The Sun
STAR
What it eats
The sun is a star, and therefore does not have a food resource.
What eats the sun
-Plants use the sun as a
food resource
.
(Photosynthesis)
-Humans and animals for warmth
Job/Role
-Provides
heat
and
light
-Plants can make oxygen
-Humans and animals can see
Plant Matter

What do grasshoppers eat
-
Leaves
and seeds
-Flowers
-Dead insects for extra protein

Food Chain Information
Tertiary Consumers
- a
carnivore
at the top of the food chain that feeds on other animals, mostly other carnivores

Secondary Consumers
- a
carnivore or omnivore
that mostly feeds on herbivores

Primary Consumers
- an animal that feeds on plants; an
herbivore

Producers
- a plant that is able to
produce its own food
through photosynthesis

Decomposers-
a bacteria or fungus that
breaks down dead plant or animal cells
into other nutrients
Roles in the Food Web
Snake
Plants do
photosynthesis
using sunlight, water, nutrients, and
carbon dioxide
. Chlorophyll is the green pigment that helps make food.
Pretty much every animal eats plants either
directly or indirectly.

NO BIG CHANGE
How plants are affected by Mongooses
-Plants are eaten indirectly by Mongooses
-Mongooses are
carnivores
, they don't eat veggies
How crustaceans are affected by Mongooses
Change after Mongoose
What the Arrows Mean
-
rodents
-
birds
-snakes -other insects
-humans

-Mongooses eat grasshoppers
sometimes
- Not a main source of diet for the mongoose
-
Not a big predator

MINOR CHANGE
-
Anything
on sea floor
- Plants
- Dead organisms
-Big birds
-Seals
-
Humans
(biggest predator)
- Not directly eaten
- Crabs are eaten by birds which are eaten by mongooses
- Shells are hard for mongooses to break
- Difference in the habitat make it harder


INCREASE
-Seeds -Lizards
- Leaves and bark -Spiders
- Small insects
-
Not many predators
of rats in Hawaii
- Mongooses were brought to Hawaii to control rats
-
Don't affect each other
- Rats are nocturnal
- Mongooses are diurnal

MAJOR INCREASE
- Insects -Small mice
- Spiders
- Lizards
- Rodents
- Birds
- Some rats and mice
- Sometimes consumed by mongooses
- Can eat because of
immunity to poison
MINOR INCREASE
Arrows represent the
flow of energy
throughout the web. Further along, there is less energy flowing through. The energy flows to the next consumer, until there is less and less energy flowing through. Basically, the arrows point to the thing that is eating whatever is on the other side of the arrow.
KEY
Yellow-
star
White-
producer
Green-
primary consumer
Light Pink-
secondary consumer
Light Blue-
tertiary consumers
-Rodents -Insects
-Bird - Frogs
-Rabbits - Fish
- Large Birds
- Boars
- Mongooses
- Mongooses eat snakes all time
-Mongooses are
immune to venom
, so it poison doesn't affect them
MINOR DECREASE

-Fish -Squid
-Crabs
-
Mongooses
-Rats - Cats
- Boars -Owls - Dogs
-Mongooses have decreased populations very much
- They are
hunted constantly
by rats and mongooses
- Endangerment is called "least concern", but there
aren't many left
MAJOR DECREASE
-Insects -Frogs
-Lizards -Scorpions
-
Birds
- Bird eggs
-Snakes, poisonous or not
No main predators.
They are small,
very fast,
and immune to venom. It's almost like nothing can stop them.
