Answer:

It decreases by a factor of about 90%. I just did it

Explanation:

Only about 10% of the energy makes it from one level of an energy pyramid to the next. 90% of the energy is used for metabolism,etc.

The correct answer is - D) It decreases by a factor of about 10%.

In the energy pyramid for an ecosystem, the energy levels are consistent throughout the food chain, thus the pyramid shape of it. The organisms that are at the bottom of the pyramid are the ones that gain 100% energy, and those are the producers. As they are consumed, they give energy to another organism, bu that organism gets a bit less, by approximately 10%. The 10% decline in the energy transfer as we go up the hierarchy of the food chain continues, so the organisms that are at the top of the food chain actually gain much less energy than the ones on the bottom of the pyramid. That results in those organisms that are at the top of the pyramid to have to consume much larger amounts of food in order to survive, while the ones closer to the bottom need to consume much less.

Explain what takes place in each step of the diagram
Andrei [34K]

The given image is showing the interaction of the enzyme and its substrate.

In the first part of the image, the enzyme and substrate are not bind together. They are present in close proximity. The enzyme shown in the picture have a site for the attachment of the substrates.

In the next picture, the interaction of the enzyme and the substrate has occurred, which resulted in the formation of the enzyme substrate complex. Hence, the given picture shows the interaction of an enzyme with the substrates.

Choose all the answers that apply. Erosion is caused by _____. wind water ice gravity
bezimeni [28]
Water erosion is usually what people think of, but ice, wind and gravity can also cause erosion.

Water erosion is usually along rivers. As the water moves quickly by it rubs on the rock and dirt, causing rivers to slowly get wider.

Ice erosion is caused by glaciers. Sometimes it's a glacier rubbing against land, and there's a lake that was made by a glacier making it's way onto land and then melting.

Wind erosion is a big problem in fields and large open plains with loose dirt. The wind just blows all the dirt away.

Gravity can cause erosion and cliffs. Sometimes along a mountain or cliff the rock won't be able to hold itself up anymore, and gravity will pull it down.

Your answer would be all of them. Wind, water, ice, and gravity.
