Answer:

the average percentage of energy lost as heat

Explanation:

An energy pyramid (also called trophic pyramid) is a graphical representation that exhibits how energy flows at each trophic level in a particular ecosystem. In an energy pyramid, it is possible to determine how much energy is available at each trophic level and how energy flows from producers (e.g., photosynthetic plants) to primary consumers (e.g., herbivores), then from primary consumers to the next trophic level (e.g., carnivores), and so successively to all major trophic groups (e.g., higher carnivores). During this chain, energy is lost as heat when it is transferred to the next level, and the average percentage of energy lost increases at each trophic level, thereby less and less energy is available to major trophic groups.

What early concept of heredity proposed that genetic information in the form of particles called gemmules travels from different
Contact [7]

Answer:

Pangenesis

Explanation:

The theory of 'pangenesis' was proposed by Darwin to explain the process of inheritance of genetic traits from one generation to next. According to this theory, gemmules are the tiny particles produced by all the somatic cells of the body of living beings. These gemmules are also called pangene. Blood carries gemmules from all the body cells to the gonads. These gemmules from all the somatic cells form germ cells in gonads.

How is the equilibrium constant calculated?
larisa [96]
The answer is the equilibrium concentrations or pressures of each species that occurs in the equilibrium expression, or enough information to determine them. These values are substitued into the equilibrium expression and the value of the equilibrium constant is then calculated.
