Both abiotic and biotic factors determine both where an organism can live and how much a population can grow. A limiting factor is a factor that restricts the size of a population from reaching its full potential
The amount of food & water in a habitat is an example of a limiting factor. Other factors include geographical space, predation, climate, competition (for prey, food, mates) etc. An example of a limiting factor is sunlight in the rainforest, where growth is limited to all plants in the understory unless more light becomes available. Or perhaps in a deciduous forest, there are not enough rabbits to support the growth of more foxes. All species within an ecosystem will experience some kind of limiting factors to prevent continuous and exponential growth. (Even humans) Environmental changes (i.e drought, famine, human destruction) results in decreased rates of physiological processes, lowering the potential for survival, growth, or reproduction. Species will undergo Acclimatization to adjust to the new limiting factors through changing their behavior or physiology.
Photosynthesis would stop
NADP+ is important in photosynthesis because they are significant in both light and dark phases of photosynthesis.
Explanation:
IN the light stage, NADP+ is the ultimate electron acceptor as high energy electrons are passed down a protein chain, from the reactive center of photosystems, as their energy is harnessed to create a proton motive force across the lamellae membrane. NADP+ is ultimately reduced to NADPH. Without NADP+, the electron transport chain would cease.
NADPH, on the other hand, is used to reduce carbon dioxide to glucose in the Calvin cycle. NADPH is oxidized to NADP+ which is recycled back to the light stage of photosynthesis.

Answer:
<em>The correct option is A) increase in atmospheric O2</em>
Explanation:
The nerve cells and the muscle cells suggest that the the presence of oxygen in the atmosphere was an adaptive radiation which brought the existence of different animals. The conditions became favorable for different animals to survive on Earth only when the availability of oxygen improved in the atmosphere. As animal cells like the muscle cells require a constant supply of oxygen, we can hence say that increase in atmospheric oxygen was the adaptive radiation for supporting many group of animals.
