Discover how energy flows through nature. Explore food chains in the forest, ocean, and savanna, learn what producers, herbivores, and apex predators do, and build your own food chains in practice games.
Plants make their own food through photosynthesis using sunlight, water, and carbon dioxide.
Energy flow, trophic levels, biomes, and tips for young ecologists.
A food chain shows how energy passes from one living thing to another. It starts with the Sun, which gives energy to plants, which are eaten by herbivores, which are then hunted by predators.
Producers (plants and algae) make their own food through photosynthesis. Primary consumers (herbivores) eat plants. Secondary consumers and apex predators hunt other animals. Decomposers recycle dead material back into the soil.
Explore three environments: a deciduous forest (grass to hawk), an open ocean (plankton to shark), and an African savanna (acacia to lion).
Practice features three interactive mini-games: ordering scrambled organisms from producer to apex predator, identifying trophic roles, and determining predator-prey relationships.
Ask learners what would happen if grass disappeared from a forest. Emphasize that all animals ultimately depend on plants and sunlight.
A food chain is a single, direct path of energy (grass to frog to hawk). In real nature, multiple overlapping food chains form a complex food web.

It is a free interactive science web tool designed for beginners to understand ecosystems, food chains, and energy flow across forest, ocean, and savanna habitats.
The Sun provides the raw radiant energy that green plants and algae use to create food through photosynthesis. Without sunlight, plants cannot grow and herbivores cannot survive.
An apex predator is an animal at the top of the food chain that has no natural predators in its ecosystem, such as a great white shark, eagle, or lion.
Decomposers like mushrooms, bacteria, and earthworms break down dead plants and animals into rich nutrients that return to the soil and water.
Practice mode offers three self-paced games: building chains in order from producer to apex predator, matching trophic roles, and selecting predators.

It is created for elementary students, homeschoolers, parents, and curious science beginners discovering biology and ecology.
This tool focuses on clear, linear food chains for early elementary learners. It does not simulate full multi-tier trophic pyramid biomass math or complex microbial food webs.
