Response
1. Short Legs and Short Necks
islands with low shrubbery have tortoises with short legs and necks, because the tortoise has adapted to make it eating easier
2. Long Necks and Long Legs
islands with tall vegetation have tortoises with longer necks and legs, this adaptation occurred to allow the turtle to reach the plant
3. Shell Shapes
the different shapes and forms of the Galapagos tortoise shell varies depending on the island they're on, each tortoise has different shapes and colors to fit camouflage or protection against predators

Organism Interaction
The galapagos tortoise is part of the Animalia Kingdom, I knows this because the tortoise is multicellular, have organelles with w/ a nucleus but no chloroplasts or cell walls, and the tortoise acquires nutrients through eating.

Biotic factors
1. amount of foliage and shrubs the tortoise feeds on
2. lack or overflow of predators
3. cutting down of forests/ areas on the galapagos island
Abiotic
1. rainfall
2. tempature
3. drought
On the Galapagos Island, it's very warm and tropical the perfect place for a vacation. So in turn humans turn the land into resorts/hotels and ruin the ecosystems and food sources of the organisms. In previous years humans have brought the common pet dog onto the island, and being that the tortoise is slow and has a vulnerable neck make it an easy prey. This will cause the number of surviving to decrease, when they are already on the brink of extinction. But the galapagos tortoise population has been transferred to the san diego zoo, because they're so close to being extinct.
Parasitism
Ectoparasites suck blood from the tortoise leaving it weak.
Mutualistic
Darwin's finch work with the tortoise to remove the ectoparasites, while benefiting the tortoise it also gives the finch easy prey.
Commensalism
The tortoise feeds off the plants on the islands.
Innate Behavior
1. Hiding there arms, legs and head into there shell, this is an instinct used when the tortoise is in danger.
2. being able to mate with another tortoise, this courting cannot and is not practiced or learned.
