Answer:
ample sunlight
steady nutrient supply
Explanation:
Neritic zine is the shallow end of deep water bodies.
This end receives stable temperatures of about 24 degrees celsius.
This area permits photosynthesis since light penetrates to the bottom, this is the reason why planktonic plants survive here.
The region has got steady salinity and because of its favourable nature, it has got many living organisms.
I think the answer is Reproduction.
Forests and other green plants uses carbon dioxide in photosynthesis thus lowering its amount in the atmosphere. In assumption, we can claim that in the ice ages, the low level temperatures may have caused the carbon dioxide levels to neutralize over these phenomenons, also to note that there were less oxygen-breathing organisms and higher carbon-dioxide dependent performing photosynthesis.
There are many different types of specialized cells. This means they are modified by size, shape, or function according to their purpose. Specialized cells make up tissues, tissues make up organs, and organs make up the systems that work together to make up our bodies.
