Explanation:
Plants have been using light in this primal way for a large chunk of Earth's existence. But just how did they gain the ability to photosynthesize? The short answer is they stole it, about a billion and a half years ago, when single-celled organisms called protists engulfed photosynthesizing bacteria.
Answer:
Sun > Grass > Deer > Lion
Explanation:
The sun begins a food chain because its light is needed for a plant, in this case grass, to grow.
An animal that eats grass is the deer, who is a primary consumer.
An animal that eats deer is the lion, who is a tertiary consumer in this case.
The lion has no natural predator, and thus is at the top of this food chain.
This ecosystem can be one found where grass, deer and lions exist, for example, the deciduous forest in the eastern United States.
If a portion of the grass was destroyed by wildfire, then the population of bison that feed on the grass will decrease. This is because there would be very little grass left for them to eat, and they don't eat anything else.
1- they can be used as domestic fuel for cooking instead of kerosene or firewood that contribute to pollution
2-they can also used to generate electricity in rural areas as these areas has not enough resources of electricity
