CO2 + H2O = O2 m + C6H12O6 photosynthesis
C6H12Og + O2 = CO2 + H2O + ATP respiration
For many species, there are often regional differences in their genes, although most of the time this differences aren't noticeable in their outward appearance.
Environment, genetics, selective breeding, random mating, random fertilization, recombination, crossing over, etc
The answer is A, as bears don’t eat deer, but they both eat plants.
Heterotrophs are animals.
Autotrophs are plants.
Hope this helps!
Cyanobacteria don't need oxygen to survive they produce oxygen. They where the first ever known organisms on the planet and they produced oxygen in the oceans which was absorbed by iron deposits and then once the iron had oxygen the ocean got the oxygen until it got into the atmosphere and Eukaryota bacteria evolved. So the answer would be: <span>They convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere.</span>
