Explanation:
Study Island pretest
Consumers eat producers and decomposers get nutrients from both when they die.
What do you mean by consumers?A food chain consumer is an organism that eats organisms from different populations. The consumer is a heterotroph and the producer is an autotroph.
Organisms that eat producers are primary consumers. They are usually small and numerous. The main consumers are herbivores (vegetarians).
Consumers play an important role in the ecosystem by regulating the population growth of organisms and supplying energy to other organisms. Removing any species, producer or consumer from an ecosystem can destabilize the ecosystem.

Which of the following choices contains two ways in which carbon dioxide
enters the atmosphere?"
O A erosion and transpiration
O B decomposition and respiration
C volcanic activity and photosynthesis
Dhuman activity and formation of fossil fuels
Decomposition and respiration choices contains two ways in which carbon dioxide enters the atmosphere.
What is Decomposition?
Decomposition, often known as rot, is the breakdown of dead organic matter into more basic organic or inorganic components such carbon dioxide, water, simple sugars, and mineral salts.
The procedure, which is a component of the nutrient cycle, is crucial for recycling the limited amount of matter that takes up real estate in the biosphere.
Creatures like worms also contribute to the breakdown of the organic compounds. Decomposers or detritivores are organisms that carry out this process.
Therefore, Decomposition and respiration choices contains two ways in which carbon dioxide enters the atmosphere.

How can radio-frequency produce heat?
Answer:
Radio frequency is short for RF, which is a kind of high frequency alternating current electromagnetic wave with frequency range from 3k hz-3k GHz
Because the frequency is high, so the molecular movement speed is fast, and the physical explanation of the heat of the object 100 is its internal molecular movement speed, the use of radio frequency energy to make the molecular high speed movement of course will achieve the purpose of heating
Answer:
Radiofrequency (RF) radiation, which includes radio waves and microwaves, is at the low-energy end of the electromagnetic spectrum. It is a type of non-ionizing radiation. ... If RF radiation is absorbed in large enough amounts by materials containing water, such as food, fluids, and body tissues, it can produce heat.

The dodo bird used to be found in high populations on their island habitat. However, sailors would stop by the island to eat the dodo birds because they were easy to catch. Eventually, the dodo population went extinct.
This is an example of biodiversity loss due to:
Overpopulation
Invasive Species
Habitat Destruction
Overexploitation
Answer:
Overexploitation
Explanation:
Gradual declination of certain species of organisms in an ecosystem, which leads to their extinction occurs from time to time. This is referred to as the loss of biodiversity or simply biodiversity loss. Many factors contribute to the loss of biodiversity in an ecosystem, they include: habitat loss, invasive species, overexploitation etc.
Based on the description of the cause in this question, the biodiversity loss is as a result of OVEREXPLOITATION. Overexploitation is when certain animals are utilized more than the surviving ones can reproduce to cover the loss.
In this case, the sailors overexploited the dodo birds in their island habitat by feeding on them excessively because they were a easy catch.

What are DNA and genetic code?The genetic code is the set of rules by which the nucleotide sequence of a DNA molecule is translated into the amino acid sequence of a protein. A codon is a sequence of three nucleotides that specifies a particular amino acid. There are 64 possible codons but only 20 amino acids, so the genetic code is degenerate or redundant. This means that different codons can code for the same amino acid.
Hence, two humans have some differences caused by mutations in their DNA sequences for insulin, yet they still make the exact same insulin proteins, and this is true. The correct answer is yes; different codons can code for the same amino acid, which is the last option.

What’s air, water, and soils role in the carbon cycle
Answer:
They are reservoirs of carbon in the carbon cycle.
Explanation:
A biogeochemical or nutrient cycle has two major components:
the reservoirs of the biogeochemical or nutrient, andthe processes involved in cycling the biogeochemical or nutrient between the reservoirs.Air is a reservoir of largely inorganic carbon (as carbon dioxide) while water and soils are reservoirs of both organic (e.g. dead decomposing organisms and hydrocarbons) and inorganic forms of carbon (e.g. carbon-containing minerals such as limestone, calcium carbonate).
