“Unlocking the Green Puzzle: How Photosynthesis Powers Earth’s Survival and Secrets”
Why Photosynthesis Is Important
Here are some of the ways photosynthesis is vital to fueling life on Earth:
The Byproducts of Photosynthesis Are Critical for Humans and Animals
From a plant’s perspective, once it has created its food, the byproducts, such as oxygen have no value. However, these two are critical in fueling life here on Earth. To begin with, oxygen is used by organisms such as humans and animals for breathing.
On the other hand, humans and animals release carbon dioxide when they breathe out, which is re-used by plants. This creates a symbiotic relationship. Also, when plants absorb carbon dioxide from the air, they regulate Earth’s temperatures while keeping greenhouse gases in check.
It’s Important for Food Chains to Exist
When plants make their own food through photosynthesis, they can grow and sustain themselves. Additionally, animals, such as herbivores, feed directly on plants and convert them into energy. Next on the food chain are omnivores, like human beings who eat both plants and animals. The described food chain would not exist if plants did not synthesize food.
Besides offering food and oxygen to organisms on Earth, photosynthesis creates habitats for our ecosystem. Animals and other organisms live in forests. Humans rely on plants to process non-food items such as lumber for construction, paper, and much more.
An excellent way to make people appreciate photosynthesis is by having them compare our sister planets, Mars and Venus. After the Big Bang, these three planets were formed using the same heating and cooling mechanism. However, the composition of gasses on these three planets is different.
