Question

Imagine a world in which there are no seed plants. What would life be like in this world, what would be different from the actual world?

a) No photosynthesis
b) Limited food sources
c) Lack of oxygen production
d) All of the above

Answer 1

Without seed plants, there would be limited food sources and a lack of oxygen production due to a decrease in photosynthesis, drastically impacting the ecosystem and human survival.

Step-by-step explanation:

Imagining a world without seed plants involves considering significant changes to the current ecosystems. The most notable differences would be limited food sources, since seed plants are at the base of the terrestrial food chain, directly affecting all organisms that rely on them for survival, including humans. It would also mean a lack of oxygen production, as seed plants are major contributors to the oxygen we breathe through the process of photosynthesis, where they use water, carbon dioxide, and sunlight to produce sugars and oxygen.Without seed plants, the world would need to rely heavily on non-seed plants like algae, mosses, and ferns for photosynthesis and oxygen production, but these non-seed plants do not have the same efficiency or coverage as seed plants in terrestrial environments. In summary, without seed plants, ecosystems would be drastically altered, leading to decreased biodiversity, food shortages, and changes in atmospheric composition.
