Biotic factors in an ecosystem are the living components that influence the structure and functioning of that ecosystem. They include all the organisms that interact with each other and with their environment. Here are a few examples of biotic factors:
1. **Producers (Autotrophs)**: These are organisms, such as plants and algae, that create their own food through photosynthesis or chemosynthesis. They form the base of the food web.
2. **Consumers (Heterotrophs)**: These include herbivores (primary consumers), carnivores (secondary and tertiary consumers), and omnivores that depend on other organisms for their energy and nutrients. Examples include deer (herbivores), wolves (carnivores), and humans (omnivores).
3. **Decomposers**: These organisms, such as fungi and bacteria, break down dead organic matter and waste, recycling nutrients back into the ecosystem, which is essential for soil health and nutrient cycling.
4. **Symbiotic Relationships**: Interactions between different species, such as mutualism (both species benefit, like bees and flowers), commensalism (one benefits while the other is not significantly affected, like barnacles on whales), and parasitism (one benefits at the expense of the other, like ticks on mammals).
These biotic factors interact with abiotic factors (like temperature, water, and soil) to shape the ecosystem.
