Title: What%20Are%20Ecosystems?


1
What Are Ecosystems?
  • Objectives
  • Compare different climates.
  • Describe how organisms interact in ecosystems.
  • Explain how climate affects ecosystem diversity.
  • Main Idea and Details
  • Look for details about ecosystems.

2
Vocabulary
  • Ecosystem
  • Population
  • Community
  • Habitat
  • Niche
  • Diversity

3
Science Background
  • Do plants and animals interact in ecosystems?
  • How do you think plants and animals interact with
    each other in nature?
  • Scientists Explain
  • There are many plant-animal interactions in
    nature. Animals eat plats to get energy and
    nutrients. Plants serve as habitats for insects,
    small animals, and birds. Plans (and algae) also
    release oxygen into the air as a byproduct of
    photosynthesis. People and other animals need
    oxygen to live. Plants use it in the process of
    respiration.

  • Consumer
  • Producer

5
Vocabulary Power
  • Do the worksheet on your ownyou have 7 minutes
  • READY..
  • SET.
  • GO!!!!!!

6
Vocabulary Power
  • Check your answers with the people in your group.
  • Now lets check it as a class

7
Vocabulary Power
  1. A struggle for limited resources
  2. Organisms that live on another organism
  3. Groups of organisms of the same species living
    together in an ecosystem.
  4. Consumer

Great Job!!!

150 - Ecosystems
  • Science Concepts
  • -What an ecosystem is and how organisms interact
    in ecosystems.
  • -What factors affect diversity.

150 - Ecosystems
3
  • What are the biotic parts (living) of this
    forest?
  • They are the trees, shrubs, flowers, deer,
    insects, fallen leaves, skunks and birds.

10
150 - Ecosystems
4
  • Would the abiotic (nonliving) parts of the
    ecosystem you see in the illustrations be similar
    or different from the ones you would see in
    another ecosystem, such as a desert?
  • The same categories the same (soil, plants, and
    so on), would be present but the types of rocks,
    soil, air quality, and so on would be different.

11
150 - Ecosystems
5
  • Main Idea and Details
  • What are the biotic and abiotic parts of an
    ecosystem?
  • The biotic parts of an ecosystem are the living
    parts the abiotic parts of an ecosystem are the
    nonliving parts.

12
150 - Ecosystems
  • Vocabulary
  • 151 Ecosystem
  • an area where organisms interact with one another
    as well as with the nonliving parts of the
    environment.

13
Main Idea and Supporting Details
  • Subheading Ecosystems
  • Each organism in an ecosystem interacts with
    other organisms.
  • biotic parts are the living parts of an
    ecosystem.
  • abiotic parts are the nonliving parts of an
    ecosystem.
  • an ecosystems biotic parts interact with each
    other.
  • an ecosystems abiotic parts help determine what
    lives in it.

14
152 A Place to Live
11
  • Which has a better chance of survival if
    conditions change an organism with a broad niche
    or one with a narrow niche?
  • Broad, because it can live in a wider variety of
    conditions

15
12
152 A Place to Live
  • Main Idea and Details
  • How are a population and a community related in
    an ecosystem?
  • A population is a group of organisms of the same
    species living in an ecosystem. A community is
    all the populations of an ecosystem.

16
152 A Place to Live
  • Vocabulary
  • 152 Population
  • A group of organisms of the same species living
    together in an ecosystem.
  • 152 Community
  • All populations living in an ecosystem.
  • 153 Habitat
  • The part of the ecosystem in which the organism
    lives.
  • 153 Niche
  • The organisms role in an ecosystem.

17
Main Idea and Supporting Details
  • B. Subheading A Place to Live
  • A population is a group of organisms of the same
    species living together in an ecosystem
  • All of the populations in an ecosystem make up a
    community
  • Cacti have connections with many animals of the
    desert ecosystem
  • Two populations with similar needs can share a
    habitat
  • Two populations cant share the same niche.

18
13
154 Diversity
  • How can the extinction of one species decrease an
    ecosystems diversity over time?
  • Removal of one could eliminate others that depend
    on it for food.

19
15
154 Diversity
  • Main Idea and Details
  • Why are climate and location the two most
    important factors in determining ecosystem
    diversity?
  • In general, ecosystems closer to the equator are
    warmer and have more species and so are more
    diverse. Ecosystems closer to the poles are
    colder and have fewer species and so are less
    diverse.

20
154 - Diversity
  • Vocabulary
  • 154 Diversity
  • The variety of species in an ecosystem.

21
154 Insta-Lab
  • Marble Diversity
  • I will pass around a jar of marbles.
  • Reach into the jar, and pull out a handful of
    marbles.
  • Sort the marbles by type.
  • How many types do you have?
  • Compare your results with those of other tables.
  • Who has the most diverse handful of marbles?

22
Main Idea and Supporting Details
  • C. Subheading Diversity
  • Diversity refers to the variety of species in an
    ecosystem.
  • Climate and location are two of the most
    important factors.
  • The actions of people are making ecosystems less
    diverse by destroying habitats and food sources.
  • If one population is harmed or destroyed, the
    entire ecosystem suffers.

23
Get your coats because
  • We are going on a hike!!!!
  • On our hike, with a partner, listen for.lookand
    list all of the animals and plants you can
    identify.
  • Extra Credit On the sheet of paper, illustrate a
    map of our hike and what you saw/heard along the
    way.
