Which of the following statements about energy is TRUE? Question 17 options: It can be used over and over again. It tends to be concentrated by living organisms. It flows in only one direction through an ecosystem. Energy recycles continuously through an ecosystem.

Energy

Explanation:

Energy flows in only one direction through an ecosystem

The Sun supports most of Earth's ecosystemsPlants create chemical energy from abiotic factors that include solar energy and chemosynthesizing bacteria create usable chemical energy from unusable chemical energyThe food energy created by producers is passed to consumers, scavengers, and decomposersEnergy flows through an ecosystem in only one direction, it is passed from organisms at one trophic level or energy level to organisms in the next trophic levelMost of the energy at a trophic level – about 90% – is used at that trophic level and organisms need it for growth, locomotion, heating themselves, and reproductionSo animals at the second trophic level have only about 10% as much energy available to them as do organisms at the first trophic levelAnimals at the third level have only 10% as much available to them as those at the second level

The answer is letter c

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
