Answer: Energy is not recycled once it passes from producer to consumer to decomposer.
The energy flow in an ecosystem in the form of food from one organism to other is food chain. It comprises mainly of three types of organisms producers or autotrophs, consumers or heterotrophs and decomposers. The energy flow in food chain or food web is unidirectional from plants which are the primary producers to primary consumers or herbivores, then to secondary consumers or carnivores and finally to the decomposers. On its unidirectional flow the energy is lost in different form such as heat loss, decay, respiration etc. The energy passed from one level to another is not the same and gets lost in the process so when the energy is received from one tropic level to another it is always less than that received by the previous tropic level.
Answer:
Transcription is the first of several steps of DNA based gene expression in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.

Mapping the human genome was a project that was completed in the 20th century, and was named "The Human Genome Project". Its goal was to document all 3 billion DNA base pairs in the human genome, and to find the 25,000 human genes. Its main benefit in the field of medicine is locating chromosomal abnormalities that cause diseases before they develop into chronic, life-threatening diseases.
Answer:
It was found on Earth’s surface.
Explanation:
Igneous rocks are formed either<em> on the surface of the Earth</em> or <em>deep in the Earth's crust.</em> Those formed on the surface of the Earth are called <em>"Extrusive Igneous Rocks" </em>while those formed in the crust are called<em> "Intrusive Igneous Rocks." </em>
An igneous rock which has<em><u> small, dark crystals</u></em> is an extrusive igneous rock (this makes the first choice incorrect). It was formed through "rapid cooling," thus, it's texture is<em> fine</em> (this makes the last two choices incorrect).
Since it is an extrusive igneous rock,<u> it can be found on the Earth's surface. </u>This makes the third choice correct.
