What would happen if the amount of sunlight reaching the Earth's surface decreased?

Answer 1

Plants require sunlight to produce their food, without sunlight plants would die from starvation.

If the plants all died then the animals that eat plants (herbivores) would also run out of food and die of starvation.

If herbivores ran out of food and died then animals that eat other animals (carnivores) would run out of food and die of starvation.

Once all the plants and animals were gone, insects, bacteria and fungus would have no food supply left either and would also die.

This is an extreme example based on the loss of ALL sunlight. If the amount of sunlight were to just decrease then we would expect a much less extreme result. Less sunlight would result in less plant growth, less food for herbivores, less food for carnivores, etc. The amount of life that the earth could sustain would decrease but would not in my opinion disappear altogether.

Answer 2

then the plants will die due to lack of food production, andthen the primary consumers will die beacues of lack of plants and then the secondary consumers and then the tertiary consumers and the finally the quantenary consumers..and so on and so forth

Answer 3

1. The amount of plant life would decrease

2.The population of primary consumers would decrease.

3.The population of secondary consumers would decrease

Answer 4

Without sunlight the ecosystem would lose plants making herbivores starve and die. If herbivores die carnivores would starve. Then we would not eat anything.
