Answer: a naturally occurring depsipeptide used in the transport of potassium
Energy moves from one trophic level to another as organisms feed on one another.
Explanation:
Energy flows from one trophic level to another in a food chain. according to the ten percent law, only ten percent of the total energy passes onto the next trophic level. While studying the energy flow model two aspects should be taken under consideration. Firstly, the flow of energy is unidirectional and passes on from autotrophs to primary consumer and then secontary, tertiary so on. Secondly the amount of energy decreases at succesive trophic level.
Answer:
If a cell can't control what enters and leaves its structure, harmful and foreign substances can get into the cell and obstruct cell activity.
Explanation:
Mark brainliest if possible and have a great day : )
The amount of total energy at each trophic level decreases as it moves through, so 90% is lost at each level. This means that only 10 percent of the energy at any trophic level is transferred to the next level; and the rest is lost as heat.
In this case, if a plant ecosystem has 3000000 kilocalories (kcal) of energy, about 300000 kcal will be transferred to primary consumers (for example grass hoppers). If the red-tailed hawks are tertiary consumers, they will get 3000 kcal of energy.
Answer:d). Both have a carbon backbone where a ketose has a ketone group on the second carbon in the molecule, and an aldose has an aldehyde group at the end of the molecule.
Explanation: There are two families of monosaccharides: aldoses and ketoses.
The back-bones of common monosaccharides are unbleached carbon chains in which all the carbon atoms are linked by single bonds. When these monosaccharides are in an open chain form, one of the carbon atoms is double-bonded to an oxygen atom to form a carbonyl group.
When the carbonyl group has a hydrogen atom bonded to it, it is called an aldehyde group and when the carbonyl group is bonded to two carbon atoms, it is called a ketone group.
A Monosaccharide in which the aldehyde group is at the end of the carbon chain of the molecule is called an aldose while a monosaccharide in which the ketone group is on the second carbon atom of the molecule is called a ketose.
