Energy Flow in the Ecosystem
They belong under the level of producers because they recycle non-living matter making it an available form of nutrition for plants.
What are decomposers and detritivores?
A diminished population of secondary consumers creates a food shortage.
What is a density dependent limiting factor.

Who is Norval Morrisseau?
Why did the penguins go for the anchovies and leave the shrimp even though they were running low on time and energy?

A tornado wipes out all of the trees where a certain type of bird lives.
What is a density independent limiting factor in an ecosystem?
How does 'Androgyny' represent man's place in the ecosystem?
Man's place in the ecosystem is equally important as all other biotic and abiotic elements.

Give an example of a biotic limiting factor.
What is the number if available producers/food.
The name of the insectivorous bird found at the (our) beach which is on the soon-to-be-engangered list?
What is the Least Bittern
Why do pioneer organisms get diminished during the process of succession? Give an example.
As new biotic elements appear in the ecosystem, they take resources from those which were there before. When tall leafy plants appear, they take sun and water from the grasses that preceded them and the grass becomes less abundant.
The position that decomposers, or producers, or predators, or herbivores etc. occupy in a food chain.
What is a trophic level?
