Building an Aquatic Ecosystem

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

A 1st grade class was planning to build a simple ecosystem in a jar, and add water, algae, and small aquatic animals that eat algae and then weigh their algae and the animals at the end of the year. If they were to compare the total weight of all the algae and the combined weight of all the animals, which will weigh more? Explain this using terms of energy and nutrients. What observations and inferences would be used to answer this?

Solution Preview

There are some assumptions that go into this question that I will address first, and then I will give some conclusions. The first assumption is that the ecosystem in the jar is balanced at the beginning of the experiment. That means that the jar is not packed with aquatic animals, nor is it packed with algae. The second assumption is that the jar is exposed to adequate ...

The Industrial Revolution & Biogeochemical Cycles

Please help me wiith these questions:

1. Revolutionary changes in human culture have greatly changed the relationship between humans and the environment. How have the Neolithic and Industrial Revolution impacted the natural environment, and what is meant by the Environmental Revolution?

2. The recycling of elements is another vital functional process occurring in all ecosystems. Describe the biogeochemical cycles for carbon, phosphorous, and nitrogen. How have humans impacted these three cycles?

3. The goods and services performed by natural ecosystems are essential to human survival. What is their overall value, and of what significance is it to measure this value?
