Fourth Grade Science: Interdependence with living and nonliving things
22
How are resources shared among living organisms in a specific ecosystem or habitat?
Introduction
Introduction
Hello! My name is Noah Young and I will be presenting a fourth grade learning objective for science. The objective is "Interdependence among living and nonliving components
creates a balance in the cycle of resources (an ecosystem)".
What are living components in an environment?
Living vs. Nonliving
A living organism is anything that can be considered alive. For example, plants, animals, and bacteria. Anything other than these are called nonliving organisms. For example, the atmosphere, dirt, and water
Can you name the living and nonliving organisms in this picture?
Example
Living organisms depend on nonliving organisms to survive
How they interact
For example, a mouse might burrow underground for shelter. Another example is how the sun gives plants energy to grow, and then those plants are eaten by animals and converted to energy
With your shoulder partner, come up with at least five other examples of how living and nonliving organisms interact
Activity
What makes up an ecosystem?
Ecosystems
Ecosystems are a community of interacting living and nonliving organisms and the environment they surround. For example, a forest ecosystem would likely consist of trees, deer, rabbits, fungi, worms, sun rays, soil, the atmosphere surrounding it, etc.

Brainstorm a list of things inside of school that are living and nonliving. Then, think of how they interact with each other. This will be your school ecosystem
School Ecosystem
What would happen if you removed those resources?
Resources in an ecosystem
Lets go back to the mouse example. If the soil wasn't there to burrow, the mouse wouldn't have shelter from predators or a place to store their food. The soil also wouldn't get the carbon dioxide from the mouse that it needs to give nutrients to the plants above ground. Without carbon dioxide, the plants would die. Everything in an ecosystems interacts and depends on each other for survival.
