ANSWER FOR 44 POINTS!!!! Also please answer it like don’t just put random stuff I actually need help here <3


1. A unit used to measure energy is the kcal.

a. What is the source of all
energy in the pyramid?

b. How much energy does this source provide to a square meter of the Earth per year? (Be sure your
answer includes units.)

2. The arrows represent the energy available to the next level of the pyramid.

a. What percentage of the source energy form question 1 is absorbed by the oak leaves? Divide oak levar got by the total sunlight hitting the earth’s surface.

b. By what process do the oak leaves harness this energy?

3. Describe how the consumers in one level of the pyramid obtain energy from the organisms at the previous level of the pyramid.

a. How much energy per year do caterpillars obtain from eating the leaves in a square meter of the oak tree?

b. What percentages the energy that was originally by the oak leaves is passed in to the caterpillars? Divide ye hat the caterpillars got by wag at leaves got.

c. What percentage of the energy absorbed by the oak leaves is not passed on to the caterpillars?

4. Calculate the percentage of the nervy that is transferred from one level of the pyramid to another for all of the levels?

a. Oak leaves to caterpillars (see question 3b)

b. Caterpillars to blue jays.

c. Blue jays to hawk.

5. Calculate the average percentage of energy that is transferred from one level to another using you answers in question 5. Note that this average percentage transfer is similar for many different types of energy pyramid in nature.

6. Explain why an energy pyramid in any ecosystem typically is limited to four or five levels only.

3,190,000 kcals

Label the pyramid levels in Model 1 with the following: primary producers, primary consumers, secondary consumers, and tertiary consumers

Oak tree leaves are the primary producers

Caterpillars are the primary consumers

Blue Jays are the secondary consumers

Hawks are the tertiary consumers

What percentage of the source energy from question 1a is absorbed by the oak leaves in Model 1?

8 %

By what process do the oak leaves harness this energy?

photosynthesis

Describe how the consumers in one level of the pyramid obtain energy from the organisms at the previous level of the pyramid

By consuming them

How much energy per year do the caterpillars in Model 1 obtain from eating the leaves in a square meter of the oak tree?

4,000 kcal

What percentage of the energy that was originally absorbed by the oak tree leaves is passed on to the caterpillars

13.5%

What percentage of the energy absorbed by the oak leaves is not passed on to the caterpillars

84.3%

With your group, list at least three possible uses and/or products of the energy absorbed by the oak leaves that did not contribute to the production of biomass.

Photosynthesis, heat, leaves changing colors
