Answer:
GOOD IN TERMS OF ENERGY BUT BAD IN THE ATMOSPHERE
Explanation:
BIOFUEL IS AN UNRENEWABLE RESOURCE WHICH IS USEFUL TO US HUMANS INTERMS OF FUEL FOR ENERGY FOR COMBUSTION TO HAPPEN WITHIN THE ENGINES OF MACHINES TO PRODUCE THE ENERGY NEEDED TO DO WORK.HOWEVER IT IS ALSO POLLUTING OUR ENVIRONMENT IN THE PROCESS. SUCH PROBLEMS LIKE GLOBAL WARMING THAT LEADS TO MAJOR PROBLEMS THAT AFFECT HUMAN LIFE .
Answer N0 1)
Lights are left on overnight:
If lights are left on overnight, then the process of photosynthesis will also occur during the night time when the sun is not present. Hence, this method is beneficial.
Farmers can also add fertilizers to the soil:
The addition of fertilizers to the soil allows essential nutrients to be taken up by the plant which will enhance its photosynthetic activity.
Extra carbon dioxide can be pumped into the green house. This comes from the burning of fuel like paraffin which releases. Carbon dioxide as a by-product.
Plants convert carbon dioxide and water into oxygen and glucose during photosynthesis. Hence, this process can be somewhat beneficial.
Fossil fuels are burnt (expensive) to keep the green house nice and warm.
Burning of fossil fuels to keep the green house warm is not an efficient process because this will deplete the natural resources.
Answer No 2)
Plants are protected from unfavourable conditions in a green house. Conditions such as harsh temperatures or harsh wind or floods can completely destroy crop plants. Hence, plants can be grown in the green house where favorable conditions are maintained for their growth.

The food chain in a visual representation of how energy is flowed through out a specific environment. While it is very similar to the food web, the main difference is that the web gives a more broad wide range of organisms and it is more specific with what eats what. The second part of your question about a few animals roles umm... Grass is a producer which has the role of feeding primary consumers, it is the base of the chain or web without it the whole thing would collapse. Tertiary consumers such as owls have the role of eating secondary consumers. I always thought of it like the tertiary consumers are population control since nothing eats them they have no responsibility to feed other organisms just make sure that secondary consumers don't overpopulate.
The process is called photosynthesis and it takes place in the chloroplast of a plant cell
