🌳 Did You Know? In the vast savannahs of East Africa, an elephant's favorite snack is the Senegalia mellifera tree. Now, imagine if there were tiny creatures munching on this tree, which were then eaten by some larger ones, and the chain continues until you reach the elephant. Cool, right? Let's dive into how these food chains work!

• Food chains show how energy flows in an ecosystem.
• Each stage in a food chain represents a trophic level.
• As we move up the trophic levels, energy is lost.

🍀 Example: Let's go on an underwater adventure!

• Bluefin tuna 🐟 in the North Atlantic munch on species that are either secondary or tertiary consumers.
• Although killer whales (orcas) sometimes snack on Bluefin tuna, they prefer a diet from the lower trophic levels.
• Orcas = Apex Predators 🐋 (Meaning? Top of the food pyramid! No one dares to eat them.)

• We might think that food chains could go on and on. 🔄 But here's the catch: at every trophic level, a LOT of energy gets lost.
• So, after a point, there isn't enough energy left to support another level. It's like trying to power a whole city with a single AA battery - not happening!

🥇 Golden Rule: Energy decreases as you move up the food chain.

🍝 Real-World Fun Fact: A Peregrine falcon 🦅 might seem pretty high up on the food chain, but it needs a territory bigger than 100km² just to find enough food! Imagine having to roam an area equivalent to over 14,000 soccer fields just for your daily burger!
