Answer: They tend to support large planktonic
communities because (of higher dissolved oxygen and nutrient concentrations).
Explanation:
Planktonic communities are made up of basic organisms that forms the oceanic food web. They are broadly divided into Phytoplankton (these are the producers), Zooplankton (these are the consumers) and Bacterioplankton (these are the recyclers).
High-latitude ocean water is mostly affected by the quantity of oxygen and nutrients it contains. Large planktonic communities thrives in these aquatic environment because is contains higher amount of dissolved oxygen and nutrient concentrations which forms part of their basic needs for survival. This is so because changes in ocean water can impact all levels of the food web. Increase or decrease in ocean temperature can modify the plankton diversity and distribution directly by altering it's metabolic rates and growth.
Therefore due to the geographic location of high latitude ocean, higher dissolved oxygen and nutrient concentrations favour the survival of a larger planktonic communities than other ocean parts.
Answer:
c. More oxygen and less carbon dioxide
Explanation:
The composition of air in the layers between the soil is called soil atmosphere or gas.
The maximum percentage of gas in soil is nitrogen with 79.2 %. Then it is oxygen with 20.6 % and the last is carbon dioxide with 0.25 %. These gases are required in order to maintain life under the ground. The roots of trees and the microorganisms require soil atmosphere to carry out their functions.
The answer is B.
Animals do cellular respiration which requires the intake of oxygen and the output of carbon dioxide. In order for plants to do photosynthesis, they need carbon dioxide to be able to make oxygen for animals to breathe.
Chordates, or members of phylum Chordata, possess a backbone.
