Interactions between species, including predation, competition, and symbiosis, drive evolutionary changes and shape the biodiversity of the habitat. Each transfer involves a loss of energy, typically as heat, which explains why food chains rarely exceed four or five levels.
Ecosystems Explained Energy Flow Pathways
Adaptation and Interaction Species within an ecosystem evolve specific adaptations to survive their environment. Abiotic factors are the non-living chemical and physical parts of the environment.
They break down dead organic material, returning essential nutrients to the soil. This energy is then transferred through a series of consumers, moving from herbivores to carnivores.
Ecosystems Explained Energy Flow Pathways
Organism Type Role Example Producer Creates energy from inorganic sources Grass, Trees, Algae Primary Consumer Eats producers Rabbit, Deer Secondary Consumer Eats primary consumers Fox, Frog Decomposer Breaks down dead matter Fungi, Bacteria Trophic Levels and Food Webs While food chains illustrate a linear path of energy, real-world ecosystems are more complex. How Energy Flows Through Systems Energy enters most ecosystems through photosynthesis, where plants and other producers convert sunlight into chemical energy.
