The levels of the diagram are labeled with percentages. What do the percentages represent?

The amount of energy

Explanation:

The percentage represents the amount of energy at each trophic level of the food chain/web.

A trophic level represents a hierarchical level in a food chain or food web in an ecosystem with each level consisting of organisms that share the same function and nutritional relationship to energy source.

The amount of energy in each trophic level decreases as we move up the food chain/web due to a loss to the environment as heat.

In the image, the first level represents the primary producer that are responsible for fixing energy directly from the sun. Hence, they posses 100% of the energy in the food web.

The second level represents the first-level consumers of primary producers. The amount of energy that gets to these consumers has reduced from 100% to 10%, meaning that 90% has been lost as heat to the environment.

The third level represents the second-level consumers. That is, those that directly feed on the first-level consumers. The amount of energy they derive has also reduced from 10% to 1% while in the third-level consumers, the amount of energy derived has reduced to 0.1%.

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
