Year 7 Ecology Ecosystems and Classification - Living in Harmony Lesson 1 Power Point

1. Lesson Intentions:
 To get our knowledge ready for the topic
 To be able to locate the climate zones on a world map.
 To understand the key words : living environment and biosphere.
 To understand what an ecosystem is
 To be able to identify different types of ecosystems
 To define ecosystem, habitat, biome and population
 To explain why some ecosystems are still unexplored
Understanding the Environment

2. Starter:
This is an ecosystem.
What comes to mind when you see this picture?

3.  By definition is:
 the branch of biology that deals with the
relations of organisms to one another and to
their physical surroundings.
 the political movement that seeks to protect
the environment, especially from pollution.

4. Consider our starter:-
 What is the environment like?
 What and who lives there?
 The relationships between the animals and plants
 Human impact

5.  “It should be everyone’s birth right to
experience our wonderful planet to the
fullest, to have the chance to see polar bears,
great whales and Antarctica glaciers in real
life. I believe that it is profoundly wrong to
deprive future generations of this just so we
can continue wasting electricity and driving
oversized cars” Tim Flannery – (Flannery,
2006, p12)

6.  You have been selected to prepare a secret
document for future generations detailing the
current state of the planet. Decide on the top
10 pieces of information that you would
include. (Ideas include: information about
Earth’s forests, atmosphere, water,
population, resource use…..)
 (Store these ideas in a time capsule for
looking at later)

7.  What is an Ecosystem?

9. Try to work out the missing words
on the following slides and an
example for each!

13.  The part of the earth and its atmosphere in
which living organisms exist or that is capable
of supporting
life.

14.  The collection of
organisms in an
area along with the
important
environmental
factors
 Eg ocean
ecosystem

15. What is a Biome?
 A biome is a very large ecosystem e.g.
Tropical Rainforest or ocean Biome

16.  the natural home or environment of an animal,
plant, or other organism eg: a coral habitat

17.  A population is the
number of
organisms of the
same species or
type living in a
habitat

18. All the animals
and plants
living in an
ecosystem

19.  Advantages and disadvantages?

21.  Research the ecosystems you have been given.
Think about these questions:
 The name of the ecosystem.
 Plants found growing there.
 Animals that live there.
 Is the ecosystem artificial or natural?
 Are any of the animals or plants found in both ecosystems?
 Are any of the animals or plants found in only one ecosystem?
 If so, suggest reasons why these animals and plants live in only one type of
ecosystem.
 Is the ecosystem normally hot or cold?
 Is there much water available?
 Would it be easy for humans to explore the ecosystem? If not, why not?
 Could there be animals living in the ecosystem that we know nothing about?

22. 1. List three facts which you have
learnt.
2. Is there anything you do not
understand?
What is it?
3. How can you improve?

23. All: to be able to locate the climate zones on a world map.
To understand the key words : living environment,
biospheres, biome, ecosystem, population, habitat
Most: To be able to show understanding of the links within a
simple ecosystem
Some: To be able to suggest reasons why ecosystems might
change.
