The Tolerance Range refers to the entire set of conditions, such as air temperature or soil moisture, under which an organism is potentially able to survive. Levels outside of this range will be lethal for the designate species.
Of the three species researched, all three of them have developed their own ways to survive and thrive in their own environments, however which species of these three would have the greatest chance of survival in an environment that is not their own. The Green Sea Turtle has developed adaptations suiting its life in the ocean, paddle-like fins, strong teeth-less jaws and a non-retractable neck. The Little Penguin has developed its own set of Adaptations as well, a thick coat of feathers, salt glands and a mouth/teeth especially designed for eating prey whole. All of these adaptations suit the animal in its own way and as a result helps it to survive in its own unique environment. The Plant on the other hand has developed adaptations that helps its survival solely, the Coast Banksia has developed thick, fire resistant bark in order to help it survive the frequent fires that it experiences. Also the fact that it will not release seeds until it comes into contact with fire. However which organism, plant or animal has the greatest tolerance range? The animals. If the conditions become to harsh for an animal it has two choices, move away or die. If a dog is out in the hot weather, severely dehydrated it will move to a shadier and cooler spot and search for a source of water in order to re-hydrate itself. Where as a plant does not have this option, it has to either adapt or die. A plant stranded in the desert has to rely on other means in order to adapt, as in the case of the cactus it has had to adapt to the hot weather by having a built in hydration source. Due to this advantage the animal clearly has the advantage when it comes to the tolerance range. While the plants may have some nifty adaptations in order to survive the harsh climate, the animals ability to relocate is greater. Interesting Facts - Penguins- Penguins' striking colouring is a matter of camouflage; from above, their black backs blend into the murky depths of the ocean. From below, their white bellies are hidden against the bright surface. Fossils place the earliest penguin relative at some 60 million years ago, meaning an ancestor of the birds we see today survived the mass extinction of the dinosaurs. Penguins evolved to stay in the Southern Hemisphere because there are no land predators, like wolves or polar bears, to take make quick work of the plump flightless prey. Turtles- The oldest known sea turtle fossils date back about 150 million years ago, making them some of the oldest creatures on Earth. Just for some context, dinosaurs became extinct 65 million years ago. It is estimated that only one hatching in a thousand will make it to adulthood. There are seven species of sea turtles, six out of these seven are close to being extinct. Humans pose the biggest threat to Sea Turtles which contributes to problems such as entanglement, habitat loss and consumption of their eggs and meat: |
