Owls eat rats, mice, shrews, and small birds. assume that, over a period of time, an owl consumes 5,000 j of animal material. the owl loses 2,300 j in feces and owl pellets and uses 2,600 j for cellular respiration. what is the production efficiency of this owl

The production efficiency of this owl is %

Explanation:

Given -

Energy from food J

Energy lost in feces J

Energy used in cellular respiration (metabolism) J

The production efficiency of consumer in an ecosystem is given by

(Energy from food- Energy lost in feces-Energy used in cellular respiration (metabolism)) divided by (Energy from food- Energy lost in feces)

Substituting the given values in above equation, we get -

%

Hence, the production efficiency of this owl is %

the correct answer is:

a population changes in response to a change in the environment.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
