Food Chain Definition Types Examples and Diagram Biology Diagrams In a grassland ecosystem, a grasshopper might eat grass, a producer. The grasshopper might get eaten by a rat, which in turn is consumed by a snake. Finally, a hawk—an apex predator—swoops down and snatches up the snake. Food Chain Diagram. Trophic Levels. Trophic level refers to the sequential stages in a food chain, starting with A Grassland Food Chain. The first step of the food chain (sometimes referred to as the bottom of the food chain) is usually made up of producers - organisms that can make their own food. In a The food chains in an ecosystem intertwine to form a food web. This interactive shows a simplified grassland food web. Each set of arrows links the organisms in one food chain. Note that most organisms in a food web belong to multiple food chains.
This is an African Savanna Food Web.See if you can identify all the parts of the food web that make this a functioning, healthy ecosystem. Look for: The Producers - the trees, shrubs and grass.. The Primary Consumers - the zebras and elephants.. The Secondary Consumers - the cheetah, hyena.. The Scavengers - the termites, vultures and hyena.. The Decomposers or Detritivores - mushrooms Learn how grass, insects, frogs, snakes, coyotes, vultures and hawks form a food chain in a grassland ecosystem. See a diagram and examples of each tropic level and how they interact.
Grassland Food Chain & Food Web Biology Diagrams
Now let's have a four-step grassland food chain example. In a grassland ecosystem grass is eaten up by insects; these insects are eaten by the frogs and lastly, these frogs are consumed by the birds. This food chain can be represented as: Grass → Insects → Frog → Snake → Bird In a grassland food chain, grass grows as the producer.
As you move up the food chain, each level receives only about 10% of the energy from the level below it. This energy loss limits most food chains to 3-4 trophic levels. Savanna food chains follow these same principles as energy transfers between trophic levels, beginning with producers. Savanna Food Chain Trophic Levels and Components Explained A food chain in a grassland ecosystem may consist of grasses and other plants, grasshoppers, frogs, snakes and hawks (Figure 8.3). In a freshwater aquatic ecosystem like a pond, the organisms in the food chain include algae, small animals, insects and their larvae, small fish, big fish and a fish-eating bird or animal (Figure 8.4). A food chain
