The main difference between primary secondary and tertiary consumers is that primary consumers are the herbivores that feed on plants, and secondary consumers can be either carnivores, which prey on other animals, or omnivores, which feed on both animals and plants, whereas tertiary consumers are the apex predators that feed on both secondary and primary consumers. Rabbits, consuming grass are an example of primary consumers; snakes, consuming rabbits are an example of secondary consumers while owls, consuming snakes are an example of tertiary consumers.
Hi everyone, my name is neetu jacob I Am a tutor at lido and welcome you all to the lido learning here we have a question from the chapter Echo System so the question goes like this: differentiate among primary secondary and tertiary consumers give an example of each in a food chain.

Reproduction in Humans 4. This activity requires a large open area. In a class of 25 to 40 students, choose three to five to be predators and seven to ten to be plant-eaters.
The remainder will be plants. This represents a balanced system where plants are more plentiful than plant-eaters, plant-eaters more plentiful than predators, and predators are the least plentiful. The students can select which plant-eaters and predators will be in their groups.
Each group selects hand-signals that will differentiate them from the other groups. Example: the plants may want to hold their hands out to their sides to represent leaves, the plant-eaters oryx may hold their hands on the heads to represent horns, and the predators lions may hold their hands up like paws with the claws showing.
The predators try to tag the plant-eaters who try to tag the plants. Since predators decompose when they die and become fertilizer, the plants try to tag the predators. Once you are tagged, you turn into whatever tagged you.
After a period of time, stop the game to see how many plants, plant-eaters, and predators are left. Play should resume but should be stopped a few times before the end to determine what has happened and why.
After playing a few rounds of the game, select one of the plants to re-enter the game as a human. The rules for the human are different: the human can tag anyone, but no one can tag the human. Each time the human tags someone, that player becomes another human. See how long it takes before all players have become changed into humans. Discuss the changes and relationships that the game illustrates. Some questions for discussion might include:. Sign up for our Interactive Classroom - Coming Soon!
Teaching Standards. Objectives Students will learn about food chains , pyramids, and food webs. Background A food chain shows how each living thing gets its food. Food chains can also be represented in different forms such as this pyramid. Materials Food Chains Enough strips of colored paper so that each student has four, one on which to draw the sun, one on which to draw a producer, one on which to draw a primary consumer and one on which to draw a secondary consumer. Food Web Blank cards Colored pencils Yarn.
Vocabulary Carnivore: an organism that eats mostly meat Consumer: an organism, usually an animal, that feeds on plants or other animals Food chain: a sequence of organisms arranged in such a way that each feeds on the organism below it in the chain and serves as a source of food for the organism above Food web: all the connected or linked food chains within an ecological community Herbivore: an organism that eats mostly plants Predator: an animal that lives by killing and eating other animals Producer: an organism, usually a plant, that converts sunlight energy into living material; usually the first step on the food chain or food web or first trophic level of a food pyramid.
Preparation Cut enough strips of paper so that each student will have four. Food Webs Note: This activity can be added for older students. Discussion All living things need energy to stay alive.
Possible Questions Do you know why there are more herbivores than carnivores? What if one animal from the food chain disappeared? What about one level of the food chain? How do humans fit in the food chain? An organism like a mouse might play two roles, eating insects on occasion making it a secondary consumer , but also dining directly on plants making it a primary consumer.
A food web of who eats who in the southwest American desert biome might look something like this:. Keystone Species : In some food webs, there is one critical " keystone species " upon which the entire system depends. In the same way that an arch collapses when the keystone is removed, an entire food chain can collapse if there is a decline in a keystone species. Often, the keystone species is a predator that keeps the herbivores in check, and prevents them from overconsuming the plants, leading to a massive die off.
When we remove top predators like grizzly bears, orca whales, or wolves , for example, there is evidence that it affects not just the prey species, but even the physical environment.
Apex Predators : These species are at the top of the food chain and the healthy adults have no natural predators. The young and old may in some cases be preyed upon, but they typically succumb to disease, hunger, the effects of aging, or some combination of them.
The also suffer from competition with humans, who often eliminate the top predators in order to have exclusive access to the prey species, or through habitat destruction, which is an indirect form of competition.
Decomposers : When organisms die, they are sometimes eaten by scavengers but the remaining tissues are broken down by fungi and bacteria. In this way, the nutrients that were part of the body are returned to the bottom of the trophic pyramid. Bioaccumulation : In addition to being less energy efficient, eating higher up the food chain has its risks.
