FOOD CHAINS
All living things need energy. Food chains show how energy passes between organisms in an ecosystem. We classify organisms into PRODUCERS, CONSUMERS, DECOMPOSERS.

FOOD WEBS:
show the reality that many species have multiple predators and preys
Most living things belong to more than one food chain. Several food chains can be connected to make food webs.
Components in food webs
PREDATORS: animals that capture, kill and eat an animal of another species
PREYS: animals that are eaten by a predator
PARASITES: relies on another living thing called host
SCAVENGERS: eat dead plants and animals that other living things kill
Look at p. 22 and 23 and classify into:

WHAT CAUSES EXTINCTION?
HABITAT DESTRUCTION
OVERHUNTING
GLOBAL WARMING
AIR POLLUTION
WATER POLLUTION
OVERFISHING
DEFORESTATION
All these can cause an entire species to die, that is extinction
The more species die out, the less biodiversity we have

CHALLENGE!
How can I do it?
1. Think of an habitat2. Think of the animals that live there 3. Use a shoe box to create it
LARGE AMOUNT OF TREES ARE CUT DOWN FOR OTHER PURPOSES, LIKE FARMING. IT CAUSES HABITAT DESTRUCTION
CARS AND LARGE FACTORIES CAUSE IT
ONE SPECIES BENEFIT, THE OTHER IS UNAFFECTED. F. EX: - FLOWERS AND BEES - TREES AND BIRDS
MANY SPECIES ARE UNDER THREAT BECAUSE OF THESE REASONS
INDIVIDUALS COMPETE FOR A GOAL. F. EX: - LIONS DEFENDING TERRITORIES
ONE SPECIES BENEFIT, THE OTHER IS NEGATIVELY AFFECTED. F. EX - LICE ON OUR HEAD - TICKS ON OUR DOGS' SKIN
teamwork between individuals of the same species to achieve a goal. F. EX - Fish school
- TOUCAN - RED- EYE TREE FROG - BAT - ANTEATER - CAIMAN - PIRANHA
- JAGUAR - GREEN ANACONDA
BOTH SPECIES BENEFIT. F. EX: - BIRDS AND BIG MAMMALS - FISH AND ANEMONE
- LEAFCUTTER ANT - TERMITE - CAPYBARA
