Ecosystem Dynamics: Food Chains, Food Webs, and Symbiotic Relationships

The two fundamental concepts that govern the interactions in an ecosystem are food chains, food webs, and symbiotic relationships.

Producers, such as plants or algae, harness energy from the sun through photosynthesis and form the base of the food chain.

While food chains provide a simplistic view of energy flow, ecosystems are rarely so linear. In reality, organisms are interconnected through intricate networks known as food webs, which illustrate the complex relationships between various species within an ecosystem.
