Question

1. represent data build an energy pyramid using the data in the table.

species\tenergy (joules)
a\t4,982,000
b\t5200
c\t500,738
d\t47,033

1. identify in your model, label each species with its ecological role in the ecosystem.

Explanation:

Step1: Understand energy pyramid concept

In an energy pyramid, energy decreases from lower to higher trophic levels. Species with more energy are at lower levels.

Step2: Order species by energy

From highest to lowest energy: A (4,982,000 joules), C (500,738 joules), D (47,033 joules), B (5200 joules).

Step3: Build energy pyramid

Place A at the bottom - likely a producer as it has the most energy. Then C, D, and B successively higher up.

Step4: Identify ecological roles

Producers (like plants) capture energy from the sun and are at the base of the energy pyramid. Consumers eat other organisms. Since A has the most energy, it could be a producer. C, D, and B are likely consumers with B being a top - level consumer as it has the least energy.

Answer:

Energy pyramid: Place species A at the bottom (producer), then C, D, and B successively higher up. B is likely a top - level consumer, C and D are intermediate consumers.
