Why is photosynthesis is so important to life on earth?

It is the key factor to our survival. Photosynthesis is what keeps oxygen flowing and Humanity still alive. First we can look at the process itself. Plants breath in Co2, and releases oxygen which is vital for us. Co2 is a substance found in our atmosphere which too much of it, can kill people. This is why photosynthesis is here. Without the proccess, much of our atmosphere would be filled with unbreathable gases. This will result in many fatalities and eventually the loss of humanity.

We could also look at this at the plants' side. Humans continue to kill many of the much needed plants that hold our future. For them, they require photosynthesis greatly as well. They must "breath" in the Co2 to keep their bodies alive. If plants were to stop "breathing," humans would stop having oxygen, and if humans stop having oxygen, they die.

Another bad effect without it, can last on animals. Animals, much like humans, need oxygen to breath. Whether it is very short, or a large amount, they all need oxygen just like us. It is important for animals to sustance life here on Earth. Not only for the enviroment, but for the future the beholds unknown.

In conclusion, photosynthesis is something every species need. Whether it's plants, animals, or humans, photosynthesis is required for our survival. Without it, no species would exist. This is why humans need to stop destroying vital plant species and realize the true consequences.

the answer is "a.) well–developed vascular system."

explanation:

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
