Are plants essnetial to life? And if so why?

Answer 1

Yes they are. When we breathe, we take in oxygen, and convert it to carbon dioxide. In turn, plants take in carbon dioxide and convert it to oxygen. It goes full circle and we work off of each other. Also, since all sources of energy ultimately comes from the sun, all plants need it to grow. When we eat plants and vegetables, it converts to energy, so our bodies work.

Answer 2

Plants take in carbon dioxide and release oxygen as part of photosynthesis. Since most land-based animals (including humans) require oxygen to breathe...and plantlife is the largest producer of oxygen...we would have a hard time existing without plants and trees on Earth.

Answer 3

yes
they use our carbon dioxide that we breath out to make oxygen which we breath in
they also provide energy through sugars
an animal eats plants and gets energy from them and even if you arent a vegetarian and only eat meat the energy that you get from the meat came from the plant in the first place
so yes plants are essential to life

Answer 4

Plants give off oxygen and also many animals count on them for a food source.

Answer 5

Plants help produce oxygen which we need to breathe so yes!

Answer 6

Yes. I think so. Plants produce oxygen. Without them (and algae) the world would become hot, muggy, and unbearable.

Answer 7

Yes plants produce oxygen which hels us to breath.

Answer 8

yes because they we breath out carbon dioxide which is then converted back into oxygen by plants

Answer 9

Yes.
They release Oxygen into the atmosphere.

Answer 10

Yes they are because they give people air and take away the carbon dioxide in the air.
