the origins of life on Earth? This question has been highly debated by scientists for a long time. Scientists are trying to determine what makes Earth so unique that life thrives here but in no other planets that we are aware of. There are several theories that scientists have proposed in trying to determine the origins of life on Earth.

The Earth is one of eight major planets and a host of minor planets that circle a fairly average‚ middle-aged‚ main-sequence star. It formed from the accretion of residual material from the gravitational collapse of the solar nebula that produced the Sun. Based on their specific distances from the Sun‚ the planets formed into groups of similar chemical compositions‚ sizes‚ and densities. The four smaller inner planets are of higher density and are composed of a mixture of rock and metal. In contrast

1. Define autotroph and heterotroph and give an example of each. (1 point) Autotroph refers to the process of collecting energy from sunlight. This type of energy is fundamental for plants in order for them to survive‚ so we can conclude that plants are an example of an autotroph. Heterotroph refers to the process of collecting energy by consuming substances/products like meats‚ fats‚ carbohydrates‚ fruits‚ etc. Humans are an example of heterotroph since they are the ones who perform this process
