An ecosystem is made up of living and non-living things that interact in a specific area. Living things include plants and animals, while non-living components are the physical environment. Ecosystems can be terrestrial like forests or grasslands, or aquatic like freshwater or saltwater. Within each ecosystem, organisms fill different roles - producers like plants make their own food, consumers eat other organisms, and decomposers break down dead material. These relationships form food chains and webs that drive energy and nutrient flow through the system. Different species also interact through mutualism, commensalism, parasitism, and competition.

2. Do all animals have the same needs?

6.  An ecosystem is made up of all the living things and all the non-living thing
components that function together in one place.
 An ecosystem is made up of a community of living things in a physical
environment.
ECOSYSTEM = LIVING THING + NON LIVING THINGS (in one place)

7. LIVING THINGS
PLANTS
(pine, bush...)
ANIMALS
(birds, fish, mammals...)
NON-LIVING THINGS
(PHYSICAL ENVIRONMENT)
WEATHER
WATER
TYPE OF SOIL AND ROCKS
LIGHT
HUMIDITY
...

11.  TERRESTRIAL ENVIRONMENTS (ECOSYSTEMS)
FOREST ECOSYSTEM
GRASSLAND ECOSYSTEM
DESERTS ECOSYSTEM
 AQUATIC ENVIRONMENTS (ECOSYSTEMS)
FRESHWATER ECOSYSTEM ( rivers and lakes)
SALTWATER ECOSYSTEM (sea and oceans)

12. LIVING THINGS
EVERY ECOSYSTEM HAS A PARTICULAR FAUNA AND FLORA.

17.  The most important relationship in an ecosystem are related to food.
 The living things are divided into various groups depending on how they
feed.
PRODUCERS
CONSUMERS
SCAVENGERS
DECOMPOSERS

18. PRODUCERS
Living things that can make their own food.
 PLANTS are PRODUCERS (Terrestrial ecosystem)
 ALGAE are PRODUCERS (Aquatic ecosystem)

19. CONSUMERS
 Animals cannot produce their own food the way plants do, so they eat other
living things. Animals are CONSUMERS.
 PRIMARY CONSUMERS. Animals that get their energy from the plants.
Herbivores are primary consumers because they eat plants.
HERBIVOROUS
ANIMALS

20. SECUNDARY CONSUMERS. Animals that get their energy
from eating herbivorous animals.
Carnivores are secondary consumers.
CARNIVOROUS ANIMALS

21. TERTIARY CONSUMERS. They are carnivorous animals
that eat secondary consumers.

22. SCAVENGERS
Animals that eat the dead bodies of other animals.
Example: Vultures, beetles and worms.

23. DECOMPOSERS
Microorganism and fungi that decompose the remains of living
things, both animals and plants.
They decompose them into minerals which return to the soil,
keeping it fertile.
Example: Bacteria and mushrooms.

24. FOOD CHAINS
 They show how the species in an ecosystem are connected to one
another by their food relationships.
 Food chain always start with PRODUCERS.

26. FOOD WEBS
Food webs are made up of many food chains joined
together and interconnected.
They show how plants and animals are interconnected
because they are a combination of various food chains.

29. RELATIONSHIPS

30. MUTUALISM
It is the relationship between two species when
both benefit.

31. COMMENSALISM
It is the relationship between two species when one
benefits and the other remains unaffected.

32. PARASITISM
It is the relationship between two species when one
benefits the other suffers.

33. COMPETITION
It is the relationship between different species that
have the same needs.
