Plant & Animal Interdependence Week 9 Directions Prepare your desk for science. Use voice level 0 (no voice) to… Number notebook pages 26 to 50. Look at textbook pages 73 to 75. Think about what we will learn about this unit.

Targets & Warm Up Targets: Students will identify the basic characteristics of an ecosystem. Students will understand how the parts of an ecosystem interact. Warm Up: What does interdependence mean?

Interdependence People, animals, organizations or things depending on each another Dependence on each other or one another; mutual dependence Is there interdependence between… You and your parents? You and your teachers? Living things in nature?

Important words to know Organism: An individual living thing Species: A group of animals or plants that are similar and can produce young animals or plants

System A system is made of many parts that work together for a purpose

Ecosystem (pg. 79) All the living and nonliving things in an environment and the many ways they interact What are some examples of living things? What are some examples of nonliving things?

Living Parts Living parts: animals, plants, fungi, protists, and bacteria

Fungi, Protists, and Bacteria (pg. 11) Bacteria are the simplest of creatures that are considered alive. They are everywhere! Protists live in water and moist environments. Fungi are not plants because they cannot make their own food. Algae Mushrooms

Nonliving Parts Nonliving parts: air, water, soil, sunlight, climate, and landforms

Living or Nonliving?

Ecosystem vs. Biome Biomes are several ecosystems put together. Ecosystems vary in size and can be as small as a puddle or as large as a forest.

Habitat The area or place where an organism lives in an ecosystem The organism’s “address” Contains all the living and nonliving things that an organism needs

What is the difference between Habitat and Ecosystem? One ecosystem could contain many habitats, but not the other way around. An ecosystem is always larger than a habitat. A group of habitats make an ecosystem, but a group of ecosystems make a biome. One habitat contains one or few species, but one ecosystem contains a very large number of species.

Population All the members of one species that live within an area of an ecosystem

Community Different populations that interact with each other in the same area

Video Ecology Introduction Ecosystems, population, and community (3 minutes and 30 seconds)

Niche The specific role an organism has in its habitat Examples: The type of food an organism eats How an organism gets its food Which other species use the organism as food

What are the niches of this sunflower? Absorbing light, water and nutrients Providing shelter and food for other organisms Giving off oxygen into the atmosphere

What are the niches of… Squirrels collect acorns and bury them for winter. Honeybees gather nectar from flowers to make honey.

Can you use the words we have learned to describe this picture? ecosystem, living, nonliving, habitat, population, community, niche

Reflection questions What is the difference between a population and a community? What is the difference between a habitat and a niche?

Targets (Revisited) Students will identify the basic characteristics of an ecosystem. Students will understand how the parts of an ecosystem interact.
