ASAP please answer all again this I a huge assignment and I need help. Will mark crown/Brainliest

1) In ecosystems, matter and energy are transferred from one form to another. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers.

2) Matter cycles through an ecosystem through processes called biogeochemical cycles. All elements on Earth have been recycled over and over again, the tracking of which is done through biogeochemical cycles.

3) Sunlights ---> Chemical Energy > Heat

the correct answer is c   with the systems

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.
