What percentage of algae uses photosynthesis to make their own food?0%
15%
50%
100%

Answers

Answer 1

Answer: The answer would be 100%. The answer cannot be 0% becausesurely algae produce food through photosynthesis. Also, it cannot be 15% and 50% because it is difficult to be really that precise. Algaes contain chlorophyll which is an essential component for producing their own food via photosynthesis. This is the only process for them to obtain their own food. Thus, 100% of algae uses photosynthesis.

if mosses and ferns grow in an environment that is dry and where water is limited, wich of the two plants would be the most affected?

Answers

Mosses because moss needs to absorb water and moisture to stay alive

Final answer:

In a dry and water-limited environment, mosses would be more affected than ferns due to their dependence on moisture for survival.

Explanation:

In an environment that is dry and where water is limited, mosses would be more affected than ferns. This is because mosses are non-vascular plants that do not have true roots, stems, or leaves. They rely on water absorption through their leaf surface and require moist conditions to survive. Ferns, on the other hand, are vascular plants that have specialized tissues for water transport. They have true roots, stems, and leaves, allowing them to better cope with limited water availability.
