- A food web is a complex network of interconnected food chains that shows how energy and nutrients flow through an ecosystem by illustrating what organisms eat and are eaten by.
- If the snake population decreases, the populations of its prey (like mice, frogs, and birds) would likely increase due to reduced predation, while the populations of its predators (like hawks and owls) might decrease due to less available food.
- An ecosystem is considered to be in equilibrium when the populations of all organisms remain relatively stable over time, with energy and nutrient flows balanced and no major disruptions to the food web.
- As we move up from one step to another in a food chain or web, energy decreases significantly at each trophic level because most energy is lost as heat during metabolic processes, with only about 10% typically transferred to the next level.
- A food chain is a linear sequence that shows how energy is transferred from one organism to another, starting with a producer and ending with a top predator.
- The producer in the food chain is grass.
