Anni [7]
<span>The answer to this question would be: 
- The permanent thermocline presents a barrier that keeps nutrients in deeper water from mixing with surface waters.
- The sunlight penetrates deep into the tropical ocean, warming the surface waters and creating stratification of water masses.

In tropical lands, the area is getting sunlight all around the year. This will cause the plant to be able to do photosynthesis all around the year too. Sunlight can penetrate the ocean, but the intensity will be much lower in deeper part. The ocean also become warmer but it will become cold in the deeper part too. </span>

Which of the following statements about energy is TRUE? Question 17 options: It can be used over and over again. It tends to be
Law Incorporation [45]
<h2>Energy </h2>

Explanation:

Energy flows in only one direction through an ecosystem

  • The Sun supports most of Earth's ecosystems
  • Plants create chemical energy from abiotic factors that include solar energy and chemosynthesizing bacteria create usable chemical energy from unusable chemical energy
  • The food energy created by producers is passed to consumers, scavengers, and decomposers
  • Energy 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 level
  • Most 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 reproduction
  • So animals at the second trophic level have only about 10% as much energy available to them as do organisms at the first trophic level
  • Animals at the third level have only 10% as much available to them as those at the second level
