| Life Systems - Habitats and Communities |
| 4s1 |
demonstrate an understanding of the concepts of habitat and community, and identify the factors that could affect habitats and communities of plants and animals; |
| 4s2 |
investigate the dependency of plants and animals on their habitat and the interrelationships of the plants and animals living in a specific habitat; |
| 4s3 |
describe ways in which humans can change habitats and the effects of these changes on the plants and animals within the habitats. |
| 4s5 |
classify organisms according to their role in a food chain (e.g., producer, consumer); |
| 4s7 |
describe structural adaptations of plants and animals that demonstrate a response of the living things to their environment (e.g., the height of a plant depends on the amount of sunlight the plant gets; many animals that live in the Arctic have white fur); |
| 4s8 |
recognize that animals and plants live in specific habitats because they are dependent on those habitats and have adapted to them (e.g., ducks live in marshes because they need marsh plants for food and shelter and water for movement); |
| 4s9 |
classify plants and animals that they have observed in local habitats according to similarities and differences (e.g., in shape, location). |
