Large predators are found at higher trophic levels, what does this mean in terms of energy loss ?
VARVARA [1.3K]

Large predators are found at higher trophic levels because specialized bodies are needed to extract the small energy that gets to them.

The energy that gets to successive trophic levels decreases progressively because much of it is lost as heat. This means that a small percentage of the energy from the producers that form the bases of trophic levels to the predators that are somewhat at the top of trophic levels.

With big body size, the bodies of predators are organized into systems that work together to efficiently extract the small energy that gets to them from immediate lower trophic level.

More on the energy from trophic levels can be found here: brainly.com/question/13375401?

PLEASE HELP! Emma prepared two glasses of water at two different temperatures. She added a spoonful of table salt to the cold wa
Sergio039 [100]

Answer:

The correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.

Explanation:

For the majority of the solids dissolved in water, the solubility increases with temperature increments. Higher temperatures accompany the increase in kinetic energy permits the solvent particles to more adequately break apart the solute atoms that shows intermolecular attractions.

So if glass one dissolves the salt faster than glass two then it is clear that glass one has more temperature than glass two that takes more time to dissolve the rock salt.

Thus, the correct answer is - option B. No, the temperature in glass #2 is lower, which makes salt less soluble in water.

Cancer is due to a mutation with in a gene that regulates cell growth. Some of these mutations are random, but some can be cause
Katarina [22]

Answer:

These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.
