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.

</span>The milkweed is the primary producer in the
ecosystem. It manufactures food from the abiotic factors in the soil such as
nitrates and water and those in the atmosphere such as carbon-dioxide and
sunlight. The milk weed is then fed on by the caterpillar and a primary
consumer. The caterpillar is then fed on the mocking bird (secondary consumer)

</span>Increased human population growth and their activities
have resulted in the emission of carbon dioxide and other greenhouse gases in
the atmosphere. This has increased the global temperature. This increase of
global temperature increase ocean temperatures causing coral bleaching.
Another example is depletion of water sources
by human activities hence causing drought. Drought reduces the amount of
vegetation growth due to scarcity of water in the soil (due to lowering of the
water table) for plant growth.
