7. In the space below, construct an ecological pyramid for your ecosystem. Include at least nine organisms in your energy pyramid. Label each level of the pyramid with the correct trophic level. Label each level of the pyramid with the correct type of producer or consumer. Assume the lowest level of the pyramid has 100,000 units of energy. Label the units of energy that will be transferred up to the remaining levels of the pyramid.Ponds are a type of freshwater ecosystem that has shallow and slow-moving water (is lentic), and, because it's shallow, light can reach the bottom of it.Some organisms that we can find living in a pond are the following:Water liliesFrogsTurtlesFishGeeseDragonfliesAlgaeCyanobacteriaDucksWater snailDuck potatoEarthwormsMosquitosPond skaterNewtsMosquito fern/fairy mossDuckweedsWatersnakeSalamandersWater beetle

Sagot :

A ecological pyramid can be made of three different types of data, like the number, biomass, and energy of an ecosystem. In the question is asked for one pyramid of energy. The structure of a pyramid of energy is based on each trophic level of the ecosystem (producers and consumers).

Step 1. Write down the organisms living in the ecosystem.

Producers: Water lilies, Algae, Cyanobacteria, Mosquito fern/fairy moss, Duckweeds, Duck potato;

Primary consumers: Dragonflies, Turtles, Water snail, Earthworms, Pond skater, Newts, Water beetle;

Secundary consumers: Frogs, Mosquitos, Turtles, Fish, Watersnakes, Salamanders;

Terciary consumers: Ducks, Fish, Geese.

Step 2. Pyramid assembly.

It's a common fact between the ecologists that the amount of energy that is passed from trophic levels is about 10% from the previous level. Therefore the energy in the pyramid model of the question must have the numbers presented in the drawing.
