss in a typical ecosystem.

Rosalind Franklin. She obtained images of DNA using X ray crystallography.
Answer:
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. So i would think that it is A
