Describe the energy flow in the salt marshes on Port Isobel.
1) Describe energy forms/sources and transformations.
2) Relate energy flow within the system to abundance of species, both plants and
animals, and
diversity of species, both plants and animals. Abundance
refers to how many or how much
there is and diversity refers how many different kinds. Comment on the dominant
(the most
abundant) plant and animal.
3) The goal of a species is to survive to the next generation, whether the
organism is a plant or
animal.
The goal of an ecosystem is to perpetuate itself-no outside
human influences.
Consider the plants and animals you have chosen to address in your essay.
Evaluate how biologically successful (will they survive the next generations) and how
sustainable (able to perpetuate
itself) the saltmarsh ecosystem is.
