Study Notes
Energy Roles of Organisms
- Producers obtain energy directly from sunlight or inorganic substances, forming the base of the food chain.
- Consumers are organisms that gain energy by feeding on other living beings.
Categories of Consumers
- Herbivores exclusively consume plants, playing a crucial role in energy transfer from producers to higher trophic levels.
- Omnivores have a varied diet that includes both plants and animals, allowing them to occupy multiple roles in the food web.
- Carnivores are meat-eaters that primarily consume other animals, influencing predator-prey dynamics.
- Scavengers specifically consume dead organisms, aiding in decomposition and nutrient cycling.
Decomposers
- Decomposers break down organic waste and dead organisms, returning essential raw materials to the ecosystem and facilitating nutrient recycling.
Food Structures
- A food chain outlines a linear sequence depicting how energy is transferred through different organisms, highlighting predator-prey relationships.
- A food web illustrates the interconnected feeding relationships among various organisms in an ecosystem, showcasing the complexity of energy transfer.
Energy Flow
- An energy pyramid visually represents the distribution of energy across different feeding levels in an ecosystem, indicating that energy decreases at each successive trophic level.
