which statement explains how producers are dependent upon consumers for their survival?
consumers supply oxygen for producers to undergo aerobic respiration.
consumers produce carbon dioxide for producers to use during
photosynthesis.
consumers provide chemical energy needed by producers for cellular
respiration
consumers make lactic acid that producers use in photosynthesis.

Which statement explains how producers are dependent upon consumers for their survival?

The correct answer is:

Consumers produce carbon dioxide for producers to use during photosynthesis.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.

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.
