Producers: Producers <span>are basically organisms that make their own food. They get energy from chemicals/and or the sun, and with the help of water, they convert that energy into useable energy in the form of sugar, or food. Plants are one very good example of a producer.
Consumers: Consumers a</span><span>re essentially organisms which receive energy by consuming other organisms. These organisms are commonly referred to as heterotrophs, which include animals, bacteria, and even fungi.
</span>Decomposers: Decomposers <span>are organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition.</span>
Option (a) has a greater chance of being the answer — the respiratory system does take in Oxygen to break down glucose into Carbon dioxide and water vapor, releasing energy.
Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele.
