True or False? As the energy is transferred from producers to consumers, energy is gained.

Answers

Answer:

False.

Explanation:

The food chain may be defined as the sequential tropic levels in which the organism eat other organisms and itself being eaten by other organism. Food chain do not exist in nature.

According to the 10% energy law, the energy is lost from one tropic level to the another tropic level. The 10% energy is available to the next tropic level and the remaining amount of energy is lost as heat. No energy gain occurs as the transfer of energy takes place from the producer to consumer.

Thus, the answer is false.

false because it's using energy to do the work. one way to gain energy is by making it. but yet again this is my thought but like i said it's false.

1. in an ecosystem with four levels—producers, primary consumers, and two higher-level consumers—describe where the decomposers operate relative to the other trophic levels. provide at least two examples of organisms at each level.

Answers

Decomposers, as the name suggests, decompose dead plants or animals into simple compounds. They feed on dead producers from the first levels or consumers from other three levels. Breaking them down, decomposers release nutrients that producers can use.
In an ecosystem with four levels, the first level are producers, such as plants and algae. On the second trophic level, there are primary consumers, herbivores that eat plants, for example, a deer, a rabbit, a grasshopper. The next trophic level belongs to secondary consumers that eat herbivores, for example, a wolf, a fox. The highest level is tertiary consumers that eat carnivores, for example, a bear, an eagle.

A - DNA as the inheritance materials B - RNA as the inheritance materials C - The formation of organic molecules, e.g. nucleic acids, from inorganic precursors

Answers

EXPLANATION:

There are 2 types of nucleic acids: DNA(deoxyribonucleic acid) and RNA(ribonucleic acid).

Living organisms have their genetic material in their DNA. Viruses use RNA as their genetic material but are usually called non-living things( because they can't reproduce without help from a host).

The function of nucleic acids has a progression from DNA to RNA to proteins. This is called the central dogma of molecular biology.

Nucleic acids are formed by a linkage of polynucleotide chains with phosphodiester bonds. These polynucleotide chains are formed from monomers called NUCLEOTIDES.

A nucleotide is made up of 3 parts:

i) a nitrogenous base

ii) a five-carbon sugar

iii) at least one phosphate group.

Answer and Explanation:

DNA as the inheritance materials

Alfred Hershey and Martha Chase state the DNA as genetic material. DNA, or deoxyribonucleic acid, is the natural substance in humans and all other organisms. Every cell in a person's body contains the same DNA. Chromosomes are made up of nucleic acids and proteins and are called hereditary vehicles. ... DNA (deoxyribose nucleic acid) has been found to contain genetic material in all organisms.

RNA as the inheritance materials

• Wandell Stanley, in 1935 proved RNA as genetic material. RNA in humans does not act as genetic material but plays various other roles such as adapters, enzymes, helps in protein synthesis, etc. RNA functions as a messenger for the information to be transferred. The genetic material of organisms and many viruses is DNA. However, some viruses use an alternative type of nucleic acid, ribonucleic acid (RNA), as genetic material. ... RNA has excellent abilities as a genetic molecule; once has to continue the process of hereditary itself.

Nucleic acids

• First, nucleotide are activated, nucleic acid precursors. As such, they are needed for genome replication and transcription of genetic information into RNA. Second, the adenine nucleotide, ATP, is a universal energy currency. Nucleic acids are formed when nucleotide combine through phosphodiester bonds between 5 'and 3' carbon atoms.

Petroleum and coal can be mined from the continental shelf. True or false

Answers

The correct answer would be true. Petroleum and coal are mostly mined from the continental shelf. Most of the oil rigs are found and situated in this area. Gas/oil deposits are found in these areas since the ocean floor is known to exist a 100 million years ago which means deposits and fossil fuels are formed all through out those years.
