light is essentil for the life of animas. they compensate the defeciency of vtamin D through light ...
Plants need light to make food, we need light to see, and without plants animals wouldn't eat, without animals and plants we would die.
Without animals everyone would die unless you were a vegetarian.
Heat is another requirement of life, Without Heat, us being Warm blooded animals would die due to Hypothermia! Light and heat are interconnected absence of Heat indirectly means absence of light too, so even if you survive escaping hypothermia(unlikely) you would die due to starvation as the chief producers Plants die as they cannot survive without light! Even cold blooded animals die of starvation. Only few types of bacteria might be able to survive!
Without the sun, Earth would be in darkness except for minimal light from small stars and the moon. Plants would not survive due to lack of sunlight. Without plants animals would not have food and would also die.
yes
because without it animals and humans would die!
well thousands of animals rely on wetlands. Without wet lands hundreds of creatures like beavers, some fish, crocodiles, turtles, frogs, Miskitos, dragon flies and a lot would die. Each wetland may contain entire ecosystems. Other animals that feed in the wet lands would die. Then the animals that feed on those animals will die then the once that eat those animals would die and on. Without wetlands thousands of animals would die
They would dehydrate without it, and die.
Because without it the green algae would not be able to photosynthesis and would eventually die. This would mean that there would be no oxygen (O2) being produced for the animals as well as their food (Glucose C6H12O6) supply being cut.
Lost if not all marine animals are aerobic. This means that without oxygen they will die. As only plants and some species of fungi or bacteria produce oxygen, without plants (water dwelling plants) then aquatic animals would die.
Without light, grass would not be able to photosynthesize and create food for itself. Eventually, the grass would die due to lack of energy and nutrients.
We would all freeze because there was no light, therefore, we would all die.
