B) Photosynthesis The Sun is the ultimate source of all energy in the universe. Plants being the main primary producers or autotrophs, use solar energy to make their own food through photosynthesis, thus converting energy into the organic matter that can be consumed by all organisms. They  form the basis of almost all food chains from where consumers derive their food.
        
                    
             
        
        
        
Answer:
<em>They will have a large number of genetic variations.</em>
Explanation:
Genetic variations arise due to sexual reproduction or due to the process of meiosis.  
Cross-pollination can be described as a process in which the pollen of one flower is transferred to another flower. The pollen when fertilizes the egg in the stigma, will produce offspring with varied genetic characteristics. This will be because the pollen would carry the trait of another flower and the egg of another flower. This will lead to many genetic variations. 
 
        
             
        
        
        
Answer:
Abiotic factor.
Explanation:
Soil type is an abiotic factor for an earthworm. The soil type helps an earthworm to collect food and increase the population. 
Sunlight, soil, water, and rocks are those abiotic factors that contribute to earthworms to obtain their food and to survive under the soil or upper side of the soil. 
Like earthworms, many other organisms depend on the abiotic factors for their livelihood.
