<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:
1. When the number of calories a person consumes is equal to the number of calories he or she burns in a day, that person's body is in Energy Balance.
2. Someone who is in Positive Energy Balance eats more calories in a day than he or she bums.
3. Negative Energy Balance occurs when the number of calories a person bums in a day is greater than the amount he or she consumes.
4. Weight management involves applying strategies that allow someone to keep his or her body weight within a healthy.
5. The Basal metabolic rate is the amount of energy uses in order to perform its basic physiological functions.
6. The Thermic effect of food refers to the number of calories burned in order to digest absorb, metabolze, and store food.
7. The Lean body mass refers to his or her total body - fat mass.
Explanation:
This group of statements are related to body weight, the balance between the energy we consume through food and all the energy we burn through excercise and different activities, such as only mantaining our body temperature and normal processes.
Answer:
im taking this test right now whats the answer please
Explanation:
Answer:
a. It's a carrier protein doing facillitated diffusion
Explanation:
Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.
The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.
