Answer:
An ecosystem consists of both biotic and abiotic factors. But what exactly are these factors? How do they impact an ecosystem, and do changes in abiotic and biotic factors change the ecosystem? An ecosystem depends on the interactions of the living and nonliving elements in the system.
Explanation:
Biotic Factors in an Ecosystem
In an ecosystem, biotic factors include all the living parts of the ecosystem. A healthy woodland ecosystem contains producers like grasses and trees, as well as consumers ranging from mice and rabbits to hawks and bears. The biotic components of an ecosystem also encompass decomposers like fungus and bacteria. A healthy aquatic ecosystem includes producers like algae and phytoplankton, consumers like zooplankton and fish, and decomposers like bacteria. Specific biotic categories include:
Plants: Most ecosystems depend on plants to perform photosynthesis, making food from water and carbon dioxide in the ecosystem. In ponds, lakes and the ocean, many of the plants are grasses, algae or tiny phytoplankton floating on or near the surface. Also in this category are the chemosynthetic bacteria that live at deep ocean vents, which form the base of that food chain.
