How snakes are affected by mongooses

How shearwaters are affected by mongooses

White-

producer

No main predators. They are small, very fast, and immune to venom. It's almost like nothing can stop them.

- Mongooses eat snakes all time

-Mongooses are immune to venom, so it poison doesn't affect them

Green-

primary consumer

-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

-Anything on sea floor

- Plants

- Dead organisms

What eats crustaceans

Rats

Crustaceans

-Big birds

-Seals

-Humans (biggest predator)

-Not many predators of rats in Hawaii

- Mongooses were brought to Hawaii to control rats

MINOR INCREASE

How crustaceans are affected by Mongooses

How rats are affected by Mongooses

- Don't affect each other

- Rats are nocturnal

- Mongooses are diurnal

- 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

Roles in the Food Web

PRODUCER

-Mongooses eat grasshoppers sometimes

- Not a main source of diet for the mongoose

- Not a big predator

What they eat

Change after Small Asian Mongoose

Plants do photosynthesis using sunlight, water, nutrients, and carbon dioxide. Chlorophyll is the green pigment that helps make food.

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

MINOR CHANGE

What eats plants

The Sun

Pretty much every animal eats plants either directly or indirectly.

STAR

What the Arrows Mean

How plants are affected by Mongooses

What it eats

The sun is a star, and therefore does not have a food resource.

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.

-Plants are eaten indirectly by Mongooses

-Mongooses are carnivores, they don't eat veggies

What eats the sun

Change after Small Asian Mongoose

-Plants use the sun as a food resource.

(Photosynthesis)

NO BIG CHANGE

-Humans and animals for warmth

Job/Role

-Provides heat and light

-Plants can make oxygen

-Humans and animals can see
