Hi!
Energy will flow through an ecosystem in one <em>direction, </em>from the sun or inorganic compounds to<em> autotrophs </em>and then to various <em>heterotrophs. </em>
The energy flow in an area will be delivering light energy to <em>autotrophs</em>, which make their food from the energy the sun produces.
The energy flow also delivers energy via inorganic compounds to <em>heterotrophs</em>, which do not make their own food.
Hopefully, this helps! =)
Answer: salty and sour
Explanation:
Taste buds consist of the taste receptor cells and they're the nerve endings on the tongue that provide the sense of taste.
Based on the information given, the tastes that activate these receptors are salty and sour. The tastes depolarize the cell receptor directly.
Student 4 is correct. The farther the planet is from the Sun, the less pull it exerts on it.
