There are differing levels of producers, consumers, and decomposers in the video.

Lisa holds a master’s degree in human relations and has taught at all levels.

Over the course of 10 years, she has taught high school science.They received their degrees from the medical school and the college.In Massachusetts, they are certified in secondary special education, biology, and physics.

Imagine a savanna with a circle of life.The grass is eaten by an animal.The animal is eaten by an animal.The cheetah dies, is eaten bybacteria, and the soil is returned to it’s original state.As the grass grows on the savannah, it uses these nutrients.The organisms have a purpose.There is a simple pattern of energy flow through organisms.Is there any other examples you can think of?

There are three main groups to consider when looking at the circle of life.The groups are made up of producers, consumers, and decomposers.The groups are based on how the organisms get food.In food chains and food webs, producers, consumers, and decomposers are dependent on one another for survival.

Producers make their own food.They don’t have to get energy from other organisms.They get their energy from the sun and use it to make food.It is possible that producers are also called autotrophs.Most producers are plants, but there are some small organisms that produce food.The beginning of a food chain is where producers are.Plants that grow on the African savanna are examples of producers.

Consumers can’t make food.They need to find food and eat it.Consumers may be called Heterotrophs.There are both primary and secondary consumers.The next link in the food chain is the primary consumers.These are people who eat plants.They don’t eat other animals.An example of a primary consumer on the African savanna would be a giraffe.

Secondary consumers follow primary consumers.Primary consumers eat secondary consumers.Secondary consumers can be omnivores.People who eat both meat and plants are called omnivores.Secondary consumers on the African savanna can include a lion who kills and eats the giraffe, or a human who does the same.

The last link in a food chain iscomposers.They may be called saprobes.composers eat decaying organic materialAn animal is eaten if it dies.If a tree loses a leaf, they eat it as well.It is possible to get rid of anything that is no longer alive by breaking it down and returning it to the soil.The cycle will begin again when producers use these nutrients.On the African savanna, there are examples of organisms that eat dead animals and a fallen tree.

Let’s look at it.There is a pattern of energy flow through organisms.Producers begin this cycle by making their own food.Primary consumers can’t produce their own food so they eat the producers.Primary consumers only eat plants.Like lions, secondary consumers are meat eaters.The primary consumers are eaten by them.The primary consumer is eaten when it dies.The circle of life will begin again when this returns to the soil.

The process by which producers get their energy from the sun is called photosynthesis.

The link to producers in a simple food chain is called primary consumers.

Primary consumers are the link to secondary consumers in a food chain.

Decomposers are a circular link between consumers and producers in a simple food chain.

In this lesson, students will imagine a situation in which one of the three trophic levels goes extinct.Humans are changing natural ecosystems faster than ever before, and in this assignment, we will play that scenario through to the end.In the writing, students will imagine what will happen if there is a disaster.

Students might imagine a world without people.They would show how trash and decaying organic matter would build up and cause producers to die.Consumers would have no food and the global economy would collapse.

Imagine what life would be like without one of the trophic levels.The consequences of removing a trophic level will be imagined in your piece.Direct effects on specific species should be included in the descriptive language.Your final product can be any of the following: essay, comic, slideshow, poster, or any other creative medium.Check out the criteria for success below to make sure your piece has all of the requirements.
