Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.
The term biotic factors has been defined as living factors present in the ecosystem. Biome is a separate biogeographical region that contains its own living and non-living factors along with a characteristic climate. The examples of biomes are: Tundra, Temperate, Desert, etc.
Changing a biotic or abiotic factor can affect each other or even the entire biome because these factor live in a state of dynamic equilibrium by being interdependent on each other. Therefore, if this equilibrium is disturbed then the survival of some living organism may be disturbed that can eventually lead to ecological succession.
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community.
Therefore, Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.

Hemoglobin is a crucial component of the circulatory system. It is a protein found in red blood cells that plays a central role in oxygen transportation. Therefore, the correct option is option 2.
The circulatory system, also known as the cardiovascular system, consists of the heart, blood vessels, and blood. Its primary function is to deliver oxygen, nutrients, hormones, and other essential substances to the body's tissues and organs.
In the context of the circulatory system, hemoglobin binds to oxygen in the lungs and carries it to the body's tissues, where it is released for cellular respiration. Additionally, hemoglobin helps transport carbon dioxide, a waste product of cellular metabolism, from the tissues back to the lungs, where it can be exhaled.
Therefore, hemoglobin's function and presence in red blood cells are closely associated with the circulatory system. Its role in facilitating oxygen and carbon dioxide exchange ensures the proper functioning and survival of cells and organs throughout the body.
Thus, the ideal selection is option 2.
