Answer
Light is necessary for life on Earth. This is because it is indispensable for photosynthesis, a process which produces glucose (a necessary nutrient for many living organisms) and oxygen (a vital element necessary for animal survival and overall maintaining global ecosystems).
Explanation
## Step1: The question asks us to complete the sentence “Light is necessary for life on Earth. This is because…" with an appropriate explanation.## Step2:Through providing light, the sun contributes to the successful performance of photosynthesis, a process that plants undergo to convert accessible light energy into biochemical energy in the form of glucose. At the same time, oxygen - crucial for animal respiration - gets released into the environment through this process.## Step3:Analytics show that photosynthetic organisms provide as a base for other organisms within their respective ecosystems by fundamentally being the primary producers, producing glucose for their own consumption and that of others. Thus, light is vital to maintaining these ecological constructs due to its requisite role within photosynthesis.## Step4:The concluding sentence related to the need of light now becomes both nuanced and multi-tiered instead of one dimensional.
