About This Lesson
All the living and non-living components of an area that interact with each other for their survival form an ecosystem. Let's learn more about ecosystem through this video.

identifying and sorting examples of living and non-living things in the local environment.
Describe how plants and animals cause change in their environment.
Describe how environmental factors (e.g., soil composition, range of temperature, quantity and quality of light or water) in the ecosystem may affect a member organism’s ability to grow, reproduce, and thrive.
Describe ways various resources (e.g., air, water, plants, animals, soil) are utilized to meet the needs of a population.
Students know ecosystems can be characterized by their living and nonliving components.
Students know producers and consumers (herbivores, carnivores, omnivores, and decomposers) are related in food chains and food webs and may compete with each other for resources in an ecosystem.
Support an argument that plants get the materials they need for growth chiefly from air and water.
Support an argument that plants get the materials they need for growth chiefly from air and water.
describe how plants and animals, including humans, depend upon each other and the nonliving environment.
Plants require air, water, nutrients, and light in order to live and thrive.
Living things grow, take in nutrients, breathe, reproduce, eliminate waste, and die.
Support an argument that plants get the materials they need for growth chiefly from air and water.
Describe how the plants and animals in an ecosystem depend on nonliving resources.
Specify how a system can do things that none of its subsystems can do by themselves (e.g., a forest ecosystem can sustain itself, while the trees, soil, plant, and animal populations cannot).
Give examples to show how the plants and animals depend on one another for survival (e.g., worms decompose waste and return nutrients to the soil, which helps plants grow).
Compare the roles of producers, consumers, and decomposers in an ecosystem.
Apply knowledge of a plant or animal’s relationship to its ecosystem and to other plants and animals to predict whether and how a slow or rapid change in the ecosystem might affect the population of that plant or animal.
