Like all plants, grasses are producers. Remember that a producer is a living thing that makes its own food.

Food Chain The primary consumers are those that feed on producers, while secondary consumers eat primary consumers. In grasslands, for example, grass acts as the producer, while mice that eat grass are the primary consumers.

For example, rabbits and deer are primary consumers because they eat grass. The next level is secondary consumers. Tertiary consumers eat secondary consumers to get their energy. For example, owls are tertiary consumers because they eat snakes.

Grasshoppers are eaten by birds, spiders, snakes, rodents and insects. In Mexico and Africa, grasshoppers are eaten by humans for their high protein content. Grasshoppers eat cereal crops, grass and leaves, but some species of grasshoppers are omnivorous.

A food chain is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species. eg. Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers — an example is a rabbit that eats grass.

A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected. eg: A hawk might also eat a mouse, a squirrel, a frog or some other animal.

The definition of a food chain is a system where a small animal is the food for a larger animal which, in turn, is the food for an even larger animal. The sequence of the transfer of food energy from one organism to another in an ecological community.

Once students understand, have them draw the sun, a producer, a primary consumer, a secondary consumer, and a tertiary consumer on each of their four strips. These should then be interlocked and glued together to make a chain of species in which one eats the other.

The process of transfer of energy from producers through a series of organisms, i.e., from primary consumers to secondary consumers and from secondary consumers to tertiary consumers by process of eating and being eaten constitute a food chain. The correct food chain is phytoplankton >> zooplankton >> fish.

Humans are said to be at the top of the food chain because they eat plants and animals of all kinds but are not eaten consistently by any animals. The human food chain starts with plants. Plants eaten by humans are called fruits and vegetables, and when they eat these plants, humans are primary consumers.

Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.

There are two types of autotrophs: photoautotrophs and chemoautotrophs. Photoautotrophs get their energy from sunlight and convert it into usable energy (sugar). This process is called photosynthesis.

A food chain is a linear diagram showing how energy moves through an ecosystem. It shows only one pathway out of the many possibilities in a specific ecosystem.

Food Chain. A food chain shows you how one organism eats another and transfers its energy. For example, a zebra eats grass, and the zebra is eaten by the lion.

Cows are in a simple food chain that begins with grass and ends with humans.
