As autotrophs are the foundation of all ecosystems on Earth, this type of food chain is used by most ecosystems. This wonderful collection of Food Web Posters explores three distinct ecosystems. The food webs covered are: Set up a food web on your classroom floor using painter's tape and printed pictures, then allow students to walk the web to see how organisms interconnect. Detritivores are organisms that feed on dead matter. These include fungi, bacteria, protozoans, and so on.

Spend more time lesson- doing and less time lesson- planning when you grab these activities and teaching resources too! Allow students to explore magazines — cutting out images of the various levels of the food chain — then create their own circle of life on a paper plate. Humans are not at the top of the food chain because of their wide variety of diets, including both plant-based foods and animals from various trophic levels. Animals at the apex mainly consume other carnivores, and humans can consume plants, herbivores, or carnivores. Moreover, ecosystem is complex and interconnected, involving numerous species with energy and nutrient flows. While humans have significant impacts on ecosystems, their role is influenced by cultural, ecological, and technological factors, making their position in the food chain complex and multifaceted. Importance of Food Chain and Food Web Moved into a science classroom this year and just getting up to speed? The expert science teachers on the Teach Starter team have put together the answers to some of teachers' most common questions! What Is the Difference Between Food Web and Food Chain? Food Chain diagram | Image credit: Ecology of ecosystems: Figure 3 by OpenStax College, Biology, CC BY 4.0In a forest ecosystem, plants and trees are the ones that make things. A deer eats plants, while a carnivore like a tiger eats a deer. Organisms that eat other organisms are called consumers. The first organism in a food chain is the only one that doesn’t eat.

Now we can look at how energy and nutrients move through a community of living things. Let’s start by looking at a food chain to see a few examples of who eats who. This resource was created by Madison Evans , a teacher in North Carolina and Teach Starter Collaborator.

Species in a food chain are interdependent. This interdependence helps to maintain the population of any one species in the ecosystem.
