3.6 - Ecosystems

The student will investigate and understand that ecosystems support a diversity of plants and animals that share limited resources. Key concepts include

a)  aquatic ecosystems;

  • describe major water-related ecosystems and examples of animals and plants that live in each  Bloom's Level: Understand
  • compare and contrast water-related and dry-land ecosystems.  Bloom's Level: Analyze
  • explain how animals and plants use resources in their ecosystem.   Bloom's LevelUnderstand

b)  terrestrial ecosystems;

  • describe major dry-land ecosystems and examples of animals and plants that live in each  Bloom's Level: Understand
  • compare and contrast water-related and dry-land ecosystems.  Bloom's Level: Analyze
  • explain how animals and plants use resources in their ecosystem  Bloom's Level: Understand

c)  populations and communities; and

  • distinguish between a population and a community.   Bloom's Level: Analyze
  • predict what would occur if a population in a specific ecosystem was to die.   Bloom's Level: Understand
  • analyze models or diagrams of different water-related ecosystems in order to describe the community of organisms each contains and interpret how the organisms use the resources in that ecosystem.   Bloom's Level: Analyze
  • analyze models or diagrams of different dry-land ecosystems in order to describe the community of organisms each contains and interpret how the organisms use the resources in that ecosystem. Bloom's Level:  Analyze

d)  the human role in conserving limited resources.

  • list ways that humans can help conserve limited resources.  Bloom's Level:  Knowledge

BIG IDEAS

Plants and animals share limited resources.


UNDERSTANDING THE STANDARD

  • Water-related ecosystems include those with fresh water or salt water. Examples include ponds, marshes, swamps, streams, rivers, and oceans.
  • Dry-land ecosystems include deserts, grasslands, rain forests, and forests.
  • There are distinct differences among pond, marshland, swamp, stream, river, ocean, desert, grassland, rainforest, and forest ecosystems.
  • A populationis a group of organisms of the same kind that lives in the same place. Examples of a population are a flock of swans in a pond, a school of fish in a river, and a herd of cattle in the grassland.
  • A community is all of the populations that live together in the same place. An example of a dry-land community would be a forest made up of trees, squirrels, worms, rabbits, and hawks. An example of a water-related community would be an ocean made up of fish, crabs, and seaweed.
  • Organisms compete for the limited resources in their specific ecosystem.
  • Humans need to help conserve limited resources.

ESSENTIALS

Essential Questions:

·  How do plants and animals compete for the same natural resources within their dry-land and/or water     ecosystem?

·  How can you describe the major water-related and dry-land related ecosystems?

·  How are water-related and dry-land ecosystems similar and different?

·  What is the difference between a population and a community?

·  How can humans help conserve limited resources?

In order to meet this standard, it is expected that students will

  • describe major water-related ecosystems and examples of animals and plants that live in each.
  • describe major dry-land ecosystems and examples of animals and plants that live in each.
  • compare and contrast water-related and dry-land ecosystems.
  • explain how animals and plants use resources in their ecosystem.
  • distinguish between a population and a community.
  • predict what would occur if a population in a specific ecosystem was to die.
  • analyze models or diagrams of different water-related ecosystems in order to describe the community of organisms each contains and interpret how the organisms use the resources in that ecosystem.
  • analyze models or diagrams of different dry-land ecosystems in order to describe the community of organisms each contains and interpret how the organisms use the resources in that ecosystem.
  • list ways that humans can help conserve limited resources.
