A community structure is define by the diverse organism present and the various number of species.
A community requires both biotic and abiotic factor to form a good structure.
Base population is needed - this are the primary producer, that transfer energy to other organism in the environment. The produce their food themselves.
Consumers - consumers feeds on producers, herbivores animals feeds on producer/plant while carnivores feeds on herbivores. Energy is then transfer when they chemical reaction takes place via the food comes
Decomposer - They act on the dead and remains of plant and animal. They help release nutrient back into the soil. Example of decomposer is earth worm.
It consists of the alveolar wall, the capillary wall, and their basement membranes.
If all other resources are in adequate supply, then the light intensity will increase the rate of photosynthesis. To balance it out, other things then usually start becoming short in supply, so things often don't change.
The oxygen molecules moves through the nostrils, pharynx, trachea, bronchus, smaller and smaller branches of the bronchial tree, and then into the alveolus.
