Answer:
Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.
Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
Answer:
(a)-Kinesthetic
Explanation:
- The <em>Vestibular sense </em>is responsible for our sense of spatial orientation or balance.
- The Auditory sense is responsible for the perception of sounds.
- The Umami Olfactory sense is responsible for our sense of smell and taste.
So the answer is (a), kinesthesic. It is thanks to the kinesthetic sense that we can go up stairs easily without stopping to see and carefully control the movement of each of our legs.

Hypothalamus
Explanation:

Explanation:
The answers are: C D E. Cells are semi-permeable which means it chooses what nutrients and h2o to enter and excretes cell waste into the bloodstream.
Answer: RuBisCO is very important in biology and ecology because it catalyzes the primary chemical reaction by which inorganic carbon permanently enters the biosphere. RuBisCO is also the most abundant protein in leaves and the most abundant protein on Earth.
