It is true that organic compounds have one or more carbon atoms covalently bound to other atoms like hydrogen, oxygen etc

Examples of organic compounds include:

Answer:

Petroleum

Hydrocarbon gas liquids

Natural gas

Coal

Nuclear energy

Explanation:

These energy sources are called nonrenewable because their supplies are limited to the amounts that we can mine or extract from the earth. Coal, natural gas, and petroleum formed over thousands of years from the buried remains of ancient sea plants and animals that lived millions of years ago. That is why we also call those energy sources fossil fuels.

Most of the petroleum products consumed in the United States are made from crude oil, but petroleum liquids can also be made from natural gas and coal.

Nuclear energy is produced from uranium, a nonrenewable energy source whose atoms are split (through a process called nuclear fission) to create heat and, eventually, electricity. Scientists think uranium was created billions of years ago when stars formed. Uranium is found throughout the earth’s crust, but most of it is too difficult or too expensive to mine and process into fuel for nuclear power plants.

ale4655 [162]

Answer:

<u><em>The correct answer is:</em></u><u><em> </em></u>  sustainability over time with varying conditions.

Explanation:

A habitat can be defined as the physical and geographical conditions that will positively influence the development of life, in any form.

Therefore, it is correct to say that sustainability over time with favorable conditions will favor the greatness of the habitat.

Sustainability is the ability to preserve a system for the maintenance of future life, so it is ideal for there to be sustainable development across society, so that natural resources are preserved so that biodiversity continues to exist.
