The movement of energy through an ecosystem is and the movement of matter through an ecosystem is

Energy Flow

Biomass

Explanation:

Energy Flow is the movement of energy through an ecosystem.The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem hence giving maintenance to the energy and nutrients in the ecosystem.

Matter is anything that has weight and can occupy space i.e it is said that matter has mass. Therefore, Biomass is the total mass of living or previously living organisms within a trophic level in an ecosystem.

the answer will be a) proteins i believe

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.
