Answer:

Explanation:

Wood has_chemical energy_____ energy while a burning fire has__heat energy __ energy

Wood is a material that makes up the central part of the trunk and branches of trees. Wood is made up of complex hydrocarbons and a rich cellulose network of organic molecules. A wood stores chemicals energy.

Combustion process such as burning liberates heat energy in them. Burning occurs in the presence of oxygen. As the oxygen combines with the materials, heat becomes liberated to the surroundings. Burning is an exothermic process in which heat energy is liberated.

The producers had 6,000 kcal of energy , how much would be passed to the primary consumer?
morpeh [17]

Answer:

600 kcal

Explanation:

In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.

Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.

Compare and contrast genetic engineering to the process of natural selection select all statements that are are
alisha [4.7K]

Genetic engineering is due to the human selection of desired phenotypes, whereas natural selection is a slow process of differential survival and reproduction.

<h3>What does natural selection mean?</h3>

According to the evolution theory, natural selection is a slow process of differential survival of the fittest organisms in a given environment.

Conversely, genetic engineering refers to the molecular biology techniques used in the laboratory to produce organisms expressing desired phenotypes.

In conclusion, genetic engineering is based on human molecular biology techniques, whereas natural selection refers to differential survival and reproduction in nature.
