Question

Describe the sun’s role in the sustainability of the Earth’s environment.

Answer 1

The sun is the main source of all our resources. If the sun was to die out we will have no light. No means of growing crops. Without the sun the entire environment will collapse. Especially since the plants rely on the sun to produce photosynthesis (who they make food)

Answer 2

Without the sun, most/all life would cease to exist, especially once depending on light energy from the sun like plants, forming the bases of life.

Step-by-step explanation:

Plant (producers) use light energy to photosynthesis, producing the energy or food other herbivores (plus, our primary&secondary consumers) dependant upon, to survive; then, they get preyed upon (by our tertiary consumers) - structuring the food chain as we all know of. Hence, sustaining life/ living organisms on earth, for generations to come.

Thus, all life on earth as we know it, basically, won't exist. Abiotic factors are the one's to live a happy ever after. There are non-living, once that don't undergo cellular respiration like us humans, e.g., rocks don't respire.

Anyways the sun is a star, one day (millions to billions years onwards) it's predicted to engulf our earth, when transitioning to become a red giant. So, it might not sustain earth forever.

Don't panic, you won't live to experience this! How fantastic does this sounds?

Hope this helps!
