Biotic means that something is living, and abiotic means something isn't alive. Paper, since it came from trees, a living thing, is a biotic factor.
Hope this helps!
Message me if you need anything else! I'd be happy to help you! :D
Biotic:
-predator
-competition(relationsip)
abiotic:
-sunlight
-water
The answer is c because many things are losing their habitat and food sources
Answer: photosynthesis
Explanation: In photosynthesis, carbon dioxide and water reacts in the presence of sunlight to produce glucose and oxygen. In photosynthesis, oxygen is released in to the atmosphere while the glucose formed is stored in the plant as food. No carbon is introduced in to the atmosphere during respiration rather carbon dioxide is used up.
In respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide, water and energy. Carbon is introduced in to the atmosphere in form of carbon dioxide.
In forest fires and burning of fossil fuels, wood and fuels burn in sufficient supply of oxygen liberates carbon dioxide (CO2) but when it burns in insufficient supply of oxygen, it liberates carbon monoxide (CO). In both cases carbon is introduced in to the atmosphere in form of carbon dioxide or carbon monoxide.
Answer:DNA, RNA, Ribosomes and Protein Synthesis
This provided the first substantial evidence for the endosymbiosis hypothesis. It was also determined that mitochondria and chloroplasts divide independently of the cell they live in.
Explanation:
<em>What role did endosymbiosis play in the evolution of eukaryotes? Endosymbiosis led to the evolution of eukaryotic cells with mitochondria and chloroplasts. This kind of natural selection led to the evolution of eukaryotic cells and the plants and animals we see today.</em>
