Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Summarize this quote into a couple of sentences. 

“In 2007 I argued that Facebook might not be around in 15 years. I’m clearly wrong, but it is interesting to see how things have changed,” says Jonah Berger, Wharton marketing professor and author of Contagious: Why Things Catch On. The challenge going forward is not just having the best features, but staying relevant, he says. “Social media isn’t a utility. It’s not like power or water where all people care about is whether it works. Young people care about what using one platform or another says about them. It’s not cool to use the same site as your parents and grandparents, so they’re always looking for the hot new thing.”
Response: Marketing professional and author of the book Contagious: Why Things Catch On, Jonah Berger stated in 2007 that Facebook wouldn't be as popular within 15 years. Now he states that it's important for social media platforms to remain relevant and have something new to offer in order to compete and remain popular with younger audiences. 

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Condense the following explanation into a concise summary: 

"Photosynthesis is the process by which green plants, algae, and certain bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose. This process involves the absorption of carbon dioxide and water, which are transformed into glucose and oxygen through a series of chemical reactions powered by sunlight. Photosynthesis is essential for the survival of life on Earth as it provides oxygen for respiration and the basis of the food chain."
