Answer:
The correct answer to the question is Biofuel
Explanation:
Biofuel can be used as an alternative energy technology source to power a car.
The importance of using biofuel is that it causes less air pollution than fossil fuels, and it has less effect on the global warming. Most importantly, it is produced from agricultural sources.
The biofuels that can be used are butanol,ethanol and biodiesel etc.
Wind, geothermal and hydropower can not be directly used to provide power to the car.
Hence, the correct answer to the question is that biofuel which can be used as an alternating technology to provide power to car.

The answer is 7.4%.
Percentage of trucks on the lot is equal to the ratio between the number of trucks and the total number of cars.
- Number of trucks ÷ Total number of cars
- 49 ÷ (49 + 612)
- 49 ÷ 661
- 7.4%

13. second
Explanation:
An ecosystem consists of a community of living organisms
interacting with each other and the environment. The source of energy that fuels most ecosystems is the sun. Plants use the Sun’s energy to produce food in a process called photosynthesis.
Organisms that use energy from the Sun or energy stored in chemical compounds to produce their own nutrients are called autotrophs. They are also called producers because most other organisms depend on autotrophs for food and energy. Heterotrophic organisms that can’t make their own food may obtain nutrients by eating other organisms. A heterotroph that feeds only on plants is called an herbivore. Herbivores are also called first order heterotrophs. Heterotrophs that feed on other herbivores are second order heterotrophs.
