1. Trees are tall, woody plants that typically have a single main trunk and branches. They play a vital role in our environment by providing oxygen, absorbing carbon dioxide, and supporting biodiversity. Additionally, trees offer shade, timber, and various other resources.

2. Regarding the question about the limited supply of resources, it depends on the specific resource in question. Some resources are finite, meaning there is a limited amount available and once it is exhausted, it cannot be replenished. Examples of such resources include fossil fuels like coal, oil, and natural gas. These resources take millions of years to form, making them essentially non-renewable at the human time scale.

4. Coal is a fossil fuel formed from the remains of plants that lived and died millions of years ago. Coal is abundant in some parts of the world and is often used as a fuel source for electricity generation and industrial processes. However, as a non-renewable resource, its supply is limited, and it takes millions of years to form.

5. Petroleum, also known as crude oil, is a fossil fuel that is formed from the remains of ancient marine organisms. The process of petroleum formation occurs over millions of years under specific geological conditions. It involves the accumulation, burial, and transformation of organic matter deep beneath the Earth's surface. Due to this lengthy and complex process, petroleum is considered a non-renewable resource with a limited supply.
