➜ The conditions necessary for autotrophic nutrition are sunlight, chlorophyll, carbon dioxide (CO2) and water (H2O).
The byproducts of autotrophic nutrition are water and oxygen.
Spindle fibers extend from the poles and overlap at the spindle equator where some attach to chromosomes to help separate them during cell division.
<h3>What is spindle fiber?</h3>
A single filament that travels from the poles to the center is a spindle fiber. Aster is a single filament as well, but the aster differs in its placement.
<h3>What is spindle equator?</h3>
Chromosome alignment at the spindle equator improves the efficiency of bi-orientation. Chromosome congression, a procedure that moves chromosomes from close to spindle poles to the equator, is necessary for this alignment to take place.
<h3>What is spindle in cell?</h3>
A protein structure called a spindle fiber divides a cell's genetic material.

We can decrease overall atmospheric CO2 by increasing photosynthesis rate or reducing cellular respiration.
<h3>What is cellular respiration?</h3>
Cellular respiration is a process by which aerobic cells can produce energy and carbon dioxide by using the chemical energy of foods and oxygen.
Conversely, photosynthesis produces carbohydrates and oxygen by using carbon dioxide and sunlight.
In conclusion, we can decrease overall atmospheric CO2 by increasing photosynthesis or reducing cellular respiration.
