<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
Answer: Replication
Explanation: When the cell is preparing to divide it will <u>replicate</u> its DNA so that both of the daughter cells will have a complete set of the DNA. It's like a book of instructions and the cell has to perfectly replicate it so that when it splits into two both of the new cells will have a perfectly made copy of it! Hope this helps :)
the area of the square is: 100
the area of the circle is: 78.5
i THINK if you subtract it, it will be 21.5
The big bang theory states that the universe began approximately 10-20 billion years ago in an expansion of the universe emanating from an extremely compact point. The occurrence of super massive black holes contradict the big bang theory. Super massive black holes are found at the center of galaxies and is what keeps them together. Models do not explain how these would have formed if the big bang occurred the way it was proposed.
The remains of fossils give scientists clues as to what the world may have been like a long tome ago. If fish fossils are found on the side of a mountain, there may have been a lake there. If a skeleton is found, they can decide what creature it was.
